OBJECTIVE To establish a ICP-MS method to determine 6 elements of Cu,Cd,Cr,Pb,Sn and Ba in polypropylene infusion bottles.METHODS The content of 6 metallic elements in polypropylene infusion bottles was determined by ICP-MS.RESULTS The linear range was 0~0.3μg· mL-1 while the correlation coefficient in 0.9992~0.9999 and the detection limit was lower than 0.0004μg· mL-1 with recovery rate in 97.7%~100.8%and relative standard deviation( n=6) less than 2.0%.COCLUSION The proposed method is sensitive,accurate and fast with a low detection limit,it can be used determination of 6 metallic elements in polypropylene infusion bot-tles.
