Natural and synthetic zeolites perspectives for soil remediation

Barbora Hudcová et al. recently published a paper focused on zinc binding properties onto natural and synthetic zeolites. The study investigated the adsorption mechanisms of Zn(II) on natural, synthetic, and perlite by-product zeolites under different conditions including laboratory solutions, extracted soil solutions and real metal-rich soils. The adsorbed amount and strength of binding decreased in the order of synthetic > perlite by-product > natural zeolite showing significant influence of the zeolitic framework and related properties. The experiments in soils showed reversible (weaker) binding of Zn on natural zeolite and, conversely, a significant influence of irreversible (stronger) binding on both synthetic zeolites. This study also provided information on the main disadvantages and perspectives of the application of zeolites in remediation technologies.
