A volumetric continuous Tilak Air Sampler was employed for exploring microbial airspora over a bajra field at Kada from 10 th July to 22 nd October 2003 has been carried out. In all 60 airborne components were trapped & identified. An trapped airborne mycofloral components have been categorized as "spore types" & hyphal fragments, insect parts, plant parts pollen grains & protozoan cysts were categorised under artificially formed group "other types". Incidence of the spore trapped trough out the season-The maximum monthly concentration (12852/m 3 of air) was noted in the month of September 2003. The highest daily mean concentration (770/m 3 of air) was recorded on 18 th September 2003. In the Kharif (bajra) season, cladosporium Stood First in rank in the order of dominance among the total catches. Its mean contribution to the total airspora was (20.55%). It was followed by Alternaria (7.23%), Njigrospora (5.99%), Curvularia (5.78%), Rust Spores (5.40%), Periconia (5.35%), hypal fragments (4.74%), Basidiospores (4.31%), Helminthosporium (4.07%), Pseudotorulla (2.50%). Weather parameter such as rainfall, humidity, wind velocity & temperature showed pronounced effect on liberation of spores qualitatively and quantitatively.

Equilibrium sorption of Nickel on Vignaunguiculata husk was studied using batch adsorption method. The applicability of Langmuir, Freundlich, Dubinin-Radushkevich, and Temkin equations was investigated. Of the four adsorption isotherms, the R2 value of Temkin isotherm model was the highest and exhibited the best fit with the experimental data. The maximum monolayer coverage (Q0) from Langmuir isotherm model was determined to be 2000.00 mg/g, the separation factor indicating a favorable sorption experiment is 0.594. According to Freundlich isotherm model the sorption intensity (n) which is indication of favorable sorption is 0.692 with correlation coefficient 0.945. The heat of adsorption process was determined from Temkin isotherm model (1626.009 J/mole) and the mean free energy was estimated from Dubinin-Radushkevich isotherm model (8.558 × 10-4 J/mol). Which indicate that adsorption experiment followed a physical process. © EM International.

Experimental investigation was carried out by using commercially available husk of green gram (phaseolusaureus) seed to removal ofmethylene blue from aqueous medium. Husk of green gram seed was characterized by performing particle size distribution. The effect of contact time, effect of initial concentration of dye, effect of dosage, effect of salt, effect of pH, zero point pH and effect of temperature were studied in batch technique. Adsorption kinetic was verified by pseudo-first-order and pseudo-second-order models. The rate of adsorption of methylene bluefollowed by pseudo-second-order model for the dye concentration studied in the present case. Adsorption of methylene blue on green gram (phaseolusaureus) seed husk is also followed by Langmuir and Freundlich adsorption isotherm.

In this work, batch adsorption experiments were carried out to study the adsorption of crystal violet (CV) dye from aqueous solutions using Black gran seed husk (BGSH). The effects of major variables governing the efficiency of the process such as contact time, initial CV concentration. BGSH dose, pH and temperature were investigated.. The adsorption kinetic data were analyzed using pseudo-first order and pseudo-second order models. It was found that pseudo-first order kinetic model was the most appropriate model, describing the adsorption kinetics. Adsorption isotherm of CV dye onto the BGSH was determined at 306.2, 311.2, 316.2, 321.2, and 326.2 K with 50 mg/L as initial concentration of CV . Adsorption equilibrium was attained within 24 hours. Equilibrium data was fitted to the Langmuir and Freundlich adsorption isotherm models and isotherm constants were determined. The equilibrium data were best fitted by the Langmuir isotherm model than Freundlich model. Thermodynamic parameters such as Gibb's free energy change (ΔG0),enthalpy change (ΔH0)and entropy change (ΔS0)were calculated. The negative values of ΔH0and ΔG0 indicates that the CV adsorption process is exothermic and spontaneous in nature. Experimental results have shown that, the amount of CV adsorption increased with increasing the initial concentration of the dye and BGSH dose, while the amount of CV adsorption decreased with increasing the temperature. © 2014, Sphinx Knowledge House.
