Particle impacts are used to quantify the adsorption of catechol on single alumina particles. In these experiments, particles suspended in solution impact a microelectrode held at a suitable potential for the oxidation or reduction of the adsorbed species and the resulting current/time transient spikes associated with individual impacts measured. Using theory for charge diffusion over the surface of a sphere, the individual impact spikes arising from the electro-oxidation of adsorbed catechol can be modeled to derive the diffusion coefficient of charge transfer over the surface of alumina as (2.5 +/- 0.5) x 10(-6) cm(2) s(-1). The coverage of catechol on the surface of alumina is found to be (5.9 +/- 1.9) x 10(-10) mol cm(-2).
