The reaction rates and orders of azo dye, acid orange 7 (AO 7), oxidation by a Mn oxide containing mine tailings were determined. The reaction is pseudo-first order with respect to the tailings surface area concentration [SA] and pseudo-fractional (0...

Oxidative Decolorization of Acid Azo Dyes by a Mn Oxide Containing Waste (2010)
Journal Article
Clarke, C., Kielar, F., Talbot, H., & Johnson, K. (2010). Oxidative Decolorization of Acid Azo Dyes by a Mn Oxide Containing Waste. Environmental Science and Technology, 44(3), 1116-1122. https://doi.org/10.1021/es902305e

A Mn oxide containing mine tailings, generated in the Kalahari Mn fields, has been shown to oxidatively breakdown acid azo dyes acid orange (AO) 7, acid red 88, acid red 151 and acid yellow 36 but not acid yellow 9. The total reducible Mn content of... Read More about Oxidative Decolorization of Acid Azo Dyes by a Mn Oxide Containing Waste.
