METHOD FOR PURIFICATION OF SUBSTANCES CONTAMINATED WITH ORGANIC CHEMICALS

摘要

The invention aims at providing a simple and easy method by which many kinds of organic chemicals (contaminants) can be efficiently decomposed in a short time and separated and recovered as insoluble matter. Water or soil contaminated with organic chemicals can be purified by adding a specific metal compound and an ionic transition metal compound to the water or soil, irradiating the resulting water or soil with light to decompose the organic chemicals efficiently into insoluble matter, and separating and recovering the resulting harmless matter.
