Copper removal from industrial wastewater by hydrogel nanocomposite based on poly (acrylic acid) grafted onto kappa carrageenan

Hydrogel nanocomposite based on poly (acrylic acid) grafted onto kappa carrageenan was investigated to detoxify aqueous solutions contaminated with the regulated mycotoxin copper. The results reveal the adsorbents possess more accessible active sites and good dispersibility in water, exhibiting excellent performance for Cu2+. The results of adsorption behavior are followed the Langmuir model between the adsorbents and the Cu2+ ions. Furthermore, the adsorbents can be recovered easily with an external magnetic field, having higher remove efficiency after several times
