本文提出了在三氯化铁存在下，以硫酸一重铬酸钾溶液溶解并氧化氧化铜粉中的低价铜为铜（Ⅱ），过量的重铬酸钾用硫酸亚铁溶液滴定以确定［２Ｃｎ（０）＋Ｃｎ（Ⅰ）］之含量。在硫酸－抗坏血酸－乙醛溶液中，浸出铜的氧化物，然后测定残渣中金属铜。在测出总铜量后，计算出氧化亚铜和氧化铜的含量。本法用于空气雾化－二次氧化生产氧化铜粉的工艺控制和成品分析，简便快速，结果准确。
In this paper, it is proposed that copper (II) should be dissolved and oxidized in the presence of ferric chloride by sulfuric acid-potassium dichromate solution, and excess potassium dichromate is titrated with ferrous sulfate solution to determine [ 2Cn (0) + Cn (I)]. In a sulfuric acid-ascorbic acid-acetaldehyde solution, copper oxide was leached, and the metal copper in the residue was measured. After measuring the total amount of copper, calculated cuprous oxide and copper oxide content. This method is used for air atomization - the process control and finished product analysis of the secondary oxidation of copper oxide powder production, simple and quick, the result is accurate.
