【Abstract】 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.更多还原
