Reduction Remediation of Hexavalent Chromium by Pyrite in the Aqueous Phase

Zaidi Houda, Qian Wang , Yanjun Wu and Xinhua Xu

Abstract:
The objective of this study was to investigate the reduction remediation of hexavalent chromium by pyrite in the aqueous phase, batch experiment indicated that: (1) the rate of chromate removal was dependent on the initial pyrite concentration; (2) the Cr (VI) reduction rate increased with an decrease in initial Cr (VI) concentration; (3) the Cr (VI) reduction was found to be pH dependent, the high reduction of Cr (VI) under acidic conditions; (4) the rate of chromium removal increased with increased temperature; (5) the Cr (VI) reduction depends on the pyrite type. The effective removal of Cr (VI) by pyrite suggests that the use of pyrite for the treatment of wastewater containing Cr (VI) is an innovative method that constitutes a simple, effective and economical means for wastewater treatment.
