氧弹燃烧离子色谱法同时检测焚烧废弃物中氟、氯、溴、硫多元素含量

Simultaneous Determination of Fluorine,Chlorine,Bromine and Sulfur in Incineration Wastes by Oxygen Bomb Combustion Ion Chromatography

采用氧弹燃烧离子色谱法同时检测焚烧废弃物中氟、氯、溴、硫含量。进行了方法检出限测试、标准物质测试、实际样品测试、标准样品加标回收实验验证方法准确度和精密度研究。4种元素的方法检出限在1.4~13.8 mg/kg、方法加标回收率在91.4%~105.5%、测定值的相对标准偏差<4.5%。氧弹燃烧离子色谱法检测焚烧废弃物中氟、氯、溴、硫含量准确度高,方法可行。

The content of fluorine,chlorine,bromine and sulfur in incineration waste was determined by oxygen bomb combustion ion chromatograph.The accuracy and precision of the method were verified by detection limit test,standard material test,actual sample test and standard sample recovery experiment.The detection limits of the four elements were 1.4~13.8 mg/kg,the recoveries were 91.4%~105.5%,the relative standard deviation of the measured values was<4.5%.The determination of fluorine,chlorine,bromine and sulfur in incineration waste by oxygen bomb combustion ion chromatography is accurate and feasible.
