Observation of x-ray interferences on apatite and secondary phosphate minerals in Sukulu phosphatic soil, Uganda

The x-ray fluorescence spectrometric analysis for P2O5 in phosphate minerals has been carried out. Correction of algorithms proposed by Lucas-tooth-Pyne, Rasberry-Heinrich and de-Jongh have been applied. The combination of double briquetting technique, coefficient method of corrections and solution of linear equation yields a rapid and accurate method. It has been observed that the results have been significantly improved after applying. Lucas-tooth-Pyne model for correction. Experimental conditions have been computed.
