【摘要】 本文主要进行了柳江河沉积物对 PO43 -的吸附实验研究 ,得到如下结论 :( 1 )在实验浓度范围内柳江河沉积物对 PO43 -的吸附量随 PO43 -的浓度的增大而增大 ,呈线性关系。 ( 2 ) p H值对吸附作用的影响较大 ,在p H值 3～ 5之间出现吸附百分率的最大峰值更多还原

【Abstract】 Exchange adsorption experiment of the sediments from Liujiang River for PO 4 3- were done.The results were as follows:(1) The exchange adsorption isotherms of sediment for PO 4 3- was a line.(2) exchange adsorption abilities of the sediments for PO 4 3- vary greatly with defferent pH.There was "seak" when pH was between 3 and 5.更多还原
