What is An approach to the solution of matrix problems in the XRF analysis of lead–zinc ore by the use of an internal standard and mathematical corrections about?
For the determination of the lead, zinc and iron contents of bore-hole samples from the Rampura-Agucha lead-zinc deposit, x-ray fluorescence spectrometry has been used. The concentration range of the metals, present in the ore body as galena, sphalerite, pyrite and pyrrohotite, is very wide: for Zn 0-30%, for Pb 0-10% and for Fe 1-16%. An internal standard method and a concentration-based correction equation have been used to solve the effect of matrix variations, which is the major problem in the development of the programme. Copper added as copper sulphate, which also acts as a good binder, was used as an internal standard for zinc. For Pb La, an adjacent Rayleigh diffraction line, Au LP,, was used as an internal standard and partially compensates for the matrix effect. The residual correction is made by the use of a mathematical model. For iron, only a mathematical correction is made. There is good agreement between the XRF and wet chemical analysis results for zinc and lead. For iron, the absolute differences are larger, but the correlation coefficient is good for average analysis of a series.
