Abstract
The adsorption of thiourea from solutions of nitromethane, saturated w ith KPF6 was studied in a function of temperature by the impedance met hod. The adsorption parameters of Frumkin's isotherm were analysed as a function of temperature and the electrode charge density. Quasi-soli d condensates of thiourea are not formed at the electrode. Adsorbed th iourea reorients the nitromethane dipoles, changing considerably the e lectrostatic parameters of the inner layer.
