Abstract
A method is described for the determination of minute amounts of indol e-3-acetic acid (IAA) in plant extracts. The method is based on adsorp tive stripping voltammetry at a carbon fiber ultra microelectrode. Opt imal conditions with respect to accumulation time and potential, scan rate and pH are established. The relative error was 1.6% and the relat ive standard deviation was 1.5% for IAA concentrations at the 1.O mu g ml(-1) level.
