本文介绍一个简单、快速、灵敏的荧光分光光度法测定生物材料、酒、合金中微量的锌。此法在pH4.6～4.9的水—乙醇(52%V/V乙醇)介质中锌与邻羟基苯醛硫代卡巴腙(SATCH)反应,迅速形成一种黄色络合物,在荧光分光光度计上激发波长为392nm,发射波长为467nm测定荧光的强度。此法的检出下限为10ng/ml,在15～100ppb锌时相对标准偏差为±1.65%,100～500ppb锌时为±1.70%, This article describes a simple, rapid and sensitive fluorescent spectrophotometric determination of trace amounts of zinc in biomaterials, wines, and alloys. In this method, zinc was reacted with o-hydroxybenzaldehyde thiocarbazone (SATCH) in water-ethanol (52% V / V ethanol) at pH4.6 ~ 4.9 to form a yellow complex rapidly. The intensity of the fluorescence was measured with an excitation wavelength of 392 nm and an emission wavelength of 467 nm. The detection limit of this method was 10 ng / ml, the relative standard deviation was ± 1.65% at 15 ~ 100 ppb zinc, ± 1.70% at 100 ~ 500 ppb zinc,
