Outline of Final Research Achievements

It is well-known that advanced oxidation processes (AOPs) are used to treat soil and groundwater polluted by chlorinated organic compounds. However, chloromethanes degradation rates of AOPs are low. This study investigated acceleration of photodegradation of chloromethanes with ferritartrate complexes by utilizing winery waste or waste from wild grape juice industry factory. The results showed photodegradation rate of carbon tetrachloride with ferritartrate complexes was increased by gradual leaching of tartaric acid included in particles of waste during photoreaction of ferritartrate complexes.
