Method for measuring total chlorine content and total sulfur content in nuclear-grade ion exchange resin

The invention discloses a method for measuring the content of total chlorine and total sulfur in nuclear-grade ion exchange resin. The method comprises the following steps: cleaning a resin sample, and drying to constant weight; carrying out pre-oxidation on the constant-weight resin sample at 450-550 DEG C, and continuously introducing oxygen in the pre-oxidation process; gas generated in the pre-oxidation process is pushed into absorption liquid for gas adsorption; after pre-oxidation is finished, the resin sample is subjected to cracking combustion at the temperature of 1000-1200 DEG C, and oxygen is continuously introduced in the cracking combustion process; gas generated in the cracking combustion process is pushed into absorption liquid for gas adsorption; after the cracking combustion is finished, placing the resin sample at 1000-1200 DEG C for oxygen-enriched combustion, and continuously introducing oxygen in the oxygen-enriched process; gas generated in the oxygen-enriched combustion process is pushe
