摘要

The suitability of sulphate and sulphite salts for the remediation of contaminated ground water at laboratory scale is reported in this paper. Studies reveal that the amount of sulphate salt consumed is greater than the amount of sulphite salts. The efficiency of sulphite salt is more at pH-2 whereas for sulphate salt it is at pH-2.5. An anomaly in the behaviour of sulphite salt in the reaction environment is noticed. However, complete reduction of Cr(VI) to zero level is reported without dilution in the contaminated ground water. Data obtained are compared with previous work with Na2S2U4 and SnCb. Best reducing agent for complete removal of hazardous Cr(VI) at COPR dump site is proposed. Site remediation highlighted could solve the problems of COPR dump sites exist worldwide and could produce water for industrial purpose.
