Abstract: Flame atomic absorption spectrophotometry is utilized to investigate the effects of acid,lead and other impurities on the determination of copper.It is found for the first time that the interference of methylsulfonic acid and lead in the system can be simultaneously eliminated by employing hydrogen peroxide catalysis and heating pretreatment.The results show that the detection limit of copper is 0.01 mg·L-1,the recovery of copper is 97.4%-101.7%,and the relative standard deviation (RSD,n=7) is less than 1.5%.
