The role of clay minerals as an absorption for environmental issues

Clays are the most abundant materials in nature and soil, which have many applications. Clays are very small particles and are the connection between plants and soil, which have the greatest impact on humans and the environment. Now, the world today is involved in pollution and pollutants, and it is clear that pollution occurs when the number of pollutants entering is more than the environment's capacity and the environment cannot self-heal, as a result, it can have negative effects on the life of creatures and humans. Consequently, clay particles can be used as an agent to remove pollutants due to ease, availability, cheap price, abundance, low permeability and chemical stabilization. The most important application of clay minerals is related to their absorption capability, which turns them into cheap and effective absorbents. For example, bentonite has a specific surface area and a high absorption capacity compared to kaolin, and can be used in water and wastewater treatment. In addition to environmental applications, clays have also been used in medical science and the preparation of cosmetic and health products; Like the effect of kaolinites in skin diseases. In this research, an attempt has been made to collect a collection of the effects of clay minerals in environmental so that the value of clay mineral would be better realized in nature
