摘要
采用静态吸附法研究了聚丙烯酰胺(PAM)在黄土、盐碱土上的吸附行为,考查了不同液固比、吸附时间对土壤吸附量的影响,得出了PAM在土壤上的吸附等温线。结果表明,PAM在土壤上有很强的吸附亲合力,在盐碱土、黄土上的吸附等温线都符合Langmuir吸附模式,在相同实验条件下,盐碱土饱和吸附量比黄土饱和吸附量大。
Experimental runs were performed to study the adsorption of polyacrylamide （PAM） on soil （loess and saline alkali types）, The adsorptive capacity of soil for PAM increased with the contact time and/or the liquid/ solid ratio. The adsorption equilibrium test data were well correlated by the Langmuir adsorption model, The saline alkali soil exhibited a higher PAM capacity than the loess soil over the entire concentration range （up to 1 200 mg/L） under all test conditions,
