摘　　要：本文研究了不同温度下四种类型大孔吸附树脂内部有机残留物的溶出动力学。在常温下,S-8型树脂溶出的有机残留物主要有正己烷和正辛烷,NKA-9型树脂主要是正辛烷,AB-8型树脂和X-5型树脂无有机残留物溶出;在40℃条件下,S-8型树脂溶出的有机残留物正己烷和正辛烷溶出的速度和浓度明显增加,NKA-9型树脂的正辛烷溶出的速度和浓度明显增加,AB-8型树脂则出现了甲基丙烯酸甲酯、1,2-二氯乙烷和间二甲苯等新的有机残留物,而X-5型树脂仍未发现有机残留物。The dissolution kinetics of organic residues in four kinds of macroreticular resins were studied.The results showed that n-Hexan and Octane were found in S-8 macroporous resin at ambient temperature.Amounts of Octane were determined in NKA-9 macroporous resin at ambient temperature.There were no residues in the AB-8 macroporous resin and X-5 macroporous resin at ambient temperature.The dissolution rate and concentration of residues were increased in S-8 macroporous resin and NKA-9 macroporous resin at 40℃.At the same time,some new residues were found in the AB-8 macroporous resin at 40℃.
