一种定性分析ABS生产废水中溶解性有机物的方法

摘要

联合使用气质联用色谱(GC-MS)、傅咀叶变换红外分光光度计(FTIR)及三维荧光光谱(EEM)等三种分析检测仪器对ABS树脂生产废水中的溶解性有机污染物进行全面的定性分析.检测结果表明气质联用色谱能够定性分析出该废水中苯乙酮、苯乙烯、二苯异丙醇、2-氰幕乙醚、双(2-氰基乙基)胺、3,3-硫代丙二腈、3-(二甲氨基)-丙腈、丙烯腈等21种溶解性有机物污染物,而FTIR和EEM的检测结果进一步的验证了GC2-MS检测结果的准确性和完整性.本研究结果为后续废水处理工艺的开发提供了重要的指导作用.%The dissolved organic matter (DOM) of acrylonitrile-butadiene-styrene (ABS) resin wastewater was qualitatively analysed by gas chromatography with mass spectrometry(GC-MS), Fourier transform infrared spectrometer(FTIR) and three-dimensional excitation - emission matrix (EEM) fluorescence spectroscopy. The detected results shows that the GC-MS qualitatively analysed 21 dissolved organic pollutants, such as acetophenone, styrene, alpha, alpha-dimethyl-benzenemethanol, 3,3'oxybis-propanenitrile, 3, 3'-iminobis-propanenitrile, 3, 3'-thiobis-propanenitrile, 3-( dimethylamino)-propanenitrile and 2-propenenitrile. The results of Fourier transform infrared spectrometer (FTIR) and three-dimensional excitation-emission matrix (EEM) fluorescence spectroscopy could examine and certify the accuracy and integrity for the qualitative analysis of GC-MS.The results of this study provides an important guiding role for the development of wastewater treatment process.
