Tea waste as a low cost adsorbent for the removal of Cu and Pb from wastewater
TL;DR: In this article, the adsorption of copper and lead ions onto tea waste from aqueous solutions was studied to enable comparison with alternative commonly available absorbents, and the equilibrium data were satisfactorily fitted to Langmuir and Freundlich isotherms.
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.

Biosorption mechanism of nine different heavy metals onto biomatrix from rice husk
TL;DR: A biomatrix was prepared from rice husk, a lignocellulosic waste from agro-industry, for the removal of several heavy metals as a function of pH and metal concentrations in single and mixed solutions, which indicated the presence of several functional groups for binding metal ions.
