Two Schiff base compounds with similar backbone, but different positions and lengths of alkyl groups, (E)-4-(((4-propylphenyl)imino)methyl)phenol (PMP) and (E)-4-((2-tolylimino)methyl)phenol (TMP) have been synthesized. Their structures were established by spectroscopic techniques which include ...

A series of bismuth incorporated MCM-41 mesoporous samples were synthesized and characterized by inductive coupled plasma emission spectrometer (ICP), X-ray diffraction, N2 adsorption/desorption, transmission electron microscopy, and UV-Vis spectroscopy. These samples catalyzed the selective oxi...

Degradation of toluene and 4-chlorotoluene in air mixture was studied by using electron beam generated plasma reactor. It was found that removal efficiency of toluene and 4-chlorotoluene was influenced by radiation dose, i.e. energy deposited in the gas, and their initial concentration. The by-p...

The solubility of 4-chlorotoluene in subcritical water was measured using an optically transparent fused silica capillary reactor (FSCR). The total dissolution temperature of 4-chlorotoluene in subcritical water was visually determined. The dissolution uniformity of 4-chlorotoluene in subcritica...

Bromophenol is listed as a priority pollutant by the U.S. EPA. However, there has been no report on the removal of bromophenol in any biological system that is operated in a continuous mode. The efficiency of Arthrobacter chlorophenolicus A6T on the biodegradation of 4-bromophenol (4-BP) in a ne...

An EDTA enhanced bimetallic Al0–Fe0/O2 process was proposed for spontaneous in situ production of H2O2 and OH to rapidly oxidize 4-bromophenol. The effects of EDTA on Al0/O2, Fe0/O2 and Al0–Fe0/O2 system were investigated. The mass ratio of Al0 and Fe0 was also optimized. The role of EDTA enha...

Halogenated aromatic compounds have attracted increasing concerns due to their toxicity and persistency in the environment, and dehalogenation is one of the promising treatment and detoxification methods.
