| Abstract: | The voltammetric behavior of Ceftazidime(CTD) has been studied. Two irreversible adsorpted reduction peaks involving one electron (p1) and two electron, one proton(p2) were obtained in the medium of phosphate buffer (pH 3. 5). The peak potential was at - 0. 65 V(p1) and - 1 .20 V(p2) (vs. SCE). The mechanism of electrode reduction was discussed. A sansitive method for the determination of CTD by single-sweep oscillopolarography was developed. The method was applied to the determiantion Of CTD in urine with satisfactory result. |
