Photochemical Studies on Degradation of Cetyl Pyridinium Chloride (Cationic Surfactant) in Aqueous Phase Using Different Photocatalysts
The photocatalytic process using semiconductors with a nanostructure is one of the technologies usedfor the destructive oxidation of organic compounds such as surfactants. In this paper, thephotocatalytic degradation of Cetyl pyridinium chloride (CPC), was investigated in aqueous phaseusing various semiconductors such as titanium dioxide (Ti02), zinc oxide (ZnO), stannic oxide(Sn02). The degrad...

متن کاملPhotocatalytic Degradation of 4-Chlorophenol. 2. The 4-Chlorocatechol Pathway
The TiO2-mediated photocatalytic degradation of 4-chlorocatechol is studied as a branch of the degradation of 4-chlorophenol. In addition to some basic kinetic studies, the identities of many of the cyclic and acyclic intermediates, verified in most cases with authentic samples, are reported. From 4-chlorocatechol, the major product is hydroxylation to form 5-chloro-1,2,4-benzenetriol. A small ...
متن کاملPhotocatalytic degradation of 4-chlorophenol by UV/H2O2/NiO process in aqueous solution
The removal of 4-chlorophenol from aqueous phase continues to be an important environmental issue. In this work, the photochemical oxidation of 4-chlorophenol in aqueous solutions in a batch reactor using ultraviolet irradiation, hydrogen peroxide and nickel oxide was studied. The efficiency of the system was evaluated with respect to reaction time, pH, feed concentration of reactants, catalyst...
متن کاملSeparation of methacrylic acid from aqueous phase using quaternary amine
The feasibility of extractive reaction of methacrylic acid from aqueous solution using a quaternary amine, tri–octyl methyl ammonium chloride (TOMAC) as an extractant, was studied. The diluents chosen in the present work belong to different chemical classes, n–butyl acetate, carbon tetrachloride, isoamyl alcohol, methyl isobutyl ketone, and toluene. The effect of initial acid concentration in t...
