微量铅是纯金属及合金中的有害成份,因此,微量铅的测定是冶金和其他工业生产控制的重要项目。铅及其盐类是有毒的,且有积累性,为此,微量铅也是环境监测的主要控制成份之一。原子吸收光度法与方波、示波极谱法等虽能成功地用于微量铅的测定,但由于光度法具有一定灵敏度、简单、易于普及等特点,所以在实际工作中仍获得广泛应用与继续研究。
Trace lead is a harmful component of pure metals and alloys, therefore, the determination of trace amounts of lead is an important project in metallurgy and other industrial production control. Lead and its salts are toxic and accumulative, and trace amounts of lead are also one of the main control ingredients for environmental monitoring. Although atomic absorption spectrophotometry and square wave, oscillopolarographic and other methods can be successfully used for the determination of trace lead, but due to the characteristics of a certain sensitivity, simple, easy to popularize, it is still widely used in practical work Continue to study.
