Research Progress on the Removal of Mercury from Wastewater Using Zeolite Based Environmental Mineral Materials

Mercury is a highly toxic heavy metal that is not only difficult to degrade in aquatic environments, but also exhibits significant bioaccumulation through the food chain, ultimately posing a serious threat to human health. Adsorption method has become one of the effective ways to treat mercury containing wastewater due to its advantages of easy operation, high treatment efficiency, and low cost. Environmental mineral materials have the characteristics of wide sources, environmental friendliness, large specific surface area, and strong ion exchange ability, and have shown good application potential in the field of mercury containing wastewater treatment. Among them, zeolite based environmental mineral materials have been widely studied. This article systematically reviews the research status and development of several common environmental mineral materials such as zeolites in the treatment of mercury containing wastewater, including commonly used modification methods, modification principles, and the main factors affecting the adsorption process. The aim is to provide reference for the preparation of mercury containing wastewater treatment materials in the future and provide new ideas for related research work.
