【摘要】 本文介绍了用石墨炉原子吸收法测定水中铊,也研究了各种基体和原子化器对测定水中铊的效果。实验表明,热解涂层平台以及含有10μg/L钯溶液分别是较好的原子化器和基体改进剂。方法的灵敏度是0.68μg/L,相对标准偏差为1.5～2.7%,回收率为95～103%。更多还原

【Abstract】 The determination of T1 in water by GFAAS has been described in this paper, and the effects of various matrix modifiers and atomizers to determine T1 are also being studied. Experiments show that the pyrolytic coated graphite platform is a better atomizer and the solution containing 10 μg/L Pd is also believed to be better matrix modifier. The sensitivity of this method is 0.68μg/L. The relative standard deviation is 1.5～2.7% and the recovery is 95～103%.更多还原
