Physicochemical characteristics of groundwater and municipal water in Amalner town by taking water samples from five different stations. The study was carried out by collecting four groundwater samples (Two open well, two bore well) and one municipal water sample during November 2007-February 2008. The results were compared with standards prescribed by WHO and ISI 10500-91. Total 15 parameters were analysed. It was found that the underground water was contaminated at few sampling sites namely Shirud Naka, Cotton Market and Shivaji Nagar. The sampling sites Dekhu road showed physicochemical parameters within the water quality standards and the quality of water is good and it is fit for drinking purpose. The correlation coefficients were calculated for water quality assessment.

The present study was aimed at assessing ground water chemistry, with reference to drinking water quality; the Anjani and Jhiri river catchment area in the Jalgaon district, northern Maharashtra, India, was selected. Ten ground water samples were collected from different locations in two urban areas (Daharangaon and Erandol) and some samples from rural water supply wells during the pre-monsoon 2011 and post-monsoon 2011 seasons. Trace elements were analysed from collected groundwater samples using standard techniques. The ground water pollution observed at some study area sites was mainly due to waste disposal and agricultural activities and vehicles burning fossil fuel. The present investigation was based on the occurrence of trace elements such as Fe, Zn, Cu, Ni, Mn, Pb and Cd in groundwater samples, concentration ranging from 0 to 0.096 ppm, 0.066 to 0.427 ppm, 0 to 0.012, 0.026 to 0.361 ppm, 0 to 0.160 ppm, 0.968 to 1.516 ppm and 0 to 1.064 ppm, respectively. The analysis of ground water chemistry and results were compared to BIS drinking water standards. The concentration of lead, cadmium and nickel exceeded the maximum permissible limit, as per BIS drinking water standards.

In recent years, there is growing interest in searching herbal medicines. Herbal medicines are safe drugs than the synthetic drugs. Well planned extensive and intensive search of medicinal plants is very useful in tracing the new drug plants. For this purpose medicinal plants were collected from Patnadevi forest. An enumeration of 30 medicinal plants of Patnadevi forest, Chalisgaon Taluka, Maharashtra are given in the paper.

Commercially available technical grade nonionic surfactants usually contain impurities and have a broad distribution of molecular weight owing to degree of elhoxylalion. It has been shown that the surface tension method (Wilhelmy plate) is very sensitive if impurities are present in surfactant. Much lower CMC values are obtained for technical grade surfactants with the surface tension method than with the dye solubilization method. The CMC determined by dye solubilization technique are in fair agreement with the values obtained by other available methods. The change in critical micellar concentration of Triton X-100 and Triton X-114 has been studied through the influence of additive Chloramine-T in aqueous medium by measuring the absorbance of the pure surfactant and with Chloramine-T in presence of water insoluble dye Orange-OT by using dye solubilization technique. The absorbance was found to increase with increased concentration of pure surfactant Triton X-100 and Triton X-114. The absorbance of the mixed systems with Chloramine-T also shows the same trend. The CMC of pure surfactant get decreased with increased concentration of additive Chloramine-T. The influence of additive Chloramine-T on the absorbance of Triton X-100 and Triton X-114 is clear indication that the phenomenon of dye micellization is associated with the different micelles coalescing.

Clouding behavior of non-ionic surfactant have been worked out in presence of Myo-ionositol in order to study the molecular interactions of additive on non-ionic surfactant. Tween-40 have been selected as surfactant while Myoi-inositol as an additive. Clouding of Tween-40 has been studied as a pure and in presence of additive at various concentrations, it has been found that below 0.1 Wt % of myo-inositol did not show marked effect on CP of surfactant. Considering CP as threshold temperature of solubility, the thermodynamic parameter of solubilization of pure surfactant and surfactant additive system has been evaluated. From this study, the process of clouding is guided by both enthalpy and entropy and overall process is exothermic.

The phenomenon of micellization of non-ionic surfactant Tween 40 has been studied through the influence of additives polyvinyl sulphonic acid in aqueous medium by measuring the cloud points of the pure surfactant and with polyvinyl sulphonic acid. The cloud points of pure surfactant Tween 40 found to be increased with increased [Tween-40]. The cloud points of mixed system shows same trends with increased [concentration of polyvinyl sulphonic acid]. The influence of polyvinyl sulphonic acid on the cloud point of Tween 40 is a clear indication that the phenomenon of clouding is associated with the different micelles coalescing. Considering cloud point as threshold temperature of the solubility, the thermodynamic parameters of clouding process (ΔG° cl, ΔH° cl and ΔS° cl) have been evaluated using "phase separation model". The phase separation results from micelle-micelle interaction. It is found that the overall clouding process is exothermic and DH° cl > TΔS° cl indicating that the process of clouding is guided by both enthalpy and entropy. This work supports the conjecture that the clouding is critical phenomenon rather than the growth of micelles. Findings of the present work supports to made the probable evidence of polymer-surfactant interactions in aqueous medium.

The Phenomenon of micellization of non-ionic surfactant Tween-20 has been studied by measuring cloud point (cp) of the pure surfactant and mixed system with myo-inositol. The cp of pure surfactant found to be increased with increased tween-20.The cp of mixed system also shows same trend with increased myo-inositol. The influence of myo-inositol on cloud point of Tween-20 is clear identification that the phenomenon of clouding is associated with different micellization coalescing. Considering the cp as the threshold temperature of solubility, the thermodynamic parameters of clouding process (ΔG o cl, ΔH o cl and ΔS o cl) have been evaluated using "phase separation model." The phase separation results from micelle-micelle interactions. It is found that overall clouding process is exothermic indicating that process of clouding is guided by both enthalpy and entropy. Finding of present work support to make the probable evidence of additive surfactant interactions in aqueous medium.

To study the effect of tuned head group polarity on physicochemical properties of cetyl trimethyl ammonium bromide has been studied by conductance, surface tension and viscosity measurements. The critical micelle concentration was determined by conductance and surface tension measurements. Conductance measurement data was used to compute critical micelle concentration, average degree of micelle ionization and thermodynamic parameter of micellization. Surface tension data were further used to determine the surface excess concentration, minimum area per molecule at air-water interface. The decrease in effective Gibb's free energy with increase in head group polarity indicates that the micellization process is more favored over adsorption at the air-water interface. The intrinsic viscosity and hydration of micelle were observed to increase with increase in head group polarity and decrease with increase in temperature. © Carl Hanser Verlag GmbH & Co. KG.

The present study designed for phytochemical analysis, antibacterial, antifungal activity of saponifiable matter of petroleum ether extract of leaves of Butea monosperma belongs to family Fabaceae. The extraction preformed by soxhlet extractor and identification was performed by phytochemical test. The petroleum ether extract of leaves of Butea monosperma was saponified using 1 M alcoholic KOH, to separate saponifiable (fatty material) and unsaponofibale matter. A comprehensive phytochemical investigation of the saponifiable matter of petroleum ether extract of leaves of Butea monosperma resulted in the isolation and identification of four known compounds Palmitic acid, tetradecanoic acid, oleic acid and a-linolenic acid. To our best of knowledge, these four compounds were isolated from leaves of plant for the first time. Their structures were identified by physical, chemical, elemental analysis and spectroscopic methods including UV, FTIR, MS, 1H NMR, 13C NMR. The study was further continued for screening of antibacterial activity against E. coli, P. aeruginosa, B. subtilis, S. aureus and antifungal activity screened against A. niger and C. albicans using agar diffusion assay.
