Removal of toxic heavy metals from polluted water bodies is imperative for health and environmental protection.
To this end, chemical precipitation, chelate precipitation (flocculation), ion exchange, electrochemical, flotation, advanced oxidation, and membrane separation methods have been developed to address heavy metals, but no universal and effective treatment methods have been found so far.
The use of natural minerals to treat pollution and repair the environment is based on making full use of the laws of nature, reflecting the characteristics of natural self-purification.

Clay minerals have been used as excellent adsorbents due to the presence of different types of active sites on their surfaces, such as ion exchange sites, Lewis acid sites, and Bronsted sites.
The key to adsorption technology is the preparation of environmentally friendly, cheap, and efficient adsorbents.
Modified natural and synthetic clays such as kaolin, bentonite, montmorillonite, silver mica, and attapulgite are the most widely used clays for the preparation of high-performance nanocomposites.
This article mainly discusses advances in clay minerals and their derivatives for treating heavy metal effluent.
