本文较详细研究了乳酸氟哌酸—锆（Ⅳ）—四溴二氯萤光素三元络合物。在可见光谱区，创立了一种简便、快速、测定痕量乳酸氟哌酸的新方法。络合物的最大吸收峰在５５６ｎｍ处。表观摩尔吸光系数ε＝２．５８×１０４Ｌ·ｍｏｌ－１·ｃｍ－１。乳酸氟哌酸含量在０～７０μｇ／１０ｍｌ范围内遵守比尔定律。方法用于兽药中乳酸氟哌酸的测定，结果令人满意。
In this paper, a more detailed study of norfloxacin lactate - zirconium (IV) - tetrabromofluorescein dichloride fluorescent ternary complex. In the visible spectral region, a new method was developed for the simple and rapid determination of trace amounts of norfloxacin lactate. The maximum absorption peak of the complex is at 556 nm. The apparent molar absorptivity ε = 2.58 × 104L · mol-1 · cm-1. Beer’s law of norfloxacin content in the range of 0 ~ 70μg / 10ml obey Bill’s law. The method was applied to the determination of norfloxacin lactate in veterinary medicine with satisfactory results.
