TLDR
In this paper, four organic wastes were tested as potential adsorbents for hexavalent chromium and the results showed that this type of material could certainly be considered for this purpose with the best results being achieved at pH values of 1·5-3·0.About:

Alexander E. Burakov,Evgeny Galunin,I.V. Burakova,Anastassia E. Kucherova,Shilpi Agarwal,Alexey Tkachev,Vinod Kumar Gupta +6 more
TL;DR: Detailed information and review on the adsorption of noxious heavy metal ions from wastewater effluents using various adsorbents - i.e., conventional (activated carbons, zeolites, clays, biosorbents, and industrial by-products) and nanostructured (fullerenes, carbon nanotubes, graphenes) is presented.

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.

Cr(VI) and Cr(III) removal from aqueous solution by raw and modified lignocellulosic materials: a review.
TL;DR: This study is a review of the recent literature on the use of natural and modified lignocellulosic residues for Cr adsorption and finds that many by-products of agriculture have proved to be suitable low cost adsorbents for Cr(VI) and Cr(III) removal from water.

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.

Removal of chromium(VI) from solution by coconut husk and palm pressed fibres
TL;DR: In this article, the results of various columns containing mixed media of CHF or PPF in soil system demonstrated that both substrate could also be used as barriers in the landfill to maximize immobilization of toxic metal such as Cr(VI) in leachates.
