本文对乌鲁木齐土壤吸附ＳＯ４＝进行了动力学研究．实验结论与Ｆｒｅｕｎｄｌｉｃｈ和Ｔｅｍｋｉｎ等温吸附数学模型拟合较好．土壤对ＳＯ４＝吸附过程由快速反应和慢速反应两部分组成，其规律引用双常数方程和Ｅｌｏｒｉｃｈ等动力学方程描述．且符合反映吸附机制及复杂的多级动力学反应规律．
In this paper, kinetics of SO4 adsorption in soils of Urumqi was studied. The experimental results fit well with the Freundlich and Temkin Isothermal adsorption mathematical models. Soil SO 4 = adsorption process consists of rapid reaction and slow reaction of two parts, the law of reference double constant equation and Elorich other dynamic equations described. And in line with the adsorption mechanism and complex multi-level kinetic reaction law.
