Behaivor of By-products during Direct-photodegradation Treatment of Trichloriethylene.Effect of Oxygen Concentration on Production of By-products

摘要

During direct-photodegradation treatment of trichloroethylene by a low-pressure mercury lamp in a dry air atmosphere,slightly degradable by-products are produced;this production is the most serious issue associated with such treatment.We observed the acceleration of by-products degradation with decrease in an oxygen concentration in a treatment atmosphere.
