The aim of this study was to compare the efficiency of several activated carbons for the removal of chlorite from water. Batch experiments were carried out with 8 powdered activated carbons and with 3 granular activated carbons and by adding every 12 or 24 hours 10 mg of chlorite to 1-liter of phosphate-buffered water ([activated carbon] = 1.0 g l-1). The results showed that the reaction between chlorite and activated carbon yields chloride (as the predominant end-product) and small amounts of chlorate. The capacities of activated carbons for chlorite removal ranged from 400 to 960 mg ClO2 g-1 and depended on the nature of the activated carbon, on the contact time and on the cumulative amount of chlorite added to solutions. Filtration of a distribution water spiked with chlorite ([ClO2-]= 1 mg l-1) through two granular activated carbon columns showed that activated carbon can remove chlorite at interesting capacities for practical applications in drinking water treatment. The efficiency of the two GAC used after a thermal regeneration has also been examined. |
