摘要
本文首次提出将探针原子化技术和固体悬浮液进样技术相结合,使用自制的自动探针系统,对地质样品中铋、镉和铜的分析特性进行了详细的研究,同时与标准溶液的测定数据进行对比,采用本法测定标准样品的结果令人满意。
In this paper a new technique that combines slurry sampling with probe atomization in GFAAS is presented, in which a self-made automatic probe system is employed. Analytical characteristics of Bi,Cd and Cu in solid geological samples are investigated and compared with those of aqueous standard solution. The relative standard deviation of the method is in the range of 2.4～5.0% and the detection limits are 2.0×10.(-11)g for Bi,3.1×10^(-12)g for Cd and 6.8×10^(-11)g for Cu respectively. The recoveries of standard additions are from 94 to 108%. Results of the determination of reference samples are satisfactory.
