Cr^VI Adsorption Using Black Nickel Mud as Adsorbent

Abstract

Rapid industrialization and usage of heavy metals in industrial processes have resulted in unprecedented increase in the heavy metal flux into groundwater. Hexavalent chromium is one of elements with high health risks such as mutagenicity and carcinogenicity. Adsorption is economically feasible alternative of chromium removal. We have used spectrophotometric method for monitoring of hexavalent chromium adsorption from aqueous solution with the use of black as adsorbent. We have monitored the influence of temperature and surface treatment on the adsorption process.
