Description
Summary:<p>This paper presents the alternative removal of chromium from the aqueous environment. Rapid growth in industry and population has resulted in environmental degradation. Chromium is a priority metal pollutant introduced into the water bodies from many industrial processes such as tanning, metal processing, electroplating, paint manufacturing, steel fabrication and agricultural runoff. Chromium occurs in the aquatic environment as both trivalent and hexavalent states. Hexavalent chromium, which is primarily present in the form of chromate (CrO&#8324
