1.碘化(N,N-二甲基)氢化吡啶盐可以用作二价钯离子的定性分析试剂,灵敏度在点滴板上为0.2γ(1:200,000),在纸上为0.006γ(1:200.000)。 2.铂离子与试剂生成类似的棕色沉淀,但可以用加入大量的磷酸根除去其干扰。铋和汞(Ⅱ)离子与试剂生成红色沉淀,但可以用加入浓盐酸以消除之。Ag~+,Pb~(++),Cu~(++),Fe~(3+),Tl~(+),Sb~(3+)的干扰比例限度及灵敏度也测定过。 3.用点滴色层分析法,可以在包含二十五种阳离子(包括铋,汞(Ⅱ),铂(Ⅳ))的混合物中直接检出0.006γ(1:180,000)的钯(Ⅱ)离子,各离子对钯的浓度比例界限皆为1:50。
1. (N, N-dimethyl) hydrogenated pyridinium iodide can be used as a qualitative analytical reagent for divalent palladium ions with a sensitivity of 0.2γ (1: 200,000) on a drop plate and 0.006γ (1 : 200.000). 2. Platinum ions produce a brown precipitate similar to the reagent, but can be removed by adding large amounts of phosphate. Bismuth and mercury (II) ions and reagents generated a red precipitate, but can be used to add concentrated hydrochloric acid to eliminate it. The limits of the interference ratios and the sensitivities of Ag ~ +, Pb ~ (++), Cu ~ (++), Fe ~ (3 +), Tl ~ (+) and Sb ~ (3+) were also determined. 3. By drip chromatography, palladium (II) ions of 0.006γ (1: 180,000) can be directly detected in a mixture containing twenty-five cations (including bismuth, mercury (Ⅱ) and platinum (Ⅳ) , Each ion to palladium concentration ratio of the limit of 1:50.
