Abstract

The adsorption on a mercury/aqueous solution interface of poly(ethylene glycol)s (PEGs) with molecular weights from 200 to 20 000 was studied by a.c. voltammetry in order to understand better the adsorption of linear components of fulvic acids on hydrophobic particles in natural waters, and the influence of their adsorption on voltammetric signals. As a general trend it was noted that the equilibrium adsorption constant increases with the molecular weight while the adsorption rate decreases. The values of the maximum surface concentration F. suggest a flat configuration for adsorbed molecules for all PEGs studied.
