Since they often inhibit abundant bacteriological populations in municipal wastewater treatment plants, alternative treatment methods should be investigated – including advanced oxidation processes. This paper studies the degradation of three representatives of phenolic compounds using the Fenton system in the presence of chlorides and sulfates: phenol, 2-chlorophenol and 2-nitrophenol. The pre...

An equimolar reaction of 5-chlorosalicylaldehyde and 2-bromo-4-chloroaniline yielded the Schiff base ( Z )-2-((2-bromo-4-chlorophenyl)imino)methyl)-4-chlorophenol) (HL), which was used for complexation to Co 2+ , Ni Cu Zn metal salts.

Arthrobacter chlorophenolicus A6, a previously described 4-chlorophenol-degrading strain, was found to degrade 4-chlorophenol via hydroxyquinol, which is a novel route for aerobic microbial degradation of this compound. In addition, 10 open reading frames exhibiting sequence similarity to genes encoding enzymes involved in chlorophenol degradation were cloned and designated part of a chlorophen...

The electrical decomposition of 4-chlorophenol in water was examined with iridium dioxide doped on atitanium electrode. A number of electrical degradation products of 4-chlorophenol, such as hydroquinone and chlorohydroquinone via the addition of hydroxyl radicals, and dichlorophenol through addition of chlorine radical, were observed as major products. Moreover, hydroxylated chlorobiphenylethe...

fertilizer plant waste carbon slurry has been investigated after some processing as an adsorbent for the removal of dyes and phenols using columns. the results show that the carbonaceous adsorbent prepared from carbon slurry being porous and having appreciable surface area (380 m2/g) can remove dyes both cationic (meldola blue, methylene blue, chrysoidine g, crystal violet) as well as anionic (...

The intermolecular hydrogen bonding interaction between p-chlorophenol and amyl acetate has been investigated by FT-IR spectroscopy. This article mainly reports the results of p-chlorophenol with carbon tetrachloride solution and in the presence of amyl acetate. The spectroscopic characteristics of OH....O complexes are specified. Also, the formation constant for 1:1 and 1:2 complexes at 25 C w...

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...
