| Abstract: | It is reported the lithium metaborate fusion method decompose technique is used in the X - ray fluorescence spectrometry method for determination of major and minor elements of catalytic stocks from Kaolin clay. The results provided by this method are in agreement with certified values and with those provided by classical chemical methods. The precision of the method is RSD 〈 0. 83% for major and minor components. The method is simple, rapid, accurate and precise. The time consumed per sample is only 1/8 of that by classical chemical methods. It is used in the determination of Kaolin clay with the result is satisfactory. |
