| Abstract Scope |
Clinoptilolite is a natural zeolite mineral mostly utilized for its preeminent ion exchange and adsorption properties. Its large-scale specific surface area enables its surface functionalization for the removal of hazardous contaminants in water and wastewater. However, various pretreatment methods including acid incubation and/or heating during modifications impact its overall performance and accessible active sites which influence the dealumination. Therefore, understanding the dealumination concerning pretreatment methods is crucial for optimizing the ion exchange and adsorption of contaminants from modified clinoptilolite. It is observed that an extremely acidic pH aqueous environment exhibits high Al content. For example, an aqueous suspension of pH 2 extracted approximately 2 mg of Al species per gram of heated clinoptilolite grains and increased linearly with time. This study investigates the effects of pretreatment methods for characterizing the aluminum species extracted from the clinoptilolite framework by Atomic Absorption Spectroscopy to assess it as a water purification material. |
