| Abstract: | The polyester samples were digested by wet and microwave methods, and the results of sample reproducibility tested by ICP - MS were obtained. Measured values of wet digestion sample was 2857.46 μg/g （ RSD was 1.08% ） , and that of microwave digestion sample was 2 599.21 μg/g （RSD was 2.76% ）. The detection limits of the two methods were obtained, the detection limit of wet digestion was 4.0 μg/g, and that of microwave digestion was 9.5 μg/g. The spiked recovery testing was carried out, the range of wet method was 84.82% -98.57% （ average value was 94.20% ） , and that of microwave method was 82.04% - 104.18% （ average value was 87.76% ）. By comparison, the wet digestion method is more beneficial to digest the polyester samples. |
