A review of potentially low-cost sorbents for heavy metals
TLDR
The use of low-cost sorbents has been investigated as a replacement for current costly methods of removing heavy metals from solution as mentioned in this paper, where natural materials or waste products from certain industries with a high capacity for heavy metals can be obtained, employed and disposed of with little cost.About:

Biosorption of cadmium by biomass of marine algae
TL;DR: Biomass of nonliving, dried brown marine algae Sargassum natans, Fucus vesiculosus, and Ascophyllum nodosum demonstrated high equilibrium uptake of cadmium from aqueous solutions and there was no damage to the biosorbent which retained its macroscopic appearance and performance in repeated metal uptake/elution cycles.

Removal of hexavalent chromium using sphagnum moss peat
Deepak Sharma,C.F. Forster +1 more
TL;DR: In this article, it was shown that sphagnum moss peat, which is essentially oligotrophic, in concentrations ranging from 4 to 40 g/l can be used effectively to remove hexavalent chromium from aqueous solutions.

The Removal of Heavy Metals by Using Agricultural Wastes
Yüksel Orhan,Hanife Büyükgüngör +1 more
TL;DR: In this paper, the removal of heavy metals from wastewater using adsorbants such as waste tea, Turkish coffee, exhausted coffee, nut and walnut shells has been investigated, and batch studies showed that these adsorbents exhibit a good adsorption potential for A1 (III) metalions.
Journal ArticleDOI
Synthesis of porous-magnetic chitosan beads for removal of cadmium ions from wastewater
TL;DR: Chitosan is a glucosamine biopolymer capable of adsorbing transition-metal ions from aqueous solution as mentioned in this paper, and it can be crosslinked with glutaraldehyde and then freeze dried.
Journal ArticleDOI
Adsorption of chromium (III), chromium (VI), and silver (I) on bentonite
TL;DR: In this article, the sorption of chromate ions from aqueous solutions on bentonite has been studied by a batch technique and the mean free energy of sorption, E, for Cr(VI) is 10 kJ/mol.
