本文报道了Ｔｂ－吡哌酸生成络合物后，在紫外光照射下发生分子内能量传递使Ｔｂ产生特征荧光，其荧光强度与吡哌酸的浓度成线性关系，由此建立了一种灵敏、快速的分析吡哌酸的方法。此方法具有背景干扰小，选择性高和体系中铽的荧光寿命长等特点。尤其适用于血清、尿样等体液分析，回收率在９４．６％～１０２％。该方法检出限为３．６ｎｇ／ｍＬ。其线性范围是５．０×１０－８～４．０×１０－６ｍｏｌ／Ｌ。
In this paper, Tb-pipemidic acid complex formation was reported. Under the irradiation of ultraviolet light, intramolecular energy transfer resulted in the characteristic fluorescence of Tb, and its fluorescence intensity was linear with the concentration of pipemidic acid. Thus, a sensitive , Rapid analysis of pipemidic acid method. This method has the characteristics of small background interference, high selectivity and long fluorescence lifetime of terbium in the system. Especially for serum, urine samples and other body fluid analysis, the recovery rate of 94.6% ~ 102%. The detection limit of this method is 3.6ng / mL. The linear range is 5.0 × 10-8 ~ 4.0 × 10-6mol / L.
