重金属汞在中国两种典型土壤中的吸附解吸特性研究的开题报告 摘要： 本研究的主要目的是探究重金属汞在中国两种典型土壤中的吸附解吸特性。通过实验方法，研究土壤的性质、PH值、汞的初始浓度等因素对汞的吸附解吸特性的影响，探讨该土壤在重金属汞污染治理中的应用价值。 本研究将选取两种典型土壤，即红壤和黑土，并结合文献综述，对汞的吸附解吸特性进行深入探讨。具体研究内容包括：1）采集不同种类土壤的样品，并对其进行土壤物理化学性质分析；2）制备各种浓度的汞溶液，并设置不同实验组进行汞的吸附和解吸实验，并测定汞的吸附解吸量；3）根据实验结果进行数据处理和分析，得出土壤中汞的吸附解吸特性。 通过本研究所得结论，可以为重金属汞污染的治理提供理论与实验支持，也为土壤环境的保护与管理提供参考。 关键词：重金属汞；土壤；吸附解吸特性；污染治理 Abstract: The main objective of this study is to investigate the adsorption-desorption characteristics of heavy metal mercury in two typical soils in China. Through experimental methods, the effects of soil properties, pH values, initial mercury concentrations and other factors on the adsorption-desorption characteristics of mercury will be studied, and the application value of this soil in heavy metal mercury pollution control will be explored. This study will select two typical soils, red soil and black soil, and conduct a comprehensive study on the adsorption-desorption characteristics of mercury in combination with literature review. The specific research contents include: 1) collecting soil samples of different types, and analyzing their physical and chemical properties; 2) preparing mercury solutions of various concentrations, setting different experimental groups to carry out mercury adsorption and desorption experiments, and measuring mercury adsorption-desorption amounts; 3) processing and analyzing the data according to the experimental results, and obtaining the adsorption-desorption characteristics of mercury in the soil. The conclusions obtained from this study can provide theoretical and experimental support for the control of heavy metal mercury pollution, as well as reference for the protection and management of soil environment.
