Removal of U(VI) from Leaching Process Wastewater by Zero-Valent Iron

Abstract:

The removing effectiveness of U(VI) in leaching process wastewater by Zero-valent iron (ZVI)(iron powder and waste scrap) has been studied. The effects of the dosage of ZVI, pH, shaking time and temperature on treatment effiency are investigated. The results showed that: ZVI has very good removal effect on U (VI), and when pH value of solution is 6, the dosage of ZVI is 1.5 g, the shaking time is 80 min, the removal rate reached 98.6%.The removing efficiency of iron powder is sightly better than waster scrap.Acorrding to the experiment, the optimum experiment conditions and the influence of these parameters are obtained. The removal mechanism of U(VI) in leaching process wastewater by ZVI is discussed.
