【摘要】 在6×10^-4M α-呋喃甲酰二肟-0.4M NH₄OH-NH₄Cl底液中,Pd²⁺有一灵敏的微分脉冲极谱波,峰电位为-0.75V（对Ag/AgCl电极）,峰电流与0.01～0.50μg/ml浓度范围的钯呈线性关系。研究了极谱波的性质和机理,认为该波系络合吸附波。本方法应用于活性碳钯催化剂样品的测定,结果令人满意。更多还原

【Abstract】 In a supporting electrolyte of 6×10^-4M a-furildioxime-0. 4M NH₄OH-NH₄Cl, a sensitive differential pulse polarographic catalytic wave of Pd（Ⅰ）has been observed. The peak potential of the wave is at -0. 75V（vs, Ag/AgCl）. The peak current is linearly proportional to the concentration of Pd ion in the range of 0. 01 to 0. 5μg/ml. It is deduced that the wave is the adsorptive-complex one. The method has been applied to analyze samples of the charcoal containing Pd catalyst with satisfactory results.更多还原
