【摘要】 在NH₃·H₂O—NH₄Cl介质中,痕量Cu²⁺能强烈催化H₂O₂氧化溴甲酚紫褪色。据此建立了催化分光光度法测定痕量Cu²⁺的新方法,其灵敏度为1.1×10^-11g/ml,测定范围为0～12.0μg/L,该方法可直接用于动物血清中痕量铜的测定,分析结果良好。更多还原

【Abstract】 Cu（Ⅱ） in NH₃·H₂O—NH₄Cl medium can catalyze the decolorizing reaction resulting from the oxidation of Bromocresol Purple by hydrogen peroxide. A new Catalytic kinetic spectrophotometric method of detcrming trace Cu（Ⅱ） was obtained. The sensitivity of the method is 1.1×10^-11g/ml, the linear respondence is in the range of 0～12μg/L, The proposed method has been applied to determine Cu （Ⅱ）in animal serum samples with satisfactory result.更多还原
