A Comprehensive Review of Natural and Surfactant Modified Zeolites and Their Applications

Abstract

The present review provides an overview of the fundamentals and diverse applications of zeolites as reported in recent literature. Zeolites are crystalline microporous oxide materials with well-defined pores of molecular dimensions within their structure. Natural zeolites have garnered significant attention for their extensive environmental remediation and restoration applications. They are utilized as effective cation exchangers for removing pollutants from industrial wastewater and radioactive contaminants from nuclear power plant waters. Additionally, zeolites exhibit capabilities in decomposing indoor air ozone and enhancing peroxide bleaching of thermal-mechanical pulp, contributing to air and water quality improvement efforts. The review also sheds light on biomedical applications that harness natural and synthetic zeolites, highlighting their potential in diverse medical contexts. Overall, this review encapsulates the multifaceted nature of zeolites and their significant contributions across environmental, industrial, and biomedical domains.
