چکیده مقاله
The remediation of wastewater contaminated with heavy metal ions using natural zeolite is a well established technique in environmental protection However, the practical effectiveness of treatment processes is often limited by employing natural zeolite This study proposes an innovative method for fabricating an efficient adsorbent from natural zeolite to treat tannery waste water containing Cr3 Structural modification of starting material was achieved using a mixture of aluminum and sodium hydroxides, which facilitated the hydrothermal conversion of precursor into nano porous hydroxysodalite The production of this low silica zeolite via the hydrothermal method is influenced by both aging time and crystallization duration The powder derived from the precursor, after an aging period of 16 h, demonstrated Cr3 adsorption efficiency comparable to that of commercially available natural zeolite Furthermore, a crystallization period of 16 h was found to be necessary for fabrication of an adsorbent with sufficient efficiency Overall, the proposed process is crucial for the utilization of hazardous effluents and offers practical insights into the fabrication of hydroxysodalite, representing a cost effective and sustainable approach
