Adsorbents for Cd2+ removal from water waste: A short review of the recent development

Abstract

Cd2+ is a highly toxic heavy metallic ion, which is found in mineral rocks and contaminated areas. Several different methods have been developed for the Cd2+ removal from contaminated water. Low cost adsorbents have been recommended as cadmium ions removers for aqueous effluents, replacing conventional materials of higher cost. In this review, an extensive list of the low cost adsorbent materials, such as agro-industrial wastes and biosorbents were compiled. The potential of various low cost adsorbents, for removing Cd2+ from water systems, was analyzed. ©2012 Nova Science Publishers, Inc. All rights reserved.
