The reaction between chlorite (CO2(-1)) and vanillic acid, at pH 6.0 in the presence of granular activated carbon (GAC), yielded several reaction products identifiable by GC/MS; no products were found in the absence of GAC. Indan and ClO2 or ClO2(-1) reacted in aqueous solution and gave similar products in the presence and absence of GAC. Carbon exposed to ClO2(-1) appears to become capable of promoting hydroxylation, decarboxylation, ring cleavage and CO2 addition reactions with vanillic acid. Chlorite in aqueous solution was reduced by GAC predominantly to Cl(-1). The capacity of one type of virgin GAC for ClO2(-1) reduction to Cl(-1) was about 80-90 mg ClO2(-1)/g GAC before the rate of reaction was sharply reduced.
