环丙沙星－锰络合吸附波的研究①张加玲樊惠芝潘景浩＊（山西大学化学系，太原０３０００６）环丙沙星（ｃｉｐｒｏｆｌｏｘａｃｉｎ简写ＣＰＦＸ）是新一代氟喹诺酮类抗菌药物之一，它的抗菌力强、抗菌谱宽，临床应用非常广泛．关于氟喹诺酮类抗菌药物与抗酸剂、维生素类...In 0.1 mol·L -1 NH 3 NH 4Cl buffer solution(pH 9.2),a sensitive reduction peak of complex of ciprofloxacin (CPFX) with manganese (Mn) was obtained by single sweep oscillopolarograph. The peak potential( Ep ) is -1.61 V(vs.SCE). The peak current ( i p) is proportional to the concentration of Mn(Ⅱ) over the range of 5×10 -6 ～2×10 -5 mol·L -1 . It is possible to be applied to the determination of Mn(Ⅱ). The polarographyic and voltammetric behaviour of complex was studied in detail. The ratio of CPFX∶Mn in the complex was 2∶1. The electrode reaction mechanism was discussed.
