本文研究了在氨性介质中，痕量铜（Ⅱ）催化过氧化氢氧化煌焦油兰褪色反应及其动力条件，建立了一种催化光度法测痕量铜（Ⅱ）的新方法，线性范围为002－10μg／25ml，检出限为39×10－10g／ml．用于环境水标样，铝合金标样中痕量铜（Ⅱ）的测定，结果满意．
In this paper, a new catalytic spectrophotometric method for the determination of trace copper (Ⅱ) was developed by using trace copper (Ⅱ) as a catalyst to catalyze the oxidative decoloration of oxidative hydroquinone hydroperoxide and its kinetic conditions in ammonia media. The linear range 002-10μg / 25ml, the detection limit of 39 × 10-10g / ml. Used for the determination of trace copper (Ⅱ) in environmental water standard and aluminum alloy standard samples with satisfactory results.
