title: [Determination of Cu, Pb, Sn, Fe and Zn in the ancient Chinese bronzes by X-ray fluorescence filter paper method].
abstract: The determination of Cu, Pb, Sn, Fe and Zn in the ancient chinese bronzes has been performed using X-ray fluorescence filter paper method. The result is satisfactory. The samples are dissolved in the HCl-H2O2 system, ard then the solution is dropped on the filter paper. It is convenient for detection by XRF. In addition this method is efficient to reduce the matrix effect of sample. The correlative coefficients of calibration curves between element concentration and X-ray intensity are over 0.99. The rate of recovery is 97-104%, and the relative standard deviation for each element is less than 2.00%. The copper's result measured by this method agrees well with that of chemical method. This method is simple, rapid and accurate. It is also applied to determine the elements in the other ancient objects.
