Biowaste‐derived substances isolated from green compost (BBS‐GC) are environmentally friendly reactants similar to humic substances, which contain multiple functionalities, that are suitable for adsorbing different kinds of pollutants in wastewater. Herein, sodium alginate (derived from brown algae) cross‐linked with both Ca2+ ions and BBS‐GC in the form of hydrogels and dried films are proposed as...
Magnetic chitosan composite (MCC) made by chitosan matrix embedding magnetite/maghemite were developed for the removal of toxic Cu(II), Pb(II), and Ni(II) from water. Thermogravimetric (TGA) and Zeta potential analyses showed that MCC contains ca. 50 wt % of chitosan and presents a value of isoelectric point (pHIEP) around 8-8.5. The magnetization curve revealed a saturation magnetization of 12 emu...
