Abstract

The technical concept of this technique uses two strong oxidants in a combined treatment approach that utilizes each oxidant's uniquely different oxidizing properties in a complementary and augmentative manner. The technique provides the capability to oxidize organics in an aqueous solution by alternately adding the two oxidants Chlorine Dioxide (ClO2) and Potassium Permanganate (KMnO4) in sequence. It is based on the knowledge that ClO2 will react with organics containing the Hydroxyl (OH) group and will oxidize these organics to their respective organic acids and that KMnO4 will then react with these organic acids and will further oxidize them to Carbon Dioxide (CO2) and water.

Oxidation of Organics With Oxidants Chlorine Dioxide and Potassium Permanganate

The technical concept of this technique uses two strong oxidants in a combined treatment approach that utilizes each oxidant's uniquely different oxidizing properties in a complementary and augmentative manner. The technique provides the capability to oxidize organics in an aqueous solution by alternately adding the two oxidants Chlorine Dioxide (ClO2) and Potassium Permanganate (KMnO4) in sequence. It is based on the knowledge that ClO2 will react with organics containing the Hydroxyl (OH) group and will oxidize these organics to their respective organic acids and that KMnO4 will then react with these organic acids and will further oxidize them to Carbon Dioxide (CO2) and water. The combination of these two oxidants in an alternating sequence provides the means to treat and remove low concentrations of alcohols, glycols, phenols, aldehydes, acids, etc., from an aqueous solution. Low concentrations of water- soluble organic solvents containing the OH group in an aqueous solution can be readily oxidized to their respective organic acids through the addition of ClO2 . ClO2 should be added to the solution at a rate which minimizes the loss factor due to the low solubility of ClO2 in an aqueous solution and the method utilized for the reaction. The amount to be added should be slightly excessive of the stoichiometric amount equivalent to that required to react with the total quantity of r...
