| 摘 要： | 建立了一种测定交警头发中痕量铅的新方法.研究了在Tween-80存在下,铅与非水溶性试剂meso-四（4-氯苯基）卟啉的显色反应条件,提出了一个高灵敏度测定铅的分光光度法.络合物的最大吸收波长为466nm,组成摩尔比为1∶1,铅含量在0-6μg/10mL范围内有较好的线性关系,表观摩尔吸光系数为1.74×105L·mol-1·cm-1,并将其应用于交警头发中痕量铅的测定.

| Abstract: | This article establishes a determination of traffic police in the hair of a new method of traces of lead. It describes a chromogenic reaction of Pb （ Ⅱ ） with T （4-CIP）P in the presence of Tween-80. A highly sensitive and selective method for the determination of Pb （ Ⅱ ） has been developed. The Sorer band of the complex lies at 466nm. Beer＇s law is obeyed for lead in the range of 0-6μg/10mL. The molar ratio of complex is 1 ： 1 ,apparent molar absorptivity is 1.74×105L·mol-1·cm^-1. Results of the Dezhou City traffic content of lead in hair is much higher than that of the normal human. |
