THE USE OF METAKAOLIN-BASED GEOPOLYMERS FOR WASTEWATER TREATMENT

Abstract

The article presents methods for the purification and removal of cadmium and lead ions using materials based on metakaolin, cement, Kokshetau clay, and geopolymers. The adsorption properties were studied during the preparation of a model solution using cadmium and lead salts. The efficiency of the purification process was evaluated using infrared (IR) spectroscopy and atomic emission spectroscopy methods. The results demonstrate that geopolymers serve as an effective and eco-friendly alternative for treating wastewater contaminated with heavy metals. The findings highlight the potential of geopolymers as an innovative and sustainable approach to wastewater management, reducing environmental pollution and associated health risks. The results of the work showed the possibility of using Geopolymers as an environmentally effective and alternative method for treating wastewater contaminated with heavy metals.
