Heavy metal pollution has become one of the most severe environmental issues. Adsorption
is an effective method for removing heavy metals from aquatic environments. The adsorption …

In modern society, the bulk production of new chemicals, huge consumption, and the
discharge of micropollutants into the environment are unavoidable events. Practically …

Biochar that is directly obtained by pyrolysis exhibits a low adsorption efficiency;
furthermore, the process of recycling adsorbents is ineffective. To solve these problems …

Heavy metals and azo dyes caused huge harm to the aqueous system and human health. A
magnetic chitosan/polyethyleneimine embedded hydrophobic sodium alginate composite …

The use of biosorption as a strategy for lowering the amount of pollution caused by heavy
metals is particularly encouraging. In this investigation, a low-cost and efficient biosorbent …

Heavy metals and organic pollutants were universally co-existing in water, except for
dissociated pollutants, their complexes have caused huge damage to the environment and …

Biomass-based humic acid (BHA), which is rich in functional groups, was obtained from
waste rice straw by a one-step hydrothermal process. The BHA was then co-precipitated …

The strategy, called purifying wastewater with waste materials (PWWM), can simultaneously
improve the secondary utilization of industrial waste materials and in turn, reduce …

This study focussed on the development of a novel and efficient adsorbent derived from
polyvinyl alcohol-modified chitosan composite for the removal of Cu+ 2, Ni+ 2, and Zn+ 2 …

Extracting functional materials from industrial waste residues to absorb organic dyes can
maximize waste reuse and minimize water pollution. However, the extraordinarily low …
