BIODEGRADATION KINETICS OF 4-CHLOROPHENOL, AN INHIBITORY CO-METABOLITE
(WATER ENVIRONMENT FEDERATION, 1991)
Kinetic experiments were performed with batch reactors containing a pure culture of Psedomonas putida PpG4 and 4-chlorophenol as the only organic substrate present. 4-Chlorophenol behaved as a cometabolite because its ...
Photocatalytic degradation of 2-chlorophenol by tio2: kinetic studies
(Planta Piloto de Ingeniería Química, 2013-01)
Kinetic studies of 2-chlorophenol photocatalytic degradation are carried out in a batch stirred built in quartz laboratory scale, using TiO2 as catalyst photoactived with ultraviolet light. Experimental design is ...
Electrooxidation of 2-chlorophenol and 2,4,6-chlorophenol on glassy carbon electrodes modified with graphite- zeolite mixtures
(2014)
This work reports the behavior of zeolite-graphite electrodes for the oxidation of 2,4,6-trichlorophenol (2,4,6-TCP) and 2-chlorophenol (2-CP) in a pH 3, 0.5 M Na2SO4 electrolyte using cyclic voltammetry, chronoamperometry, ...
Antimicrobial endodontic compounds do not modulate alkylation-induced genotoxicity and oxidative stress in vitro
(2006-08-01)
Objective: To investigate if formocresol, paramonochlorophenol, or calcium hydroxide modulate the genotoxic effects induced by the oxidatively damaging agent hydrogen peroxide (H 2O 2) or the alkylating agent methyl ...
Effect of dentine surface treatment on leakage of root fillings with a glass ionomer sealer.
(1995-07-01)
The purpose of this study was to observe the quality of seal of the glass ionomer cement, Ketac-Endo, after treatment of the root canal wall. The root canals of 140 extracted human teeth were prepared biomechanically. The ...
