A Review: Stripping Voltammetric Methods as a High Sensitive Strategy for Trace Analysis of Ions, Pharmaceutical and Food Samples

Electrochemical techniques are powerful tools for trace analysis of important food, clinical and environmental compounds in real samples. In between electrochemical methods, stripping voltammetry technique is a very selective and highly sensitive method for the determination of nanomolar level of electroactive species in solution. Detection limits for electroactive compounds at sub-ppb concentrations have been reported using stripping voltammetric methods. Therefore, in this review, we focus on application of stripping voltammetric sensor for trace level analysis of metal ion, drug and environmental compounds. This review describes basic stripping voltammetric sensors and ability of them in the real sample analysis. Stripping voltammetric sensors can be used in industry for the analysis of food samples and they are a good alternative for HPLC method. Fast response and good limit of detection are the main reason that encourages us to write a review.
