摘要
本文研究了HDEHP(P204)在非晶型氧化铁表面上的吸附。P204的吸附度是溶液pH的函数,在温度298K时于pH3.05—4.15达最大值,对应着Fe(Ⅲ)—H_2O系中FeOH^(2+)、Fe(OH)_2^+、Fe_2(OH)_2^(4+)的稳定存在区域,并与温度,共存阴离子浓度和沉淀物表面积,表面电荷密度相关。
The factors affecting an adsorption of HDEHP by amorphous iron hydroxide have been investigated Adsorptivity of HDEHP was found to be a function of pH, temperature, concentration of SO_4^(2-), surface area and charge density of the iron hydroxide, and went throngh a maxium at pH 3.04—4.15, corresponding to the stability region for FeOH^(2+), Fe(OH)_2^+ and Fe_2(OH)_2^(4+) in the Fe(111) -H_2O system (298K).
