基于Schiff碱的Th^(4+)荧光探针性能研究

Properties of Fluorescent Probe for Th^(4+) Based on Schiff Base

以N,N'-双-3-烯丙基水杨醛缩邻苯二胺(BASPDA)Schiff碱为荧光探针,研究了各种因素对BASPDA和Th(IV)配合物的荧光影响,建立了BASPDA荧光探针分析检测Th(IV)的方法,其线性范围为1.0×10-7mol/L^2.9×10-5mol/L,检出限为0.5×10-7mol/L.

The fluorescent probe based on Schiff base N, N＇-bis （3-allylsalicylidene）o- phenylened-ia-mine （BASPDA） for the detection of Th4 ＋ ion was described. It was studied that the various factors, such as solvents, pH, concentration, interfering ion, affected the flu- orescence of BASPDA and Th （IV） complex. And an approach was developed for the de- tection of Th4 ＋ based on BASPDA as fluorescent probe. The linear range was 1. 0 ×10^-7 mol/L -2.9×10^-5 mol/L,and the detection limit was 0. 5 ×10^-7 moL/L.
