摘要
建立测定肼类推进剂汞、砷的氢化物发生、原子吸收法,并考察了盐酸、硼氢化钠浓度对测定结果的影响,本方法精密度小于3%,回收率范围为90.1%~111.9%,检测汞、砷的检出限分别为0.88μg/L、1.06μg/L。
A method for determining As and Hg by hydride-generation atomic absorption spectrometry was established. The effects of Hydrochloric acid and Sodium borohydride' concentration were studied. The detection limits of Hg and As were 0.88ug -L-1 and 1.06ug-L. The relative standard deviations of the method were below 3%and the recovery of standard addition were among90.1%-111.9%0
