尿铅是诊断铅吸收或铅中毒的重要指标之一。尿铅的测定常用双硫腙比色法,原子吸收光谱法(火焰或无火焰),示波极谱法等但这些方法有的灵敏度低,干扰因素多,操作复杂费时;有的需使用大量有机溶剂或有毒有害物质;有的则因仪器昂贵而难于推广。近年来,文献报道了有关氢化物发生法的资料,这种方法与多种检测技术联用,具有灵敏度高,操作简便快速,干扰少等优点,非常适用于微量砷、硒、锑、碲、铅等的测定。本文系统地摸 Urine lead is one of the important indicators to diagnose lead absorption or lead poisoning. Determination of urinary lead commonly used dithizone colorimetry, atomic absorption spectrometry (flame or no flame), oscillopolarography, etc. However, some of these methods have low sensitivity, interference factors, complex operation time-consuming; some need to use a large number Organic solvents or poisonous and harmful substances; while others are difficult to popularize because of expensive instruments. In recent years, the literature on the hydride generation method reported in the literature, this method combined with a variety of detection techniques, with high sensitivity, easy operation, less interference and so on, is very suitable for trace arsenic, selenium, antimony, tellurium, Lead and other determination. This article systematically touch
