摘要
以紫外分光光度法，采用水、ｐＨ５．８、ｐＨ６．８、ｐＨ７．２磷酸盐缓冲液为溶剂，对氟哌酸胶囊在不同ｐＨ值基质中的最大吸收波长变化进行观察比较，而后选择ｐＨ７．２磷酸盐缓冲液为溶剂，测定波长为３３０ｎｍ，吸收系数（Ｅ１％１ｃｍ）为３９０的最佳测定条件。
Ultraviolet spectrophotometry (solvents are water and defferent PH phosphatic buffer solutions) was used to determine the change of the wavelengths of maxium absorption of norflox-acin-capsule in defferent PH bases. The results show: the best determinative condition,solvent is phosphotic buffer solution which PH is 7. 2 and in this condition it's wavelengths is 330nm, absorptivity is 390.
