| 摘 要： | 合成了一种新的席夫碱荧光试剂--对羟基苯甲醛缩邻氨基苯甲酸(HBAA).研究了HBAA与汞离子的络合反应及其反应条件,HBAA在390.0 nm处有一强荧光峰,汞离子存在时,可与其形成稳定的络合物并使HBAA的荧光猝灭.利用该反应建立了荧光测定痕量汞的新方法,方法的线性范围为0 ～90.0 μg/L,检出限为0.61 μg/L.考察了40种常见共存离子的干扰影响,结果表明合成的HBAA试剂具有很高的选择性.该方法简便、快速,可用于矿泉水、自来水、河水中痕量汞的测定.

| Abstract: | A new fluorescent reagent 4-hydroxybenzaldehyde-anthranilic acid(HBAA) was synthesized.The coordination reaction of HBAA with Hg2+ was studied and the optimum reacting conditions were investigated.The result indicated that HBAA exhibited a maximum of fluorescence emission spectrum at 390.0 nm.The presence of Hg2+ would result in the fluorescence quenching of HBAA and the formation of Hg2+-HBAA complex.Based on this,a new spectrofluorimetric method for the determination of trace mercury using this reagent ha... |
