ABSTRACT:
Aromatic organic contaminants in waste water efficiently removed by oxidizing the contaminants with hydrogen peroxide in the presence of a catalytic amount of ferrous ions, at an acid pH, to produce an oxidized water which may be passed through activated carbon to adsorb residual organic contaminants; the process is especially useful for treatment of contaminated water derived from a wood preservation treatment and containing polyaromatic hydrocarbons and phenols and/or chlorinated phenols.
