“…Clinoptilolite showed the weakest performance among the adsorbents; however, the Na-CLP showed the best adsorption for Cs, but less so for Sr, Co and Mn ions. Adsorption of 103 Ru, Co 2+ and Ni 2+ on natural and modified CLP (NH 4 + form) was reported from nuclear wastewater (Faghihian, 2011; Malekpour et al , 2011). The selectivity of zeolite was greater for Co 2+ than Ni 2+ .…”

Iran has significant deposits of high-purity natural zeolites. Many Iranian scholars conduct scientific research on porous materials, from natural and synthetic zeolites to metal organic framework materials. Iranian zeolite deposits and associated research are reviewed here. Various industrial applications of natural zeolites, from agriculture to animal husbandry to the construction industry and beyond are discussed here.

“…The value of standard Gibbs free energy change calculated at 20˚C was found to be −20.46 kJ/mol for GAC and −16.01 kJ/mol in case of NZM. The negative sign for ΔG 0 indicates that the system reached a more stable energy level after ion exchange and the spontaneous nature of nitrate adsorption on the GAC/NZM [36,37].…”

A B S T R A C TThis paper focuses on a comparative study regarding the performance of natural zeolite from Mirşid (NZM) and granular activated carbon (GAC), respectively, for treatment process of contaminated groundwater from Cȃpuş, Cluj region for nitrate removal. The effect of pH, conductivity, contact time, and nitrate concentration have been studied. The Langmuir and Freundlich models were used to fit the experimental data and these showed good correlations with the Freundlich model, providing a better description of the equilibrium (higher R 2 value). Textural analysis was employed in order to determine the specific surface area, and pore size distribution of the used activated carbon and natural zeolite. The adsorbents (GAC and NZM) were characterized by using Fourier transform infrared spectroscopy and x-ray powder diffraction.
