Abstract
Mathematical treatment for correcting the effect in quantitative X-ray spectrochemical analysis is carried out to study the relationship between the X-ray fluorescent patterns and composition of element of (Bi1-xSbx)2(Te1-ySey)3 system. The samples, which are prepared as standard, consist of four elements in the following concentration in weight percent; bismuth (063.46), antimony (050.33), tellurium (061.47) and selenium (049.67).
The parameter for absorption-excitation effects can be expressed in terms of empirical parameters relating to the pairs of elements used. The standard deviations (errors) and coefficients of variance in simultaneous equation method are respectively, as the followings; that is in α-line values: ±1.15% and ±4.3%, and in β-line values: ±0.9% and ±3.7%.
