利用ＳｒＣｌ２和Ｐｂ（Ａｃ）２作为选择性重原子微扰剂，分别诱导出吡哌酸的固体表面延迟荧光和氟哌酸的室温磷光，不经分离直接测定混合样品中的两种药物获得成功。在ｐＨ约１１的条件下测定吡哌酸的线性范围为５×１０－７ｍｏｌ／Ｌ～３×１０－３ｍｏｌ／Ｌ，测定氟哌酸的线性范围为３×１０－５ｍｏｌ／Ｌ～３×１０－３ｍｏｌ／Ｌ。 Using SrCl2 and Pb (Ac) 2 as selective heavy atom perturbation agents, the delayed fluorescence of the solid surface of pipemidic acid and the room-temperature phosphorescence of norfloxacin were induced, respectively, and the two drugs in the mixed samples were successfully assayed without isolation . The linear range of pipemidic acid was 5 × 10-7mol / L to 3 × 10-3mol / L at a pH of about 11. The linear range of norfloxacin was 3 × 10-5mol / L to 3 × 10 -3mol / L.
