✦ Synopsis
The dependence of adsorption of chlorobenzene at the gold/electrolyte (0.5 M H2S04) interface on electrode potential, bulk concentration and temperature has been investigated using a "'C-radiotracer technique. For higher bulk concentrations of chlorobenzene, multilayer adsorption has been observed. It has been shown that the diffusion is the rate determining step of the adsorption process. The chlorobenzene molecule are probably perpendicularly orientated to the Au surface and the chlorine atom of the molecule is contacting the gold electrode.

The double layer capacitance was measured on gold-bead electrodes in N,-stirred 2 N Na,SO, solution as a function of the pre-treatment of the gold surface. Such measurements are sensitive to small quantities of adsorbed oxygen. It is suggested that oxygen may be adsorbed in rather small quantities o
The sorption behavior of chlorobenzene on marine sediments treated by different methods was investigated. Through experiments on three factors (temperature, sediment organic carbon content, and media) that might affect the sorption behavior of chlorobenzene, some important conclusions were obtained.
