摘要: In the presented paper, sorption of copper(II) and zinc(II) in presence polyaspartic acid sodium salt on polystyrene ion exchangers from aqueous solutions was studied. This is an active, water soluble polyaminocarboxylate with multifunctional property profile. It a complexing agent new generation as it undergoes biodegradation thus being alternative for reagents EDTA or NTA type. On basis research, applicability gel macroporous anion different functional active groups, Lewatit MonoPlus M 500, 600, MP 500 well 64 62, determined by dynamic technique. Batch experiments were also carried out to determine factors affecting kinetics process.
