两种高吸水性树脂对地表水及其中几种离子吸附性能的研究

Studies on the Adsorption Performance of Two Kinds of Resin with the High Water-Absorbin Quality on Surface Water and Several Kinds of Ions in the Water

用淀粉-聚丙烯酸型及聚丙烯酸型两种高吸水性树脂对地表水和水中几种离子的吸附进行了研究。结果表明：高吸水性树脂具有阳离子交换树脂的性质，对阳离子有较强的吸附能力，对阴离子的吸附能力较弱；吸附能力因吸水剂种类、离子性质及浓度而异。

Studies were conducted on the adsorption performance of the starch-polyacrylic-type and polyacrylic-type resin with the high water-absorbing quality on surface water and different ions in the water. Theresults demonstrate that the resin with the high water-absorbing quality possesses the property of canons exchanging resin and possesses the relatively strong capacity of adsorbing canons whereas its capacity of adsorblug anions is comparatively weak. Its adsorption capacity varies with the water-absorbing agent kinds, ionproperty and ion concentration.
