摘　　要：(1)喇嘛湾,薛家湾段和老牛湾段沉积物对硅的吸附包含快速吸附阶段(0~2h)与慢速吸附阶段(2~48h)。相同条件下,喇嘛湾段沉积物对硅的吸附能力大于薛家湾段与老牛湾段。(2)三段沉积物对硅的吸附速率方程符合Lagergren二级吸附速率方程,拟合相关系数R2均达到0.999以上。(1)The adsorption of silicon on sediments in Lamawan section,Xuejiawan section and Laoniuwan section of Yellow River consists of rapid adsorption(0~2 h)stage and slow adsorption(2~48 h).The silicon adsorption ability of Lamawan section sediment is larger than others in the same condition.(2)Silicon adsorption kinetics onto three sediments all followed second-order adsorption rate equation,and the linearly dependent coefficient of fitting are over 0.999.
