One of the techniques for the removal of Cu 2+ from water and wastewaters is adsorption
and special attention has been focused on biosorption. Compared to the conventional …

Cellulose is the most abundant biomass resource in the world. It can be transferred to
various water soluble derivatives, biochemicals, and materials. In the second half of the 20th …

Watermelon peel residues were used to produce a new biochar by dehydration method. The
new biochar has undergone two methods of chemical modification and the effect of this …

This study evaluated the application and efficiency of modified activated carbon in the
removal of copper (Cu) from synthetic aquatic samples. The surface of activated carbon …

The bioadsorbent C1, which is a chitosan derivative prepared in a one-step synthesis, was
successfully used to adsorb Cr (VI) and Cu (II) simultaneously. Here, for the first time the …

A bioadsorbent (CEDA) capable of adsorbing As (V) and Cu (II) simultaneously was
prepared by tosylation of microcrystalline cellulose (MC) and nucleophilic substitution of the …

Proflavine sulphate dye is acknowledged as a hazardous substance detrimental to both
human health and the environment. Consequently, our primary objective was to put forth a …

In the third part of this series of studies, the adsorption of the basic textile dyes auramine-O
(AO) and safranin-T (ST) on a carboxylated cellulose derivative (CTA) were evaluated in …

Cellulose beads consist of natural polysaccharide fibers and are widely used in various
industrial materials and applications. Nevertheless, the key challenge is how to effectively …

This study describes the chemical modification of chitosan to produce a novel
bifunctionalized adsorbent material (C4) for the removal of Cu 2+ and oxyanions of Cr 6+ …
