| Abstract: | The iodine value method, that is used to measure SO 2 content in fixed pollution sources, shows larger error and lower accuracy. The results of study demonstrate that sampling with the method of heating exhaust gas and putting absorption bottom into ice-water bath, making regular examination for instruments and correction of flow, and adding stabilizer into absorption liquid can guarantee that the collected samples possess real representativeness and obtain accurate and reliable results. |

| Keywords: | waste gas in fixed source monitoring of SO 2 iodine value method absorption efficiency accuracy |
