摘要
Abstract
The adsorption of polyacrylamide(PAM) on the black soil was studied by means of static adsorption method. The effects of static adsorption time on the capacity of PAM adsorption on the soll were examined and the adsorption isotherms of PAM on the soil were measured. Moreover, the desorption behavior of PAM on the black soil was also studied. The impact of shaken desorption time, mass ratio of solid/liquid, temperature and pH on the desorption of PAM on the black soil was analyzed. The results show that the adsorption isotherms are consistent with Langmuir model and the PAM saturated adsorptive capacity on black soil is 1.17 mg/g. PAM has a high adsorptive affinity on the black soil. The maximum desorption capacity on the black soil shares only 25% of the whole under the experimental conditions.关键词
