本文在空气—乙炔焰中,研究了SDS,CTAC和苯胺等对镍原子化行为的影响。SDS等试剂对镍吸收值均有显著的增感效应。当SDS或CTAC和苯胺共存时,其增感效应更大,且具有一定的加和性。有机试剂体系在增感的同时,亦提高了镍的选择性。所拟定的分析方法,用于MnV钢标样中镍的测定,结果满意。 In the air-acetylene flame, the effects of SDS, CTAC and aniline on the atomic behavior of nickel were studied. SDS and other reagents have significant sensitizing effects on nickel absorption. When SDS or CTAC and aniline coexist, their sensitization effect is greater, and has some additivity. Organic reagent system in sensation at the same time, also increased the nickel selectivity. The proposed analytical method was applied to the determination of nickel in MnV steel samples with satisfactory results.
