Recent progress, synthesis, and application of chitosan-decorated magnetic nanocomposites in remediation of dye-laden wastewaters

Abstract

Over the past several decades, the disposal of dyes from the industrial manufacturing sector has had an inadvertent impact on water ecology as polluted water bodies with these hazardous dyes...

A review on environmental chemodynamics, isothermal, kinetics, and thermodynamics modeling for the adsorptive removal of Cr(vi) from the industrial effluent using magnetic nanoparticles as a bio-sorbent

“…Notably, the winning feature of magnetic bio-adsorbents as compared to commercial adsorbents and bio-adsorbents is their regeneration capability. 15 Using bio-adsorbents to remove Cr( vi ) results in poor adsorption efficiency and poor chemical resistance, which have limited their use as effective sorbents. The present study was conducted to review the Cr( vi ) elimination from industrial effluent using magnetic particles as a bio-adsorbent, focusing on three primary sources of biomaterial: potato starch, chitosan, and biochar.…”

Excellent regeneration, easy separation and high capacity of 3D chitosan–melamine sponge composites for anionic dye removal

“…3 Dyeing wastewater is a pollutant causing great harm to the environment; in addition to its toxicity, carcinogenicity, mutagenicity and teratogenicity, [4][5][6] the key problem is that it will impart color to water bodies. 7,8 Considering the difficult degradation of dyes, 9 developing methods for the removal of dyes from dyeing wastewater is particularly important.…”
