In recent decades, environmental pollution has become a significant problem for human health and impact. The high accumulation of heavy metals in waters soils from different sources was conducted finding efficient environmentally friendly treatment methods materials their removal, respectively. Natural zeolites have found wide-ranging applications remediation protection, considering various modification designed to enhance the natural zeolites' adsorptive or ion-exchange capabilities increased efficiency. This paper briefly consolidates scientific literature related main characteristics modified zeolites, advantages limitations applying remediation, summarizes methodologies applied order improve properties. Their application removing water systems is also comprehensively discussed. review highlights excellent potential be used after specific as sustainable green material solve numerous issues.

Abstract This study is intended to find the effect of natural zeolite pre-treatment as an adsorbent for Cr(VI). Activated will be made through physical and chemical activation by NaOH 1M. get irradiation treatment gamma rays with variations 0, 100, 200, 300, 400, 500 kGy dosage. Characterization was obtained iodine number changes composition structure used XRF, XRD, SEM, FTIR, specific surface area based on number. The best conditions pretreatment were then Cr(VI) batch system isotherm thermodynamics adsorption. highest activated a gamma-irradiated dose 300 which 329,439 m 2 / g . adsorption process at three different temperature that fit Langmuir maximum capacity 12.183 mg/g showed exothermic enthalpy entropy values - 13.994 kJ/mol -0.070 respectively.
