Journal ArticleDOI
Low-cost adsorbents for heavy metals uptake from contaminated water: a review.
TL;DR: The technical feasibility of various low-cost adsorbents for heavy metal removal from contaminated water has been reviewed and it is evident from the literature survey of about 100 papers that low- cost adsorbent have demonstrated outstanding removal capabilities for certain metal ions as compared to activated carbon.
Journal ArticleDOI
Physico-chemical treatment techniques for wastewater laden with heavy metals
TL;DR: In this article, the technical applicability of various physico-chemical treatments for the removal of heavy metals such as Cd(II), Cr(III, Cr(VI), Cu(II, Ni(II) and Zn(II).
Journal ArticleDOI
Cr(VI) removal from synthetic wastewater using coconut shell charcoal and commercial activated carbon modified with oxidizing agents and/or chitosan
TL;DR: It is evident that adsorbents chemically modified with an oxidizing agent demonstrate better Cr(VI) removal capabilities than as-received adsorbent in terms of adsorption rate.
Journal ArticleDOI
Comparisons of low-cost adsorbents for treating wastewaters laden with heavy metals.
TL;DR: Low-cost adsorbents can be viable alternatives to activated carbon for the treatment of metals-contaminated wastewater and vary, depending on the characteristics of the individual adsorbent, the extent of surface modification and the initial concentration of the adsorbate.
Journal ArticleDOI
Heavy metal removal from contaminated sludge for land application: a review.
TL;DR: A comparative review and critical analysis of the application of chemical extraction, bioleaching, electroreclamation, and supercritical fluid extraction, in removing heavy metals from contaminated sludges is presented, revealing a broad range in metal extraction efficiencies of the different extraction technologies.
