将尿样用0.5%的四甲基氢氧化铵溶液稀释后直接进样,采用电感耦合等离子体质谱法进行尿中溴离子检测。在选定的范围内具有良好的线性关系,相关系数大于0.999,方法检出限为16.9μg/L,相对标准偏差为0.83%~1.85%。该法简便、快速、准确并且灵敏度高,可用于尿中溴离子的定量检测,可为1-溴丙烷职业接触人员的生物标志物监测提供支持。
Urine samples were diluted with 0.5% tetramethylammonium hydroxide solution and directly injected into the urine to detect bromide in urine by inductively coupled plasma mass spectrometry. In the selected range, there is a good linear relationship, the correlation coefficient is greater than 0.999, the detection limit of the method is 16.9μg / L, the relative standard deviation is 0.83% ~ 1.85%. The method is simple, rapid, accurate and sensitive and can be used for the quantitative detection of bromide in urine. It can support the biomarker monitoring of 1-bromopropane occupational exposure workers.
