原子吸收光度分析法,具有分析速度快、灵敏度高、共存元素干扰少或容易消除、仪器设备简单和操作简便等优点,故近年来在冶金、地质、农业、化工、生物、医疗卫生和环境保护等部门的分析工作中已广为采用。根据我所的具体情况,我们选择仪器结构简单、材料零件容易解决和电检测线路简单的单光束交流调制方式的方案,用Unicam S.P.500型分光光度计改装成一台原子吸收分光光度计,并应用于矿石中钙、镁、铁、锰、银、铋、锌、铜等元素的测定,效果较好。
Atomic absorption spectrophotometry, with the advantages of fast analysis speed, high sensitivity, less interference or coexistence of element interference, simple equipment and simple operation, so in recent years in metallurgy, geology, agriculture, chemical, biological, medical and environmental protection Analysis of other departments has been widely used. According to my specific situation, we choose the instrument structure is simple, easy to solve the material parts and electrical detection circuit simple single-beam AC modulation scheme, using Unicam SP500 spectrophotometer modified into an atomic absorption spectrophotometer and application Determination of calcium, magnesium, iron, manganese, silver, bismuth, zinc, copper and other elements in the ore, the effect is better.
