| Abstract: | Microwave digestion technique was used in decomposition of plastics samples and the contents of Cd,Pb,Hg and Cr was determined of by ICP-AES.The method of plastics microwave digestion was developed by validating the microwave digestion procedure and digestion reagent.Different element level and type plastics were determined.The RSD is between 1.8% and 2.4%, and the recovery of the method is between 97.3% and 98.8%.The method is proven to be accurate by determining the certificated reference Material and international proficiency test samples. This method can be used in Cd, Pb, Hg and Cr determination of different kinds of plastics. |
