摘 要:化纤厂棉浆粕废水在酸性条件下经乙醚萃取———Kuderna-Danish(K-D)浓缩器浓缩,采用气相色谱-质谱(GC/MS)联用仪对其有机污染物进行了分析研究。结果表明,在该废水中检测出14种有机物,主要污染物为有机酸类,占有机物总量的35.19%。其次为酯类和酮类,分别占有机物总量的30.03%和19.68%。此外,浆粕废水中还检测出二苯胺和环境优先污染物苯酚,分别占有机物总量的7.85%和5.42%。The organic pollutants in cotton pulp wastewater were extracted with dimethyl ether under acidic conditions and concentrated using a Kuderna-Danish concentrator. CrC-MS was used for the analysis of pollutants in the concentrate. 14 organic matters were identified, including the major compounds organic acids, esters and ketones with concentration of 35.19%, 30. 03% and 19. 68% respectively. In addition, diphenylamine and phenol as priority pollutant were also identified amounted to 7. 85% and 5.42% respectively, of the total organic pollutants.
