摘要
建立用紫外分光光度计同时测定精对苯二甲酸生产污水中三种主要芳香酸含量的方法,并讨论实际污水中所含有机物对测定结果的干扰。结果表明:本方法同时测定三种芳香酸含量时具有简便、快速及准确度较高等特点,适合实际生产过程使用。
UV spectrophotometer is used to simulta- neously determine the content of three main aroma- tic acids in the wastewater of PTA production,and the influence of the organics in wastewater on the determination results is discussed.The results show that this method is simple,quick and accurate in simultaneously determining the content of three aro- matic acids and is suitable for application in actual production.
