摘要

Removal or modification of pollutants in industrial or mineral-processing wasteaters by electrosorption at high specific-area carbon materials (felts or powders) has been envisaged in previous work.Electrodes based on high-area substrates behave as quasi-three-dimensional interfaces,thus minimizing diffusion limitation in removal of trace impurities in waters.In the present paper,processes of open-circuit adsorption and electrosorption at electrochemically polarized,high-area C-felt electrode modules are quatitatively examined by means of in situ electrical resitance and optical absorbance measurements made in appropriately designed cells.The effectiveness of the procedures is examined by application to the adsorption and electrosorption of a series of related Scontaining anions and the kinetics of their hydration properties in water.
