氮肥厂铜洗液总铜含量分析是借助于空气中的氧使铜液中的一价铜全部氧化成二价铜,然后按测二价铜的步骤进行测定的。因此,测定总铜和一价铜含量的准确与否,决定于铜液中的一价铜是否全部被空气中的氧氧化成二价铜。按规定:铜液“在经常摇动下,自然氧化二小时……”来达到。小氮肥厂铜洗岗位分析工测定铜液总铜和一价铜含量时,都是采用人工手摇锥瓶里的铜
The total copper content of the copper washing liquid in the nitrogenous fertilizer plant is determined by the step of measuring the copper divalent by oxidizing all the copper in the copper by means of the oxygen in the air. Therefore, the determination of total copper and monovalent copper content is accurate or not, depending on whether the monovalent copper in the copper liquid is all the oxygen in the air oxidation into divalent copper. According to regulations: copper liquid “under constant shaking, natural oxidation two hours ... ...” to achieve. Small nitrogen fertilizer plant copper wash job analysis workers to determine the total copper and copper content of copper, are manual manual cone in the copper
