title: [Determination of Pb, Cu and Sn in ancient bronze coins using X-ray fluorescence theoretical alpha coefficient method].
abstract: In this paper, the theoretical alpha coefficients of L-T equation were applied to the analysis of Pb, Cu and Sn in ancient bronze coins by X-ray fluorescence spectrometry. The results obtained in this way are in agreement with those by the fundamental parameter method and the simulant standard samples method, because this method and the simulant standard samples method were both developed from the fundamental parameter method, and the standard samples are the same. The calculation of element concentration is simple and rapid, but the precision of the results depends relatively largely on the concentration range of the standard samples by this method.
