污染物在土壤中的行为与土壤的表面化学特性密切相关,研究土壤的表面化学特性对于从微观领域了解污染物行为及其变化规律,采取有效措施减轻并消除土壤中污染物的危害,保护土壤环境和人体健康具有重要意义。为了增强土壤对有机污染物的吸附固定,国内外开始研究应用阳离子型表面 The behavior of pollutants in the soil is closely related to the surface chemical properties of the soil. Studying the surface chemical properties of the soil is important for understanding the behavior of pollutants and their changing rules from the microscopic level, taking effective measures to reduce and eliminate the hazards of pollutants in the soil, and protecting the soil Environmental and human health is of great importance. In order to enhance soil adsorption and fixation of organic pollutants, at home and abroad began to study the use of cationic surface
