【摘要】 在加压条件的氰化钠溶液中,对钯在不同氰化钠浓度、不同温度和不同氧压下进行了研究。研究结果表明钯的溶解随着温度的升高、氰化钠浓度的增加和氧压的增大而增大,在一定的时间钯氰化的溶解与钯氰配合物的分解速度达到一个平衡,在1.5Mpa、120℃时,30min 钯就能有效的溶解。更多还原

【Abstract】 In this paper,the dissolution of Palladium was measured in pressure clear cyanide solution.The data at different cyanide concentrations,different temperature and different Oxygen pressure are obtained. The dissolution of Palladium were increaseing with increasing cyanide concentration ,with increasing temperature and oxygen pressuer.A equivalence was reached during time which the dissolution of Pallatinum by pressure-oxygen-cyanide and decomposition of Pd（CN）₄^2-.The dissolution of Palladium reached maximum in pressure clear cyanide solution at 1.5Mpa,120℃,cyanide concentrations 2.5 mol m^-3and about 30min.更多还原
