The invention discloses a method for measuring barium and calcium in industrial strontium carbonate by adopting gel X-ray fluorescence spectroscopy. The method comprises the steps of preparation of aseries of standard solutions, preparation of a solution to be measured, preparation of a gel sample, preparation of a standard curve and measurement of a sample to be measured. According to the method, the gel method is adopted for preparing the sample, so that the granularity effect of a tablet compression method is overcome and the standard sample is stable and easy to store; and the activity ofcalcium and barium ions in the solution to be measured can be enhanced without introducing metal cations by adding a certain amount of ammonium chloride, so that preparation of the gel sample is facilitated and the detection accuracy of calcium and barium measurement can be improved.
