In recent era, with increasing heavy metal pollution, several sorbents are used to remove
heavy metals from environment. Application of chemical adsorbents and biosorbents for …

In this study, the biosorption mechanisms of methylene blue (MB) and Cr (III) onto pomelo
peel collected from our local fruits are investigated by combining experimental analysis with …

PAMAM grafted chitosan as biocompatible adsorbent was synthesized through Michael
addition of methyl acrylate followed by amidation of ethylenediamine on the chitosan …

A novel adsorbent derived from grapefruit peel (GP) based biochar (GPBC) was synthesized
by combined carbonization of GP and subsequent activation by GP extracts. Compared to …

Biochar derived from co-pyrolysis of sewage sludge and calcium sulfate was used to remove
Cd (II) from aqueous solution. The results showed that the Cd (Ⅱ) adsorption better followed …

Three low-cost adsorbents (purified raw attapulgite (A-ATP), high-temperature-calcined
attapulgite (T-ATP), and hydrothermal loading of MgO (MgO-ATP)) were prepared as …

Efficient removal of Cd (II) and Pb (II) from contaminated water is considered a fundamental
point of view. Synthetic hydrogel biopolymers based on chitosan and alginate (cost-effective …

The activated biochar derived from pomelo peel waste (PPAB) was prepared using pomelo
peel (PP) wastes as the raw materials via chemical activation with phosphoric acid (H 3 PO …

The sorption properties of a functionalized magnetic chitosan sorbent have been
investigated for the recovery of Ni (II) and Pb (II) from aqueous solutions. This material was …

The last few decades have seen a dramatic increase in heavy metal ions in industrial
wastewater, especially Cr 6+ and Co 2+ ions, which have been shown to adversely affect …
