| Abstract: | A mathematic model for the ICP-AES determination of cadmium in plastic was established.The calculation formula was deduced.Some data were collected in the procedure of analyzing the plastic sample and the various variable's uncertainties were calculated.The combined uncertainty and expanded uncertainty were finally obtained by synthesizing the uncertainties of various component variables. |
