摘要
通过对比测定矿山废水中铊含量的ICP-MS法与石墨炉原子吸收法,为选矿废水中铊的测定提供可靠的方法,在确定ICP-MS法与石墨炉原子吸收法工作曲线的基础上,对矿山选矿废水中铊进行测定并确定最佳测定方法,检测结果中石墨炉原子吸收法的测定结果 1.57μg/L,加标回收率为94%~108%;ICP-MS法的测定结果为1.92μg/L,加标回收率为86%~98%;结果表明,对于复杂水体中铊的测定,石墨炉原子吸收法具有较高的抗干扰能力、重现性、准确度和精密度,即矿山选矿废水中铊的含量检测石墨炉原子吸收法优于ICP-MS方法。
Comparing the determination of thallium content in mine wastewater by ICP-MS method and graphite furnace atomic absorption spectrometry,provide a reliable method for the determination of thallium in mineral processing wastewater,based on determining the ICP-MS method and graphite furnace atomic absorption spectrometry working curve,the determination of thallium in mining mineral processing wastewater and to determine the optimal method for the determination of the detection results in graphite furnace atomic absorption spectrometry determination results of 1. 57μg/L,the recovery rate is 94%-108%; the test results of the ICP-MS method is 1. 92 μg/L,the recovery rate is 86%-98%; as a result,the complex determination of thallium in water by graphite furnace atomic absorption method has high reproducibility of anti-interference ability,accuracy and precision,the content of graphite furnace atomic detection of thallium in mining mineral processing wastewater absorption method is better than the ICP-MS method.
