Preparation method and application of mercury-polluted soil molybdenum disulfide geopolymer composite material
The invention discloses a preparation method of a mercury-polluted soil molybdenum disulfide geopolymer composite material, which comprises the following steps: dissolving molybdenum disulfide nanosheets in water to obtain a molybdenum disulfide dispersion liquid, and carrying out pre-adsorption treatment on mercury-polluted soil by using the molybdenum disulfide dispersion liquid, and then solidifying and stabilizing the mercury-polluted soil subjected to pre-adsorption treatment in a geopolymer to obtain the molybdenum disulfide geopolymer composite material. The mercury-polluted soil molybdenum disulfide geopolymer composite material is applied to building materials. The coal ash-based geopolymer serves as a matrix, the molybdenum disulfide nanosheets are doped in the matrix, mercury soil pollutants can be effectively solidified and stabilized, the mercury leaching rate is lower, and the compressive strength of the material is improved.
本发明公开了一种汞污染土二硫化钼地质聚合物复合材料的制备方法，包括步骤：以二硫化钼纳米片溶于水得到二硫化钼分散液，由二硫化钼分散液对汞污染土进行预吸附处理，然后将预吸附处理后的汞污染土固化稳定化在地质聚合物中得到二硫化钼地质聚合物复合材料。本发明的汞污染土二硫化钼地质聚合物复合材料应用于建筑材料。本发明方法以粉煤灰基地质聚合物为基体，二硫化钼纳米片掺杂在基体中，可以有效的固化稳定化汞土污染物，具有更低的汞浸出率且提高了材料的抗压强度。
