Despite the importance of chromium (Cr) in most anthropogenic activities, the subsequent
environmental adulteration is now a source of major concern. Cr occurs in numerous …

Heavy metals contamination has become a global environmental problem owing to
anthropogenic sources. They are considered a stern threat to humans, aquatic life, and …

In aqueous solutions, hexavalent chromium Cr (VI) was successfully removed by activated
carbon “Z. jujuba rubidium carbonate-activated carbon” obtained from waste lignocellulosic …

The usage of zeolites in wastewater treatment has been extended in the two recent
decades. This review investigates recent developments on the zeolite usage in the removal …

Nowadays, the existence of metal ions in the environment like chromium (VI) is of significant
worry because of its high toxicity to many life forms. Therefore, in this study, an inexpensive …

In this research, adsorption of chromium (VI) ions on wheat bran has been studied through
using batch adsorption techniques. The main objectives of this study are to 1) investigate the …

Three different biomass wastes (rice husk, sawdust, and municipal organic waste) were
thermally converted to value-added biochars at two pyrolytic temperatures of 300° C and …

Cr (VI) is one of the most toxic contaminants recognized as a carcinogenic and mutagenic
agent and needs complete removal from wastewater before disposal. In the present study, a …

The present study explored the kinetics, equilibrium and thermodynamics of amaranth (acid
