Application of Supramolecular Nano-Material Adsorbent in the Treatment of Heavy Metal Pollution in Acid Selenium-Rich Soils in South China

Abstract

In China, soil heavy metal pollution is becoming more and more serious, and supramolecular nanomaterial adsorbents are very effective in the treatment of heavy metal pollution in acid selenium-rich soil environments. Pollution control related research is essential. The purpose of this article is to solve the problem of pollution control of heavy metals in the acid selenium-rich soil environment in southern China. By understanding the existing methods of pollution control of heavy metals in the soil environment, especially the use of supramolecular nanomaterial adsorbents to control the pollution of heavy metals in the soil Methods and related principles, and then conducted a detailed investigation and research on the application of existing supramolecular nanomaterial adsorbents in the treatment of heavy metal pollution in acid selenium-rich soil environment. The research results show that the use of supramolecular nanomaterial adsorbents to treat heavy metal pollution in acid selenium-rich soil environment is very effective. The acid selenium-rich soil treated with supramolecular nanomaterial adsorbents not only reduces the exogenous selenium fertilizer The amount of application, but also reduces the food selenium caused by the application of exogenous selenium fertilizer, safety risks and environmental selenium poisoning caused by improper application of selenium fertilizer, verified by experiments, the quality of contaminated soil treated by supramolecular nanomaterial adsorbent The index increased by 15% and the crop harvest rate increased by 20%.
