Hexavalent chromium removal by various adsorbents: Powdered activated carbon, chitosan, and single/multi-walled carbon nanotubes
TL;DR: In this article, the adsorption behavior of ppb-level aqueous solutions of hexavalent chromium [Cr(VI)] on four different adsorbents was investigated as a function of pH, contact time, initial Cr(VI) concentration, adsorbent dose, and the copresence of competing anions.

Muhammad Bilal,Tahir Rasheed,Juan Eduardo Sosa-Hernández,Ali Raza,Faran Nabeel,Hafiz M.N. Iqbal +5 more
TL;DR: An effort has been made to highlight the importance of marine algae as naturally inspired biosorbents and their role in biosorption.
Journal ArticleDOI
Biochar as both electron donor and electron shuttle for the reduction transformation of Cr(VI) during its sorption.
TL;DR: The results indicated that biochar could act as both electron donor and electron shuttle for the reduction of Cr( VI) during the sorption process, making it an alternative for removal of toxic Cr(VI) from wastewaters.

Journal ArticleDOI
Microbial heavy-metal resistance
TL;DR: This review describes the workings of known metal-resistance systems in microorganisms and the transport of the 17 most important (heavy metal) elements is compared.
Journal ArticleDOI
Microbial resistance to metals in the environment.
TL;DR: Six metal resistance mechanisms exist: exclusion by permeability barrier, intra- and extra-cellular sequestration, active transport efflux pumps, enzymatic detoxification, and reduction in the sensitivity of cellular targets to metal ions.

Bacterial resistances to toxic metal ions--a review.
TL;DR: Recently, isolated genes defective in the human hereditary diseases of copper metabolism, namely Menkes syndrome and Wilson's disease, encode P-type ATPases that are more similar to bacterial CadA than to other ATPases from eukaryotes.
