摘要
研究了不同pH值下HPAM在膨润土上的吸附,发现不同pH值下HPAM在膨润土上的吸附量与其在溶液中的分子线团尺寸有关,HPAM在溶液中的分子线团尺寸愈大,其在膨润土上的吸附量愈小。
The adsorption of HPAM on bentonite at different pH value is studied . It is shown that the adsorption at different pH is related to the molecular size of HPAM . and the larger the molecular size , the lower adsorption on bentonite of HPAM .
