TREATMENT OF ELECTROPLATING EFFLUENTS FOR REDUCTION OF CHROMIUM

摘要

Chromium (VI) is moderate to severe toxic which is responsible to produce deleteriouseffects in human beings and animals. The sources of contamination of chromium in natural waters and inthe environment are from electroplating, tanning industries and waste solution from oxidative dyeing andleaching from sanitary land – fills. Hence the determination of chromium is of great interest to analyticaland environmental chemists. The present study deals with the determination of physico-chemicalparameters of electroplating effluents collected from a local industry. Probable reduction of hexa valentchromium was also attempted using standard iron (II) sulphate solution
