Bismuth Nanoparticles Incorporated Centri-voltammetry for Phenol Detection

Abstract

A novel approach has been developed for phenol detection by combining centri-voltammetry with bismuth nanoparticles that are used as carrier reagent. The interaction between bismuth and phenol and also the application of centrifugation provide the effective deposition of phenol onto the electrode surface. Direct voltammetric scan without applying any filtration or decantation prevents the analyte loss. As a result, very sensitive results were obtained with linear ranges of 2-75 mu M and 100-500 mu M and LOD values of 40 nM and 395 nM, respectively. Developed system was also applied for phenol detection in river sample and recovery value was calculated as 115%.
