摘　　要：大孔膦酸树脂吸附钇的研究舒增年熊春华（丽水师范专科学校化学系浙江３２３０００）林峰（杭州大学化学系杭州３１００２８）关键词大孔膦酸树脂钇吸附机理中图分类号Ｏ６１４．３２２本文在ＨＡｃ－ＮａＡｃ体系中，研究了树脂吸附钇的性能及其机理，获得了诸多的结果，...The adsorption behariour and mechanism of Y(Ⅲ) ion the macroporous phosphonic acid resin are reported.The macroporous phosphonic acid resin has a good adsorption ability for Y(Ⅲ) ion HAc-NaAc medium at pH 5.0.The yttrium ion adsorbed on the macroporous phosphonic acid resin can be eluted by 0.60mol·l -1 NaCl+0.20mol·l -1 HCl aqueous quantitatiely.The saturated static adsorption capacity is 159.8mg/g resin,Coordination molar ration of functional group to Y(Ⅲ) is 3∶1. The basic adsorption parameters and mechanism of macroporous phosphonic acid resin for yttrium ion were determined by chemical analysis and IR spectroctry.
