Abstract
In this paper,ED-XRF (Energy-dispersive X-ray fluorescence spectrometry) spectrometric method for the determination of Pb,Cr,Cd,Hg in paints has been established . The experimental results showed a good linear relationship in the concentration range from25 mg/kg to 200 mg/kg . The detection limits were 13,7,4 mg/kg and 9 mg/kg for Pb,Cr,Cd and Hg,respectively. The recovery rates and the relative standard deviation of the method were in the range of 91. 8% - 101. 6% and 1. 2% -4. 3% .respectively. As compared with national standard methods for the determination of Pb,Cr,Cd,Hg in paints,this method is simpler,faster and satisfied the semi-quantitative determination of Pb,Cr,Cd,Hg in paints with good accuracy and detection limits,can be applied to the heavy metals inspection in paints.关键词
