Abstract
Abstract Pollution by heavy metals has become a problem that needs to be solved urgently. Therefore, the development of new efficient adsorbents to treat this pollution is of great importance. Due to their excellent adsorption properties and good biodegradability, natural polymeric materials are potential problem solvers. This study reports on the production and application of polypropylene glycol modified chitosan composites (PMC). The PMC composite material has many functional groups (–OH and –NH2). Its maximum adsorption capacity for Cu(II) is 661.8 mg g–1. The corresponding adsorption studies, including the effects of pH, contact time and amount of adsorbent, showed that the PMC composite has potential application value.
