Abstract

This study focuses on investigating the thermodynamic parameters of an ion exchanger synthesized using chlorinated polypropylene with polyethylene polyamines. The ion exchanger, derived from chlorinated polypropylene, demonstrates full compliance with chemical resistance standards. The research involves the examination of isotherms governing the sorption process of Cu(II) and Ni(II) ions by the ion exchanger. These isotherms adhere to the Freundlich model, offering insights into the ion-exchange behavior of the material. Additionally, the study delves into the dynamic exchange capacity and desorption characteristics of the resulting ion exchanger in a granular state. These parameters are crucial for understanding the material's performance in practical applications, shedding light on its ability to efficiently exchange and release metal ions. By comprehensively analyzing the thermodynamic aspects and sorption behavior of the synthesized ion exchanger, this work contributes valuable knowledge to the field of ion exchange materials. The findings offer a basis for further optimization and application of such materials in various industrial processes, particularly in the removal of heavy metal ions from aqueous solutions.
