“…Precipitation and adsorption processes are economic and effective, but only efficient when the Cr(VI) concentration is relatively high (Abyaneh and Fazaelipoor 2016 ; Hokkanen et al 2016 ). Ion exchange is high-efficiency in general, but it is rather expensive to maintain and operate (Ali et al 2015 ). Some even cause secondary pollution.…”

“…Ali et al studied the removal of Cr(VI) using iron nanoparticles supported on a porous cation-exchange resin. 15 The process involves a separate procedure for the preparation of iron nanoparticles and their dispersion on a polymer support. In another approach, Pd supported on amine-functionalized SiO 2 yielded efficient conversion of Cr(VI).…”

“…6,9 Reduction of Cr(VI) to Cr(III) is reported to be achieved chemically, biologically, and photochemically. 1015 Biotreatments are considered to be cost-effective and environmentally friendly; however, such methods are generally slow. Considering the chemical route, which is generally a viable method, most of the recent protocols involve costly chemicals such as Pd- and Pt-containing systems, complex catalyst preparation steps, and long duration.…”

“…Cr(VI) species are about 100 times more toxic than Cr(III) species, because Cr(VI) is easily adsorbed in the stomach and accumulated in the kidney and liver (Chen et al, 2018). Alternatively, low Cr(III) levels are essential to mammalian life (Ali et al, 2015). e World Health Organization (WHO) has stipulated the maximum concentration of Cr(VI) in drinking water as 0.05 mg L −1 (World Health Organization, 2017).…”
