Heavy metal pollution is a serious problem all over the world. Their consumption has become an integral part of the industrial sector due to the needs of the society. Heavy metals are one of the most persistent pollutants in wastewater. Their entry into wastewater causes various types of damage to the environment and living organisms. It is important to properly assess the risks associated with metal toxicity in order to create a healthy environment for living organisms. Natural mordeniteis less studied among other cleanings of waters, but has a special place due to its unique adsorption and ion-exchange properties. The high content of mordenite allows us to use its wide application, since in our country there is no synthetic zeolite production and their purchase is quite expensive. Therefore, in reality in Georgia, the use of natural mordenite in environmental protection is of great importance. The goal of our research is to study the adsorption and ion exchange of some particularly toxic heavy metals using natural and modified mordenite.
