摘要
本文采用等温吸附法研究了安徽省 1 6种土壤对硅的吸附作用 ,研究了三种 pH值条件下土壤对硅吸附特征 ,结果表明 :土壤对硅的吸附与土壤活性铁、活性铝含量呈极明显正相关 ,相关系数分别为 0 .85 72和 0 .6776。在加入硅溶液pH值 3- 9范围内 ,平衡液硅浓度随溶液
The adsorption of silicon on sixteen kinds of soils from different parent materials and effect of pH on the status of silicon adsorption on three kinds of soils were studied by way of isothermal adsorption curves.The results showed that the status of silicon adsorption and active Fe active Al content were very significant positive correlation.The concentration of silicon in balanced solution decrease when pH increase.
