The invention relates to a method for measuring the rhodium content in rhodium-containing compound. The method comprises the steps of: 1) roasting by using high-temperature air to decompose rhodium-containing compound to be rough rhodium oxide; 2) grinding the rough rhodium oxide, immersing with 1-6mol/L hydrochloric acid for 1-5h at 50-70 DEG C and filtering to obtain filter residue; 3) reducing the filter residue with high-temperature nitrogen to change the rhodium oxide into rhodium powder; 4) weighing the rhodium powder and calculating rhodium content in the rhodium-containing compound. By adopting the method, rhodium content in the rhodium-containing compound with regular rhodium content which can be decomposed to be oxide by heating can be accurately measured, addition of other reagents for separation of rhodium is not needed, measuring error caused by repeated dilution with a power-spectral method is avoided, and rigorous requirements of high-temperature and strong-oxidizing-property wet digestion on the equipment are avoided. The method is convenient to operate without introducing solid impurities and has the advantages of high accuracy and recovery rate.
