摘　　要：利用电感耦合等离子-质谱(ICP-MS)、离子色谱(IC)、气-质联用(GC-MS)、三维荧光光谱(3D-EEMS)等仪器联用分析手段,分别从涉污企业外排污废水水样中测取具有广泛代表性的无机元素及金属离子、阴离子、有机小分子与有机大分子等信息,从中选出对于污染源溯源有价值的化学指纹。对多种模拟水样进行污染源溯源的实验结果表明,借助上述仪器联用分析技术得到的污废水化学指纹具有一定的普适性及良好的稳定性和可加和线性,其高灵敏度足以满足超排指纹检出的要求;通过超排指纹与涉企指纹比对排查能够顺利锁定污染源,实现对超排者的溯源追责。Four analytical techniques(gas chromatography- mass spectrometry(GC- MS),ion chromatography(IC),inductively coupled plasma mass spectrometry(ICP-MS) and three-dimensional excitation-emission matrix spectroscopy(3D-EEMS)) were employed to analyze river and wastewater samples in order to collect information to build a wastewater chemical fingerprint database. By matching the analytical data for synthetic wastewater samples from multiple suspect sources within the database,it was found that the chemical fingerprints are stable and applicable. As a result,the source responsible for illegal pollution can readily identified.
