For accurately analyzing trace elements in polypropylene raw materials for capacitor film,such two prepressing methods as dry ashing method and microwave digestion method are introduced for element determination of polypropylene raw materials for capacitor film.The effects of different methods on the anal-ysis results are compared.The characteristic of various analysis means are compared and the inductively coupled plasma mass spectrometry is chosen as the analysis method.Compared to the dry ashing method,the microwave digestion method has higher accuracy and precision.The microwave digestion method com-bined with ICP-MS method is suitable for determining trace metal elements in polypropylene raw materials for capacitor film.A method based on ICP-MS method has been set up for determining the content of trace metal elements in polypropylene raw material for capacitor film.
