摘要
碘量法测定固定污染源二氧化硫的方法误差较大、准确度较低。研究结果表明 :若采用烟气加热、吸收瓶放入冰水浴中的方法采样 ,定期对仪器进行检定和流量校准 ,在吸收液中加入稳定剂 ,就能保证采集到真正有代表性的样品 。
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.
