Adsorption of pentaerythritol at the mercury/aqueous sodium fluoride interphase
Abstract
The adsorption of pentaerythritol [2,2-bis(hydroxymethyl)propane-1,3-diol] at mercury from aqueous NaF has been studied using measurements of double-layer capacity and electrocapillary curves. The concentration dependence of the adsorption can be represented by a Frumkin isotherm with a repulsive interaction parameter. Its behaviour is compared with that of other polyhydroxy compounds.
