示波极谱测定微量铅已是成熟的方法,在生产中早已广泛应用,但应用于金属钻镍的测定中,由于大量钻、镍及铬的干扰,不能成功地进行检测。近年来,巯基棉富集分离微量元素,已广泛应用于各种方法中,而利用巯基棉分离富集金属钻镍及其盐类中微量铅,示波极谱测定未见报导。本文应用巯基棉富集微量铅与硫酸镍及 The determination of trace lead by oscillopolarography is a mature method and has been widely used in the production. However, the determination of nickel in metal drilling can not be successfully detected due to the interference of a large amount of cobalt, nickel and chromium. In recent years, sulfhydryl cotton enrichment and separation of trace elements has been widely used in various methods, and the use of thiol cotton separation and enrichment of trace metals in nickel and its salts, oscillopolarographic determination has not been reported. In this paper, the use of thiol cotton enrichment of trace lead and nickel sulfate and nickel
