Abstract:
The present invention provides a method for purifying organic chemical-containing contaminated substances by which various organic chemicals (contaminants) can be readily and sufficiently decomposed in a short time, the method comprising the steps of adding a metal salt and a transition metal ionic compound to water or soil that contains organic chemicals, decomposing the organic chemicals by irradiating with light, and separating/collecting the detoxified organic chemicals.
