Voltammetric techniques have been considered as important methods among the analytical techniques used for the identification and determination of trace concentrations of many biological molecules such as L-ascorbic acid (AA). In this study, ascorbic acid content of some freshly prepared and bottled fruit juices were determined and compared by cyclic voltammetry using carbon paste working electrode. Various factors such as the effect of ascorbic acid concentration on the response of CPE, pH of phosphate buffer solution and some common instrumental parameters on the response characteristics of the electrodes were investigated. From the calibration graph, the relationship between the peak height and ascorbic acid concentration within carbon paste working electrode was investigated. The equation of the calibration graph was found to be: Ip (µA) = 5.034 (mM) + 1.919, R2=0.998, SD= 2.138, n=10. The LOD and LOQ for the developed method were determined to be 0.0221 mM & 0.0735 mM respectively. The degree of recovery for some freshly prepared and bottled fruit juices was calculated by adding standard solution of ascorbic acid to the analyzed fruit juices and the results were found to be in the range between 93.35% - 105.29%.
