Електрохімічна оцінка відновлювальної здатності рослинних екстрактів

Abstract

Agricultural by-products are widely used as a source of cheap and environmentally friendly reagents in “green” chemistry. The chemical composition and reducing ability of water extracts of black currant, grape and apricot wastes were studied. Application of LC-MS revealed that all the extracts contained large amount of natural reducing agents – polyphenols and flavonoids. The electrochemical technique of cycling voltamperometry was used to investigate the reducing ability of the extract. Recorded voltamperograms shoved anodic current rise at the potentials above +0.4 V/SSCE meaning the extracts can be used as reducing agents in green synthesis of silver nanoparticles.
