原子吸收法测定循环醋酸中钴锰含量

Determination of Co and Mn content in recycling acetic acid with atomic absorption spectrophotometry

介绍了原子吸收法测定PTA生产过程的循环醋酸中钴锰含量的方法 ,并把用该法测定的结果与X 射线荧光法测定结果进行比较 ,结果表明 ,前者精密度好 ,准确性高 ,速度快 ,杂质干扰小 。

Content of Co and Mn in recycling acetic acid in PTA production is determined by atomic absorption spectrophotometry.The results is compared with those obtained from X ray fluorescence.The results show that atomic absorption spectrophotometry is precise,exactly quickly and no interfrence,it can replace X ray fluorescence exactly.
