Abstract

This work introduce an easy and fast continuous cyclic voltammetric technique for the propose monitoring of ultra trace amounts of salbutamol in a flow-injection system. The potential waveform, which consisted of the potential steps for cleaning, stripping and potential ramp, was continuously applied on an Au disk microelectrode (with a radius of 12.5mum). The detection method we propose has some advantages, the greatest of which are: (1) removing oxygen from the analyte solution is no longer necessary, and (2) it is a very fast and appropriate technique for the determination of the drug compound in a wide variety of chromatographic analysis methods. The detection limit for salbutamol was 2.0x10(-9)M. The relative standard deviation (R.S.D.) of the proposed technique at 10ng/mL was 3.5% for 10 runs. The effects of pH of eluent, accumulation potential, sweep rate, and accumulation time on the sensitivity of the method for the determination of the salbutamol were investigated. The proposed method was applied to the determination of salbutamol in pharmaceutical preparation and biological samples.
