原子吸收分光光度法连续测定矿石中铜、铅、锌、镉、铋、钴的资料已有报导,本方法在以上资料基础上,结合我所生产实际,在自装的仪器上做了工作条件选择,无机酸和混合无机酸的影响、杂质干扰及样品结果对照回收等方面实验,结果令人满意,本方法已用于生产。在5％盐酸介质中,以空气——乙炔火焰对六元素进行连测时,这六元素相互之间没有干扰,所做的31种杂质除钒和镁对铅及硅对锌有干扰外,余者均无干扰。我们采用在标准和试样溶液中同时加入一定量
The continuous determination of copper, lead, zinc, cadmium, bismuth and cobalt in ore by atomic absorption spectrophotometry has been reported. Based on the above data and the actual conditions of production, this method has been carried out on self-installed instruments Selection, the effect of inorganic acids and mixed inorganic acids, impurity interference and sample control and other aspects of the experimental recovery, the results are satisfactory, the method has been used in the production. In 5% hydrochloric acid medium, the air - acetylene flame connected to the six elements, the six elements have no interference with each other, made of 31 kinds of impurities in addition to vanadium and magnesium on the lead and silicon on zinc interference, No interference from the rest. We used in the standard and sample solution at the same time by adding a certain amount
