矿石中镉的测定,以极谱法较为普遍;而原子吸收分光光度法,则有操作简便,灵敏度较高和选择性较好的优点。但在目前,比色法和分光光度法,仍是测定矿石中镉的必要方法。用双硫腙萃取光度法测定镉已有三十多年的历
Ore determination of cadmium, the polarographic method is more common; and atomic absorption spectrophotometry, there are simple, high sensitivity and selectivity of the advantages. However, at present, colorimetric and spectrophotometric methods are still the necessary methods for the determination of cadmium in ores. Dithizone extraction spectrophotometric determination of cadmium has been more than thirty years calendar
