Abstract: The Akebia trifoliate peel sample was digested with microwave addition concentrated nitric acid-perchloric acid,and the contents of zinc,plumbum and chromium were measured by flame atomic absorption spectrophotometry  method.The results showed that the order of the three heavy metal contents was w（Zn）＞w（Pb）＞w（Cr） in Akebia trifoliate peels,and their contents were 9.084×10-3%,6.868×10-3% and 3.241×10-3%,respectively.Recovery ratio of addition standard sample and its relative standard deviation (RSD) were 100.24%,99.87%,101.01% and 1.23%,1.22%,1.91%,respectively.This method used for determination of contents of zinc,plumbum and chromium in Akebia trifoliate peel achieved high recovery rate and accuracy,and great precision and repeatability.Therefore,it has good application value.
