Abstract：According to GB 21550-2008 Restriction of hazardous materials in polyvinyl chlo-ride artificial leather,the content of dissoluble Cadmium in polyvinyl chloride artificial leather was determined by absorption spectrometry,and the sources of uncertainty in the measurement process was analyzed.The results showed that the uncertainty mainly derived from the standard material and the standard curve.Accordingly,normative operation should effectively improve the accuracy of measuring result.
