Effects of some ion-specific properties in the electrocoagulation process with aluminum electrodes

The influence of anion specificity on the faradaic efficiency relative to aluminum oxidation during electrocoagulation has been reported. While with chaotrope anions, is higher than 1, it lower 1 kosmotrope anions. origin this distinction ascribed ability anions cause pitting through thin passive film at surface, which depends varying resistance dehydration. nature cation supporting electrolyte investigated by comparing same treatment two characteristic colloidal samples. removal better for a positively charged latex in presence sodium chloride, negatively oil water emulsion ammonium chloride. results come from different effects pH and its species electrocoagulation.
