摘要:
为促进对砒砂岩的应用，治理沙漠化问题，选定砒砂岩、沙及二者不同比例复配土共7种材料，利用土壤胶体Zeta电位测定仪，测定了7种样品在不同pH条件下的Zeta电位。结果表明：（1）砒砂岩、沙两种材料随着pH的增大，Zeta电位绝对值逐渐增大。（2）相较于沙及不同比例复配土来说，砒砂岩的Zeta电位绝对值整体较大。（3）不同比例复配土的Zeta电位特性在不同pH条件下变化趋势略有不同。由此得出：砒砂岩、沙及二者不同比例复配土胶体在碱性环境下相对稳定，砒砂岩的胶体稳定性较其它几种材料相对要好，砒砂岩与沙复配比例为1∶2和1∶5时，在一定的pH条件下，其胶体稳定性基本接近砒砂岩，因此将砒砂岩和沙按照1∶2或1∶5进行复配，是解决沙漠化问题的一项有效措施。
Abstract:
In order to promote the utilization of sandstone and control the desertification,seven types of materials,including sandstone,sand and mixed soils with different proportions were selected.The soil colloid Zeta potential meter was used to determine the Zeta potential of all materials at different pH.The results showed that (1) With the increase of pH value,the absolute value of Zeta potential increases gradually in the sandstone and sandstone materials.(2) The absolute value of the Zeta potential of the sandstone is larger than that of the sand and the different proportions of the compound soil.(3) Zeta potential characteristics of different proportions of compound soils have slightly different trends under different pH conditions.It is concluded that the sandstone,sand,and soil colloids with different proportions are relatively stable under alkaline conditions.The colloidal stability of the sandstone was better than that of other materials,and the ratio of sandstone to sand was 1∶2 and 1∶5,the colloidal stability was close to that of the sandstone under certain pH conditions.Therefore,it is an effective measure to solve the desertification problem by reconstructing the sandstone and sand in accordance with 1∶2 or 1∶5.
