Abstract

A method for the treatment of ultra-light elements which cannot be accurately measured directly by X-ray fluorescence analysis has been established. Treating an ultra-light element as the elimination component in the de Jongh-Norrish equation during the calculation of theoretical α coefficients and then as balance component when analyzing the unknown element, it is possible to obtain reasonable results for ultra-light element components. Li~2O in lithium potassium niobate crystals and B~2O~3 in two types of glass were determined by this method. The results agree with those by ICP-AES and chemical titration respectively.
