Experimental Studies in EDXRF on a New Linear Relationship for Fluorescence

Abstract

An experiment was carried out to verify a previously described linear relationship between ln(fluorescent intensity ratio of analyte to pure analyte/concentration of analyte) and ln(fluorescent energy) or, mathematically, ln( Ii/ciIi0 = a ln( Ei) + b. The best fit to our experimental data for elements from manganese to molybdenum for porcelain matrix is given by ln( Ii/ciIi0) = 2.401 ln( Ei) – 8.701 with a value of the gradient in agreement with the theoretical prediction.
