ABSTRACT:
A waste water cleanup process where an aqueous solution of organoboron compounds is hydrolyzed to boric acid and the corresponding organic compound by treatment at a temperature of greater than 150.degree. C. at a pressure sufficient to prevent substantial evaporation and at a pH of 5 or greater, but 9 or less.
