| Abstract: | The method of measuring trace Pb in tipping paper by flow injection-Hydride generation-atomic absorption spectrometry was studied. The optimum experiment conditions for hydride generation were investigated.Recovery of the method was 95.0% ~104.5%,and detection limit was 0.22 ng/mL,linearity was kept in range of 0~50 ng/mL,the linear regression equation is y= 0.012x 0.0106,the correlation coefficient is 0.999 7,and the relative standard deviation(RSD) was 1.2% ~ 3.3 %. |
