一种定性分析ABS生产废水中溶解性有机物的方法

The Qualitative Analysis Method of the Dissolved Organic Matter(DOM) for ABS Wastewater

联合使用气质联用色谱(GC-MS)、傅里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-氰基乙醚、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GC-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.
