矿石及有色金属中的微量锌,目前多采用氰化物掩蔽干扰元素,双硫腙萃取分光光度法测定。该法虽然准确、可靠,但操作手续繁琐,同时需使用剧毒的氰化物。其它分光光度法也往往存在着试剂空白和元素间干扰等不利因素。原子吸收分光光度法测定锌,早在1958年已有报导。由于方法具有灵敏度高、元素干扰少、操作简易、快速和准确等优点,因此近年来,得到了广泛的应用。但是,用原子吸收分光光度法测定矿石及金属镍、钴中微量锌的详细报导却较
Ore and non-ferrous metals in the small amount of zinc, the current use of cyanide masking interference elements, dithizone extraction spectrophotometric determination. Although the law is accurate and reliable, but the operating procedures cumbersome, while the use of highly toxic cyanide. Other spectrophotometric methods often contain unfavorable factors such as reagent blank and elemental interference. Determination of zinc by atomic absorption spectrophotometry, as early as 1958 has been reported. Because of its advantages of high sensitivity, less element interference, simple operation, fast and accurate, the method has been widely used in recent years. However, the atomic absorption spectrophotometric determination of ores and nickel, cobalt, a small amount of zinc is reported in detail
