Abstract : The adsorption of thiourea at mercury from ethylene carbonate solutions containing 0.5 KPF6 and varying amounts of thiourea has been studied by measuring the differential capacity of the polarisable interface as a function of potential. The data were analyzed to obtain the surface excess of thiourea as a function of electrode potential and bulk concentration. The parameters characterizing the adsorption isotherm are discussed in terms of the electrostatic model for dipole adsorption by Kir'yanov, Krylov and Damaskin. These parameters are also compared with those obtained previously for the adsorption of thiourea from water, methanol, formamide, and dimethylformamide. (Modified author abstract)
