摘要：

合成了四(4-羟基-3-乙氧基苯基)卟啉, 用元素分析、质谱、紫外-可见光谱、红外光谱及核磁共振氢谱进行了表征, 研究了该卟啉与铅离子的显色反应条件. 结果表明, 当pH=11.0时, 在十二烷基磺酸钠存在下, 沸水浴加热5 min反应完全, 在473 nm处测得配合物的表观摩尔吸光系数为2.08×105 L/(mol·cm), 铅量在0~12 μg/25 mL范围内符合比尔定律, 用此法成功地测定人发标准物质中的微量元素铅的含量.

Abstract:

A new color reagent, tetra(4-hydroxy-3-ethoxyphenal) porphyrin, was synthesized and characterized by elemental analyses, MS, UV-Vis spectrum, Infrared spectrum, and 1H NMR spectrum. In a pH=11 solution with NaOH and Na[B4O5(OH)4]·8H2O, the complex of this color reagent with Pb was formed. The apparent molar absorptance of the complex was 2.08×105 L/(mol·cm)(λ=473 nm ). Beer′s low was obeyed for Pb in the range of 0—12 μg/25 mL. The reagent was applied to the determination of Pb in the certified reference material(GBW07601) successfully.

Key words: Tetra-(4-hydroxy-3-ethoxyphenyl) porphyrin, Pb, Complex, Color reagent
