摘要
本文报道了大孔膦酸树脂对轴酰离子的吸附行为与机理．在ｐＨ＝３的ＨＡｃ－ＮａＡｃ体系中对ＵＯ有很好的吸附性，用５％的Ｎａ２ＣＯ３溶液定量解吸，测得静态吸附容量为４５０．６７ｍｐ／ｇ．用化学及红外光谱等方法，得到大孔膦酸树脂吸附铀酰离子的基本参数及其机理．
In this paper, the sorption behaviour and mechanism of uranyl ion onto the macroporous phosphonic acid resin are reported. The macroporous phosphonic acid resin has a good adsorption ability for uranyl ion in the HAc-NaAc medium at PH 3. 0. The uranyl ion adsorbed on the macroporous phosphonic acid resin can be eluted by 5% aqueous Na2CO3 quantitatively. The saturated static adsorption capacity is 450. 67 mg/g. The basic adsorption parameters and mechanism of macroporous phosphonic acid resin for uranyl ion were determined by chemical analysis and IR spectrometry.
