Web26 sep. 2024 · (b) Schematic representation of ion exchange process after inorganic NaCl salt treatment by synthetic zeolite A-4. It seems that Na + is more effective in electrical property and ion size than Ca 2+ for the cation adsorption of ammonium. Also additional Cl − ions seem to help attracting ammonium cation to ion exchange. WebDue to their ion-exchange capacities, many natural zeolites are effective carriers of herbicides, fungicides, and pesticides. ‘ZSM 5’ zeolite (or MFI type, a synthesized zeolite), a hydrophobic solid, was found to adsorb atrazine better when organics were present in the zeolite’ compartmentalized intra-crystalline void space [85,86].
