A novel Turkish natural zeolite (clinoptilolite) treated with hydrogen peroxide for Ni²⁺ions removal from aqueous solutions

Critical Review on Zeolite Clinoptilolite Safety and Medical Applications in vivo

“…but also by the material composition and cation affinity properties. In a recent article, Turkish clinoptilolite was activated with hydrogen peroxide, which acts as a weak acid, to improve Ni 2+ ions removal from aqueous solutions ( Çanli and Abali, 2016 ). The authors show changes on the clinoptilolite surface upon activation that resulted in an improved Ni-ions absorption.…”

“…Enzymes are deactivated during modification. Clinoptilolite can react with hydrogen peroxide ( Canli and Abali, 2016 ), similar to other silica particles, and, in such situations, oxidative stress is induced either through the breakdown of hydrogen peroxides to hydroxyl radicals or through the breakdown of hydrogen peroxides and production of the hydroperoxyl radicals ( Rochette and Vergely, 2008 ). Therefore, it is possible that the contact between clinoptilolite and tumor cells with increased hydrogen peroxide concentrations induces formation of free radicals; therefore, increases in the oxidative burden occur in tumor cells, which consequently die.…”

Study of the Antibacterial Capacity of a Biomaterial of Zeolites Saturated with Copper Ions (Cu2+) and Supported with Copper Oxide (CuO) Nanoparticles

“…The incorporation of metallic nanostructures with bactericidal properties can provide solutions in human medicine [ 1 ]. The diversity of applications is due, specifically, to the porosity of this material, which has a structure with negatively charged cavities that make it a striking material due to the exchange of monovalent and divalent ions, the presence of hydroxyl groups and water molecules [ 2 ], as well as the lodging of other molecules in their cavities, such as ammonia and nitrates [ 3 ].…”
