摘　　要：由于缺乏具体的染料结构组成数据,使得无水染色废水精确回收利用十分困难,影响了超临界CO_(2)无水染色工艺的工业化推广。采用液质联用法对活性蓝M-2GE超临界CO_(2)无水染色废液进行分析,找到了最佳的流动相比例,并计算出超临界CO_(2)无水染色废液中可用染料占废液中总染料的70.15%。依据该试验数据能对活性蓝M-2GE超临界CO_(2)无水染色废液进行精确化重复利用,使超临界CO_(2)无水染色工业化成为可能。Due to the lack of specific data on the structure and composition of dyes,it is very difficult to accurately recycle supercritical CO_(2) dyeing wastewater,which affects the industrialization of the supercritical CO_(2)(SC-CO_(2))dyeing process.The supercritical CO_(2) dyeing waste of Reactive Blue M-2GE is analyzed by liquid chromatography-mass spectrometry,and the best mobile phase ratio is obtained.It is calculated that the available dyes in the supercritical CO_(2) dyeing waste accounted for 70.15%of the total dyes in the waste.According to this test data,the Reactive Blue M-2GE supercritical CO_(2) dyeing wastewater can be accurately reused,making it possible to industrialize the SC-CO_(2) dyeing.
