QUANTITATIVE ANALYTIC METHOD FOR ANTIMON OR CADMIUM

摘要

The present invention comprises the steps of preparing talc powder, which is a blank powder standard sample; Adding antimony or cadmium to talc powder to prepare a standard powder sample of two or more different concentrations; Selecting an interference element whose energy value is within the range of the detected energy value of antimony or cadmium from among the detected winsos by irradiating X-rays on the analysis sample; Deconvolution of correcting the detection energy peak of antimony or cadmium from the detected energy peak of the overlapping interference element among the energy peaks detected by irradiating X-rays to the powder standard sample for each concentration in the step of selecting the interference element ( deconvolution) step; Preparing a standard calibration curve by performing the deconvolution step after irradiating each of the prepared powder standard samples for each concentration with X-rays; And measuring the concentration of antimony or cadmium in the analysis sample according to a standard calibration method using a standard calibration curve prepared by irradiating X-rays on the analysis sample to detect the energy peak, and then measuring the detected energy peak value by a standard calibration curve. It relates to a method for quantitative analysis of cadmium.
