Cathodic adsorptive stripping voltammetry of abscisic acid using pencil-lead bismuth-film electrode
In this study, electrochemical behavior of phytohormone abscisic acid (ABA) at the bismuth-film electrode (BiFE) has been investigated using square-wave cathodic stripping voltammetry. BiFE was prepared ex situ on a supporting pencil-lead graphite electrode. ABA yielded a well-defined voltammetric r...
