IAA yielded a well-defined voltammetric response at +0.93 V (vs. Ag/AgCl) in Britton-Robinson buffer, pH 2.0. The process could be used to determine IAA in the concentration range of 5.0 to 50.0 mu M (n=8, r=0.997), with a detection limit of 1.22 mu M. The relative standard deviation of ten measurements was 2.09% for 20.0 mu M IAA. As an example, the practical applicability of BDD electrode was tested with the measurement of IAA in some plant seeds.eninfo:eu-repo/semantics/closedAccessIndole-3-Acetic AcidBoron-Doped Diamond ElectrodeSquare-Wave VoltammetryPlant HormonesArticle233Q2Q2667673WOS:000288093400015
