水溶性卟啉衍生物与锌的显色反应已有很多报道,Ishii 等人曾经提出以 meso-四(N-甲基-3-吡啶基)卟啉[简称 T(3-MPy)P,1]分光光度测定锌的方法.我们研究了以1测定痕量锌的荧光光度法,其灵敏度较其它水溶性卟啉衍生物测定锌的分光光度法要高,检出量为1ppb,线性范围为0—1.0μg/25mL.本法比较简便,已用于测定自来水和头发中的微量锌,结果满意. The color reaction of water-soluble porphyrin derivatives with zinc has been reported a lot. Ishii et al. Proposed to use meso-tetrakis (N-methyl-3-pyridyl) porphyrin [ ] Spectrophotometric method for the determination of zinc.We studied the determination of trace zinc with a fluorescence spectrophotometry, the sensitivity of zinc-based than other water-soluble porphyrin derivatives measured spectrophotometry, the detection of 1ppb, the linear range of 0 -1.0μg / 25mL.This method is relatively simple, has been used to determine trace amounts of zinc in tap water and hair, with satisfactory results.
