| Abstract: | Chromiumcontaining slag is one kind of poisonous slag produced in the manufacture of chromate with watersoluble and carcinogenic element Cr(VI).Detoxification of chromiumcontaining slag has been a great subject in the field of environmental protection throughout the world.In the paper,the detoxification mechanisms,industrial processes,specifications and the actual effects of the methods,including reduction process by sodium sulfide or ferrous sulfate,extractionexchange process,are summarized comprehensively on the basis of the review of hydrobased processes of chromiumcontaining slag at home and abroad.The prospect of the new technology on detoxification of the chromiumcontaining slag by microorganisms is also proposed. |
