  Potentiometric determination of moxifloxacin (Moxi) by ion selective electrode based on ZnO nanorods incorporation with HPβ-CD as sensing ionophore and (KTFPB) potassium tetrakis- (3,5(triflouromethyl) phenyl borate ion as anionic site (additive) in polyvinyl chloride (PVC) membrane, without inner reference solution was developed. The sensor shows nearly nernstian response over a concentration range ( 5 × 10-8 M to 1 × 10-2 M) with a slope of 21.9 ± 0.16 mv decade-1 of concentration with a limit of detection (LOD) 0.127 μM. The electrode exhibits a fast dynamic response of 2 s for a period of 6 months without significant change in its characteristics with excellent stability and sensitivity toward inorganic species. The method is accurate and precise as indicated by the mean recoveries 99.5% with RSD less than 2%. The proposed method was successfully applied.. View More»
