Abstract

Abstract Using the voltammetry of microparticles approach, the electrochemical response of complexes prepared with indigo plus different clays in contact with aqueous electrolytes is described. Indigo presents a strong attachment with palygorskite and sepiolite in contrast to a weak attachment to planar clays (montomorillonite and kaolinite). Cyclic voltammetric and chronoamperometric data provide estimates of the variation of the concentration of indigo ...
