The green seaweed Caulerpha sertularioides was treated with five different types of solvents such as Acetone, Chloroform, Ethanol, Ethyl acetate and methanol. The extracts of the selected seaweeds was extracted by using soxhlet apparatus. The antibacterial activities were carried out by the agar well diffusion method. In this present study showed the significant antibacterial activity against six bacterial pathogens (Staphylococcus aureus, Bacillus subtilis, Lactobacillus acidophilus, Pseudomonas aeruginosa, E.coli., and Proteus mirabilis) and the best activities were recorded in the 100μg/ml concentration. In low concentration (40μg/ml), the highest activities were seen in ethanol extract against B. subtilis, E. coli and Proteus mirabilis like 6mm, 6mm and 7mm respectively. The extracts of ethanol and ethyl acetate were showed considerable activity against all the organisms but at the same time there were no activity in the chloroform extract.

Microwave-assisted route for the synthesis of nanomaterials has gained importance in the field of synthetic technology, because of its faster, cleaner and cost effectiveness than the other conventional and wet chemical methods for the preparation of metal sulphide nanoparticles. In the present work, synthesis of metal sulphide nanoparticles viz., PbS, CdS were carried out by microwave-assisted route without connecting any refluxing system and through the thermal decomposition of their respective metal acetate precursors employing sodium hydroxide as a fuel. The metal sulphide nanoparticles are then characterized for their size by employing X-ray diffraction(XRD) pattern. The morphology of the samples are nano globular form on the basis of scanning electron microscopy. The obtained yield percentage, grain size indicate that the nanomaterials prepared by the method adopted in the present study are important and more useful owing to the low cost of preparation.


This paper deals with sources of fluoride and methods of its spread and a survey was conducted in these Villages by a specially prepared questionnaire. This survey reveals the fact that majority of the residents of these Villages were affected by fluorosis. The primary aim of this survey was to find out the contamination of fluoride and other parameters in the samples of drinking water from different parts of these areas. Copyright © EM International.

Ground water samples collected from four villages of Radhapuram Taluk have been analysed from December 2010 to April 2011 for some water quality parameters such as fluoride, pH,EC, total hardness, total alkalinity, Chlorides and salinity. Seasonally lowest and highest values of all these parameters are recorded during summer and rainy season respectively in all the four villages. Majority of the values of the water quality parameters are found above the limit prescribed by ICMR. Copyright © EM International.


Fluoride concentration in ground water and ground water quality parameters in ground water samples from three villages of Tirunelveli District were assessed. It is found that fluoride concentration in ground water is heterogeneously distributed and more than 1 ppm, which is much above the permissible limits prescribed by ICMR. Fluoride content upto 1 ppm is considered as "safe" and fluoride beyond that limit leads to dental and skeletal fluorosis . Copyright © EM International.


The present work deals with the quality of water parameters such as pH, electrical conductivity, total hardness, calcium, magnesium, total alkalinity, chloride, salinity andfluoride in Kodumudiaru dam water. These parameters are recorded by means of collecting twenty samples of water from the dam and near by ponds connected through canal. Experimental analysis shows that concentration of fluoride in surface water is less than 1 ppm, which is the permissible limit. The other parameters are also present within the limit.

The suitability of water for drinking and irrigational purposes is studied by collecting 25 samples. Among the 25, 10 samples were collected from the ponds and 15 samples from borewells located in and around Vallioor. Samples were analysed for water quality parameters such as pH, electrical conductivity, total hardness, calcium, magnesium, total alkalinity, chloride and salinity. Copyright © EM International.

This paper deals with the analysis of removal of fluorides from drinking water. A simple and economic method of defluoridation of drinking water is the adoption of drumstick bark and its leaves as an adsorbentThe botanical name of drumstick is Muringa odecifera. It has the high capacity of removing fluorides from the drinking water.Drumstick leaves are used as leafy vegetables in the diet of South Indians. © EM International.

Dry fruit of tamarind and its seeds has been used as an adsorbent for defluoridation of drinking water which is a simple and economic method. The botanical name of tamarind is Tamarindus indica. It has the highest capacity of removing fluoride from drinking water. © EM International.
