Spirulina are multicellular and filamentous blue-green algae that has gained considerable popularity in the health food industry and increasingly as a protein and vitamin supplement to aquaculture diets. It grows in water, can be harvested and processed easily and has very high macro- and micro-nutrient contents.The present work was carried out in the department of Zoology and Applied Aquaculture, Barkatullah University. Following Zarrouk formula, Spirulina was cultured using innoculum brought from Offer Nalayan, Chennai. The culture was carried out in plastic tubs which were maintained serially and tap water was added having temperature range of 28-300c. The first harvesting was done after 15 days of culture and further harvesting was performed after every fourth day. The chemicals were added just after every harvesting by calculation as given in the materials and methods. Proper agitation was done after an interval of half an hour for the whole day for the proper reproduction of Spirulina in the tubs. Harvesting was done in the morning every fourth day. The culture was performed for two consecutive months.The wet slurry obtained every 4 days from the culture tubs on an average was found to be 12 gm from each tub in two months culture and harvesting. The final dried mass obtained after each harvesting was 10 gms from all the tubs with an optimum average range of pH of 12, temperature of 300C, density of 0.25 cm and growth upto an average of 1.2 cm.

A newer fast, convenient and inexpensive quantitative method for the determination of Thiomalic acid using photochemical exchange reaction of sodium nitroprusside has been investigated. Sodium nitroprusside is a photolabile complex and it undergoes photochemical ligand exchange reactions rapidly. Some recent efforts have been made to utilise such reactions for the estimation of some sulphur containing anions and electron rich organic molecules. The progress of the reaction is observed spectrophotometrically. The effects of different parameters like pH, change of concentration of sodium nitroprusside, concentration of ligands, light intensity etc. on percentage error was investigated. The efforts were made to minimise the percentage error and some optimum conditions were obtained. Such reaction can be used for the determination of Thiomalic acid in the range of millimoles to micromoles, hence it is important to know whether such estimations can be done successfully and that to with the desired accuracy.

IM-5 contributes to the isomerization of p-DEB to m-DEB. The isomerization step can generally follow two models: (i) the isomerization of p-diethyl benzene to m-diethyl benzene takes place exclusively on the outer surface, or (ii) the isomerization occurs on the acid sites located both on the outer surface and inside the zeolite channels. Therefore, their elimination of acid sites from the zeolite surface will be helpful for the reaction selectivity with respect to the desired dialkylaromatics.However, if the zeolite modification can be done, not only leading to elimination of the surface sites but also lead to narrowing of the pore opening, like,with the surface silylation or deposition of metal oxides, such zeolite modification results increase p- selectivity.
The heavy metal contamination is an environmental threat as serious as global warming. Removal of Cu+2 ions in aqueous solution has been analysed by using Chitosan reinforced by Banana stem fibre. Batch adsorption experiments were carried as a function of adsorbent dosage, pH, contact time, initial metal ion concentration and temperature. The optimum pH was found to be 5. The experimental data were tested with Langmuir, Freundlich, Temkin and Dubinin-Radushkevich isotherms and the data have been fitted very well with the Langmuir isotherm. The energy of adsorption showed that the adsorption of Copper by Chitosan-Banana stem fibre beads was physical adsorption.Adsorption kinetics data were modeled with the application of Pseudo first order, Pseudo second order, Elovich and Intra-particle diffusion models. The results revealed that the Pseudo second order model was the best fitting model. . The adsorption mechanism followed two stages in which the first one was fast and the other was slower. The Boyd plot exposed that the intra-particle diffusion was the rate controlling step of the adsorption process of Copper (II) ions by Chitosan-Banana stem fibre beads.

The physico-chemical analysis of ground water and its adverse health effect in Berla Tehsil of Durg district of Chhattisgarh, India are undertaken. In the present study, fifteen water samples, were collected from the different sites during June 2012 to Dec 2012 from deep bore well and hand pump. Physico-chemical parameters analyzed for pH, EC, TDS, alkalinity, turbidity, total hardness and content of fluoride, lead, arsenic, iron, sulphate and chloride were studied and compared with the standard values prescribed by World Health Organization (WHO) and Bureau of Indian Standard (BIS). The ground water is characterized by slight high fluoride content in two sample and slightly rich in iron probably due to industrial effluents of Bhilai steel plant. However, most of the water samples did not have high concentrations of the toxic contaminants. The present investigation revealed that some of the ground water sample of Berla village of durg district is not suitable for drinking purpose and they need to proper treatment before use. The process of removal of excess fluoride from water is reverse osmosis, ion exchange devices and bio-remedies. One of bio remedies method is natural adsorption such as Mangrove plant(Sonneratia Apetala) leaf powder (MPLP) and Coconut(Cocos nucifera) coir pith (CCP).
