Application Of High-Performance Activated Carbon Adsorption Process In Degradation Of Heavy Metal Pollution Of Soil

Heavy metal pollution of soil not only causes great damage to the ecosystem, but also accumulates in the human body with the food chain, endangering human health. Highperformance activated carbon has a strong adsorption capacity, and its special structural characteristics are of great significance for the degradation of heavy metals in soil. By introducing the structural characteristics of high-performance activated carbon, this study points out that activated carbon has rich pore structure and is widely used in soil remediation. This paper also introduces how to improve the adsorption capacity of activated carbon for heavy metals of soil from three aspects of oxidation modification, reduction modification and metal loading modification, so as to improve the efficiency of controlling heavy metal pollution of soil. Response surface model was used to analyze the activated carbon preparation temperature, activation time and soil pH. The results showed that the response surface model had significant difference, and each index had a significant influence on the adsorption efficiency of activated carbon for heavy metals of soil. The quadratic multiple regression equation was R=81.08+0.7875A-0.125B+4.39C+0.425AB+ 0.7AC+0.325BC-3.74A(2)-2.22B(2)-3.14C(2).
