Photoinduced absorption spectroscopy (PIAS) is used to probe the kinetics of oxidation 4-chlorophenol, 4CP, by P25 TiO2 with anodic bias or using a sacrificial electron acceptor and establishes first order for reaction h+ 4CP.

We announce the completion of the genome sequence of a phenol derivative-degrading bacterium, Rhodococcus erythropolis strain CCM2595. This bacterium is interesting in the context of bioremediation for its capability to degrade phenol, catechol, resorcinol, hydroxybenzoate, hydroquinone, p-chlorophenol, p-nitrophenol, pyrimidines, and sterols.

A mutant strain of Azotobacter sp. GP1 converted 4-chlorophenol to 4-chlorocatechol under cometabolic conditions. Under the same conditions the wild-type strain accumulated a yellow compound, which by chemical and spectroscopic methods was identified as 5-chloro-2-hydroxy-6-oxohexadienoic acid (5-chloro-2-hydroxy-muconic semialdehyde). The structure of this compound indicates a meta-proximal cl...

In the present investigation, a ZnO nanostructure was synthesized by means of precipitation and sonochemical methods. The X-ray diffraction (XRD) pattern indicated that the wurtzite structure of ZnO had a hexagonal symmetry and there was no impurity. The average ZnO particles crystallite size was calculated at about 41 nm. The SEM and TEM images revealed nanostructure ZnO particles with a cauli...

The general purpose of this study is to optimise the removal of precursors of taste and odour compounds, especially 2,4,6-chlorophenol, at a water treatment plant. Nowadays, there are frequently problems of taste and odour in drinking water due to the presence of various types of compounds. Some of these are already present in the resource but o thers are generated during the chlorination stage...
