邻硝基苯酚在黄河水体的吸附作用研究

Study on the Adsorption of o-Nitrophenol in the Yellow River

用批量平衡法研究了黄河水体沉积物对邻硝基苯酚的吸附作用 .结果表明 :吸附等温线符合Freundlich方程 ,通过回归分析 ,得出等温方程为Cs=0 4 70 2×C0 74 98eq .因指数项常数小于 1。

The adsorption of the sediments on o \|nitrophenol was studied in the Yellow River by using batch equilibrium method. The results show that adsorption isotherm was fitted to the Freundlich equation. The equation was obtained with the least square method that is C s=0 4072× C 0 7498 eq .Because of a <1 the adsorption of o nitrophenol on the sediments isn't direct proportion increased with concentration of o nitrophenol in the solution.
