Abstract

The extraction of chromium (VI) from hydrochloric, sulphuric, and phosphoric acidsolutions with Tri benzylamine (TBA) in chloroform has been studied. The extractions from hydrochloric and sulphuric acid solutions are nearly quantitative and are partial from phosphoric acid solutions. The optimum conditions for extraction were established from the study of the effect of several variables like-concentration of amine, metal ion, acidity, foreign ions etc. The extracted species are identified. The method has been applied for the recovery and determination of chromium in real as well as synthetic samples.

Abstract

Physico-Chemical analysis of well and bore well water samples was carried out from eleven sampling stations of Guntur District for a period of two months from August to September 2009. The analysis of different parameters namely-pH, turbidity, color, total alkalinity, total hardness, chloride, sulphate, nitrate, TDS, DO, BOD, COD and fluoride were carried out as per standard methods. The parametric ratios and variation of temperature with D.O and Nitrate were studied. The results indicate that the fluoride and calcium in some sampling stations were found above the permissible limits.
