| Abstract: | A method for simultaneous determination of four metal elements in metallic coating of waste plastics by ICP-AES was studied. The results show that: the correlation coefficients are over 0.999, the detection limits are 0.003～0.030 μg/ml, the average recoveries of standard addition are in the range of 94.8%～104.5%, with the relative standard deviations ranged from 1.0% to 4.7%. The testing method shows simple operation, good accuracy and high precision. It can meet the test requirements of metal elements in metallic coating of waste plastics. . |
