摘要

摘要: 采用试验对比研究的方法测试武汉某玻璃窑烟气中氟和氯的浓度,结果表明:采用EPA Method 26A方法进行采样,一次采样可获得气态氟、气态氯、卤化氢和卤素浓度等多个数据,相对误差小,具备节省时间和人力的优势。分析烟气吸收液优化的色谱条件:设定EG40淋洗液自动发生器KOH浓度为30 mmol/L;淋洗液流速为1.2 mL/min;进样量为25 μL。该方法相对标准偏差小于3.0%,精密度高,样品加标平均回收率为96.7%~104.3%,准确度良好,完全满足烟气样品吸收液氟离子和氯离子浓度的检测要求。

Abstract: The concentrations of fluorine and chlorine in flue gas of a glass furnace in Wuhan were determined by using experimental comparative method. The result shows that the sampling error of EPA Method 26A is lower. Through one sampling it can obtain multiple parameter data such as gaseous fluorine, gaseous chlorine, hydrogen chloride, halogen, etc. with the advantages of saving time and human resources. The chromatographic conditions for analyzing flue gas absorption are optimized. The KOH concentration of EG40 eluent automatic generator is set at 30 mmol/L, with the eluent flow rate of 1.2 mL/min and the injection volume of 25 μL. The method could fully meet the testing requirements of F ^-, Cl ^- for flue gas absorbent for its high precision with the relative standard deviation RSD less than 3.0% and good accuracy with sample average recovery rate of 96.7%-104.3%.
