乌鲁木齐地区土壤对SO4^=的吸附动力学研究

Dynamic Study of SO_4￣= Absorbed by Soil in Urumqi

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．

Dynamics of SO4 absorbed by soil in Urumqi was studied. Experimental results fit mathematical model of Breundlich and Temkin isothermal absorption. Absorption processes of SO4 absorbed by soil consist of fast and slow reactions. Its regular can be described by dynamic equation of dual constant and Elorich and fit reactive law of complicated and multipole dynamics.
