本文对氨基膦酸型螯合纤维吸附Hg（Ⅱ）离子的特性进行了研究,考察了溶液平衡pH值对吸附百分率的影响,探讨了此螯合纤维对Hg（Ⅱ）离子的吸附选择性,结果表明:该螯合纤维对Hg（Ⅱ）离子的吸附基本符合Freundlich型等温方程式,并且具有较大的螯合容量和较快的吸附速度,在较低pH值下,对Hg（Ⅱ）离子具有较高的选择性。
In this paper, the adsorption properties of Hg (Ⅱ) ions by aminophosphonic acid chelating fiber were investigated. The effects of solution pH value on the adsorption percentage were investigated. The adsorption selectivity of Hg (Ⅱ) The results showed that the adsorption of Hg (Ⅱ) ion by the chelated fiber was basically consistent with the Freundlich isotherm equation and had a large chelating capacity and fast adsorption rate. Under the condition of low pH, the Hg (Ⅱ) ion With high selectivity.
