The invention discloses a method for determining the content of
zinc in the
zinc concentrate through energy-dispersive X-
ray fluorescence spectrometry. The method comprises the following steps: 1, preparing a plurality of
zinc-iron working liquids, converting the
mass concentrations of Zn in the operating liquids to Zn
mass percentage concentrations, detecting the Zn
mass percentage concentrations with an energy-dispersive X-
ray fluorescence spectrometer as a
detector, recording the
fluorescence intensity during each time injection of a sample, and making a working curve; and 2,
processing the zinc concentrate as a sample to prepare a sample solution, injecting the sample solution under detection conditions for making the working curve, recording the
fluorescence intensity displayed on the
detector, reading out the Zn mass percentage concentration corresponded to the
fluorescence intensity according to the determined working curve, and calculating according to a specific formula to obtain the mass percentage concentration of simple substance zinc in the sample. The method utilizes a solution process to eliminate or basically eliminate the matrix effect, so the zinc content can be accurately determined; and the method has the advantages of simple operation, short detection period, good detection result accuracy and high precision.
