Abstract
Design of an electrochemical adsorption cell utilising Reticulated Vitreous Carbon [RVC] as the working electrode, stainless steel as the counter electrode and a cellulose acetate membrane separator for the sepa ration of 5.4 um polystyrene latex colloidal particles from a KCI solution is described. Effect of variation of flowrate and electrolyte concentratio on the rate of deposition is investigated and the results are compared with Derjaguin-Landau-Verwey-Overbeek [DLVO] predictions for the occurrence of favourable and unfavourable deposition conditions.
