目前测定钢铁或铁矿石中的铜,普遍采用双环己酮草酰双腙(BCO)比色法,含量较低的采用铜试剂萃取办法,但我们认为以上操作较烦琐,特别是经常用有机试剂会影响操作人员的身体健康。钼铁中的铜是生产中必测有害元素,为满足生产需要,利用原子吸收法可以避免上述缺点,并且步骤简化,干扰少因而无需分离等优点,经过一段时间试验,情况良 At present, the determination of copper in iron and steel or iron ore is generally carried out by using the method of the colorimetry of Bocopheryl oxalate (BCO) and the method of extracting copper by a lower reagent. However, we think the above operation is cumbersome, Reagents can affect the operator’s health. Ferromolybdenum in the production of copper in the production of necessary harmful elements, in order to meet the production needs, the use of atomic absorption method can avoid the above shortcomings, and the steps are simplified, less interference and so without the advantages of separation, after a period of testing, the situation is good
