Zeolites play a significant role in many industrial processes, including adsorption, exchange, and catalysis, related to their large porous structure and retention properties. The purpose of the study is to value natural zeolites like microrous charge. Here, for selective ion separation, we mixed a biodegradable polymer (polypropylene PP) with varied ratios of zeolite rock deposits. Natural zeolite is extracted from a rock in the Bejaia region of Tinebdar, Algeria. Different physical-chemical techniques, including XRD, MEB, FTIR, and elemental analysis , have been used to confirm the structure and morphology of these deposits. The synthetic membranes are employed as filters to remove Co2+, Ni2+, Cu2+, and Pb2+ ions from aqueous solutions. The atomic absorption technique (AAS) was used to examine the filtrates that were collected. The findings indicate the presence of selective retention for the ions under consideration. The retention increases with zeolite concentration, and the highest retention was obtained in the PP polymer-based zeolite, with an ion-selective retention of about 80%.
