Differential Electrolytic Potentiometry: A Detector for Flow Injection/Sequential Analysis in Complexation Reactions

Abstract

Differential electrolytic potentiometry is applied as an indicating system for the determination of ciprofloxacin using flow injection/ sequential injection analysis configuration. The behaviour of silver electrodes, platinum electrodes, silver amalgam electrodes and platinum amalgam electrodes has been investigated. The optimim conditions of type of electrodes, flow rate, volume of sample, the magnitude of the current, the coil length, the concentration of the reagent and the concentration of sulphuric acid all has been investigated. A normal calibration curve is applicable for the determination of ciprofloxacin in formulated drugs has been obtained. The advantage of differential electrolytic potentiometry as a detector for flow injection or sequential analysis is reported.
