Adsorption Kinetics of Cu(II), Cr(III), and Ni(II) Ions from a Multicomponent Solution Using Synthetic Zeolite

Indira Šestan, Melisa Ahmetović & Selma Hasanović · International Research Journal of Pure and Applied Chemistry · 2025

Zeolites are particularly suitable adsorbents due to their pronounced ion-exchange capacity, high efficiency, stability, and the ability to be regenerated and reused multiple times. Their characteristic crystalline structure enables the exchange of sodium, potassium, calcium, and...
