ABSTRACT

A review of heavy metal sequestration from contaminated water has been carried out in this article. Some metal ion sequestration techniques used over the years have some demerits, ranging from generation of sludge to high operational cost. Adsorption process using activated carbons derived from plants has been found cost effective and environmentally nuisance-free. In this review, various plant- based adsorbents for heavy metal sequestration have been studied. The application of some adsorption models such as single and multi-component isotherms, adsorption thermodynamics, and kinetics as well as the effect of process parameters on heavy metal sequestration using plant-based adsorbents has also been reviewed so as to better explain the adsorption process.
