邻羟墓萘醛水杨酰腙-铝高灵敏荧光反应及其应用

Fluorescent Reaction of 2-Hydroxy-1-naphthaldehyde Salicyloylhydrazone With Aluminium and Its Application

合成了新荧光试剂邻羟基萘醛水杨酰腙，研究了β－环糊精对试剂与铝形成包络物的适宜反应条件及Ｔｒｉｔｏｎ Ｘ－１００协同增敏作用。确定了形成包络物的包结比为１：１，包结常数为１．３７×１０＾３，测定铝的线性范围为０￣８０μｇ／Ｌ，检测限０．２４μｇ／Ｌ，是目前荧光法测定铝最灵敏的方法之一。应用于样品测定，结果满意。

The fluorescent reaction of 2-Hydroxy-1-naphthaldehyde salicyloylhydrazone(2-HNASH) withaluminum in the presence of β-cyclodextrin (B-CD) and the synergistic sensitizing effect of TritonX-100were studied. The inclusion ratio of β-CD to complex was 1 : 1 and its inclusion stability constant was1.37×103. The linear range of the proposed method was from 0.0 to 80 μg/L and the detection limit was0.24μg/L of aluminium. The sensitive method has been successfully applied to the determination ofaluminium in glucose injection and mussel.
