Abstract
A method is provided for detecting the presence of organic materials in an aqueous sample. The materials are decomposed by simultaneous exposure to ultraviolet radiation and acoustic energy to decompose the materials to simple decomposition products. The simple decomposition products such as ammonium ion, halogen ion, alkyl ammonium ions, or sulfate ions, are then detected by conventional analytical devices and methods.
