摘　　要：利用水溶液法合成的聚丙烯酸-丙烯酰胺吸水树脂对4种不同类型染料废水进行吸附。研究结果显示,该树脂对染料的吸附率由高到低的顺序依次为:孔雀石绿、次甲基蓝、中性红和碱性品红;相对于碱性品红和中性红,该树脂对碱性染料孔雀石绿、次甲基蓝的吸附效果更好,吸附率可达95%;在10mg/L的人工染料废水溶液中树脂对染料的吸附率在pH 6.0时最高,对孔雀石绿、次甲基蓝、中性红和碱性品红的吸附量分别为47.94,45.65,19.18,10.39mg/g。本研究为树脂对工业染料废水的吸附处理提供理论参考。A poly （acrylic acid-acrylamide） superabsorbent resin was used to treat four different dye wastewaters by adsorption. The results showed that the order of the adsorption rate of the resin to four dyes from high to low was as fol- lows：Malachite Green, Methylene Blue, Neutral Red and Basic Fuchsin. Malachite Green and Methylene Blue revealed a stronger dye removal ability than Neutral Red and Basic Fuchsin, with a removal rate up to 95 ~. The capability of the resin for the removal of wastewaters was maximum at pH 6.0 under initial concentration of 10 mgL-1. The maximum adsorption capacity ofthe resin was 47. 94,45.65,19.18, and 10. 39 mg/g for Malachite Green,Methylene Blue, Neutral Red and Basic Fuchsin, respectively. The research provided theoretical reference for the treatment of dye waste/waste water.
