摘要	A rapid multi-clement analysis method for clay mineral samples was described. This method utilized a polarized wavelength dispersive X-ray fluorescence spectrometer-Axios PW4400,which had a maximum tube power of 4 000 watts. The method was developed for the determination of As, Mn, Co, Cu, Cr, Dy, Ga, Mo, P, Pb, Rb, S, Sr, Ni., Cs, Ta, Th, Ti, U, V, Y, Zn, Zr, MgO, K(2)O, Na(2)O, CaO, Fe(2)O(3), Al(2)O(3), SiO(2) and so on. Thirty elements in clay mineral species were measured by X-ray fluorescence spectrometry with pressed powder pellets. Spectral interferences, in particular the indirect interferences of each element, were studied. A method to distinguish the interference between each other periodic elements in element periodic table was put forward. The measuring conditions and existence were mainly investigated, and the selected background position as well as corrected spectral overlap for the trace elements were also discussed. It was found that the indirect spectral overlap line was the same important as direct spectral overlap line. Due to inducing the effect of indirect spectral overlap, some elements jlike Bi, Sn, W which do not need analysis were also added to the elements channel. The relative standard deviation (RSD) wits in the range of 0.01% to 5.45% except three elements Me, Cs and Ta. The detection limits, precisions and accuracies for most elements using this method can meet the requirements of sample analysis in clay mineral species.
