Abstract:

针对蚀刻废液及其回收后生产的碱式氯化铜产品中二噁英(PCDD/Fs)和二噁英类多氯联苯(dl-PCBs)进行了分析研究,并比较了采用去除工艺前后两类污染物含量水平的变化特征.利用高分辨气相色谱/高分辨质谱对样品中PCDD/Fs和dl-PCBs进行分析,结果表明,氯化铜废液中PCDD/Fs和dl-PCBs的平均总浓度分别为264、139pg·mL-1,而铜氨液中浓度分别为0.09、0.50pg·mL-1;碱式氯化铜产品中浓度分别为106pg·g-1(2.79pgWHO-TEQ2005·g-1)和27.8pg·g-1(0.69pgWHO-TEQ2005·g-1);而经过吸附和过滤等去除工艺后,产品中PCDD/Fs和dl-PCBs的TEQ浓度水平分别降低至0.10—0.25pgWHO-TEQ2005·g-1和0.05—0.72pgWHO-TEQ2005·g-1,满足欧盟对于矿物源性饲料添加剂中PCDD/Fs和dl-PCBs的限量标准要求.研究表明该工艺能够有效去除利用蚀刻废液生产碱式氯化铜过程中的二噁英类污染物.
