| Abstract: | The contents of lead,cadmium,arsenic,zinc and copper in the package were determined by ICP-OES.The instrumental detection limit of the five elements were 0.2—1.0 mg/kg,the relative standard deviation RSDs were 0.20%—1.4%,and the standard recovery range was 82.0%—94.7%.Lead,zinc and copper have been detected in the 10 batches of samples.The method is fast,accurate with low detection limits.It is suitable for determination of 5 heavy metal ions in express packages. |
