Photo-Fenton Degradation of Pentachlorophenol: Competition between Additives and Photolysis

Efficiency of Photo-Fenton Process in Degradation of 2-Chlorophenol

Background & Aims of the Study: Phenolic compounds have been extensively used in industries for applications such as petrochemical, oil refineries, papers, plastics, steel, pharmaceuticals, textiles, coal conversion, and so on. Specified amounts of Phenolic compounds are lost in the process of their manufacturing and utilization and often cause environmental pollution problems....

Photo-Catalytic Degradation of an Oil-Water Emulsion Using the Photo-Fenton

Degradation of crystal violet using copper modified iron oxide as heterogeneous photo-fenton reagent

The heterogeneous photo-Fenton degradation of crystal violet under visible light has been investigated usingcopper modified iron oxide. The photocatalyst has been prepared by coprecipitation method. The rate ofphotocatalyic degradation of dye was monitored spectrophotometrically. It has been observed thatphotocatalytic degradation follows pseudo first order kinetics. The effect of various param...

Biodegradation and photolysis of pentachlorophenol in artificial freshwater streams.

The biodegradation, photolysis, and adsorption of pentachlorophenol (PCP) in outdoor, aquatic environments were examined with man-made channels built by the U.S. Environmental Protection Agency at a field station on the Mississippi River near Monticello, Minn. Four channels were used, each channel being approximately 520 m long and receiving river water that flowed through the channels for abou...
