This work is of particular interest, given the growing concern of legislators, public health officials, and environmental groups about the deleterious environmental impact of halogenated oxidants. The goal of this research is to examine polyoxometalates that can potentially catalyze the oxidation, or bleaching, of stains such as ink, pinacyanol chloride dye (monomer, ë max = 600 nm; dimer, ë max = 550 nm; [varepsilon] = 38,800) by hydrogen peroxide in basic water at room temperature, thus obviating the need for chlorine-containing oxidants. Base-stable niobium containing polyoxometalates covalently attached to oxidizing cations such as iron (III) were investigated. |
