Chromium exists mainly in two forms in environmental matrices, namely, the hexavalent (Cr
(VI)) and trivalent (Cr (III)) chromium. While Cr (III) is a micronutrient, Cr (VI) is a known …

The huge quantities of textile industry effluents with high concentrations of heavy metals are
associated with the water pollution. Among the conventional technologies currently in use …

Abstract Nitrate (NO 3−) and chromium (Cr (VI)) ions from contaminated aqueous solutions
were successfully adsorbed onto functionalized cocoa shell (ECAB, an agricultural waste …

Chromium is a toxic heavy metal prevalent in higher levels in aqueous matrices owing to
industrial applications. Whilst being a key player in industries, the environmental issues …

Several conventional techniques for heavy metals decontamination for instance ion
exchange, evaporation, precipitation and electroplating have been utilized in preceding …

The removal of toxic heavy metals from wastewater through the use of novel adsorbents is
expensive. The challenge arises after the heavy metal is removed by the adsorbent, and the …

Iron ions were doped on the rice husk for adsorption-cum-reduction of lethal Cr (VI) to less
toxic and partially soluble Cr (III). Energy dispersive X-ray analysis and X-ray photoelectric …

Due to the high cost associated with the treatment of effluents containing heavy metals in the
environment, the continuous untreated release of effluent containing chromium from textile …

Macadamia activated carbon (MAC) was impregnated with different concentrations of
sulphuric or phosphoric or nitric acid ranging from 20 to 60% v/v and heated in a muffle …

This study deals with the elimination of hexavalent chromium from simulated solution using
Acacia auriculiformis shells and its different modified forms as potent biosorbents. The raw …
