Mn-Catalyzed Oxidation Of Naphthalenediol, G. Whelan, Ronald C. Sims

Biological Engineering Faculty Publications

This study investigates the effects that manganese(IV) dioxide particles have on 2,3-naphthalenediol at varying pH levels (i.e., initial pH of 4.58, 5.85, and 8.75) and under different organic concentration conditions (4×¹⁰⁻³, 4×¹⁰⁻⁴, and 4×¹⁰⁻⁵ M), and assesses the importance of Mn oxides on abiotic catalysis of the multiple-ringed aromatic compound. Proton concentration affected the rates of reductive dissolution; as the pH values increased, the rate of reductive dissolution decreased, as predicted by theory. Also, as the concentration of naphthalenediol increased, the rate of reductive dissolution increased, although not proportionally; thus indicating that a majority of …
