【摘要】 本文研究了对硝基偶氮氯膦（CPA-PN）与Pd（Ⅱ）在H₂SO₄介质中的显色反应,建立了测定微量钯的直接和流动注射光度分析的新方法。该法简便,快速,选择性好,可不经分离直接测定二次阳极泥、氯化渣和铂钯精矿中的钯。更多还原

【Abstract】 In this paper, we have studied a color reaction of 2- ( 4-chloro-2-phosphonophenylazo ) -7- ( 4-nitro-phenylazo) -1, 8-dihydroxynaphthalene-3, 6-disulphonic acid and palladium in H2SO4, and developed the methods to determine microamount palladium by flow injection spcctrophotometry. The methods are rapid, sensitive and selective. These methods have been applied to determine palladium in anode mad and chloride residue without preliminary separation and satisfactory results were achieved.更多还原
