摘　　要：对柳江河沿岸土壤对河水中主要污染物质磷酸根进行了吸附实验研究,得到如下结论:(1)在实验浓度范围内柳江河沿岸土壤对磷酸根的吸附量随磷酸根的浓度的增大而增大,呈线性关系。(2)pH值对吸附作用有较大影响,在pH值4～7之间出现吸附百分率的最大峰值。An experiment of exchange adsorption of phosphate by soil along the Liujiang River showed that within the range of phosphate concentrations in the experiment, adsorption of phosphate by the soil appeared in a positive linear correlation with phosphate concentration and that pH had a great influence on adsorption, which reached its maximum within a pH range of 4～7. 
