“…Chlorophenol concentrations in industrial effluents range between 0.5 and 10,000 μg L −1 (Ettala et al 1992;Jank and Fowlie 1980;Melcer and Bedford 1988;Petrasek et al 1983) while they do not exceed 10 μg L −1 in marine environments (Wegman and Hofstee 1979;Jennings et al 1996;Dimou et al 2006). Chlorophenolic compounds have been reported to have toxic effects in marine organisms, including marine phytoplankton, even at very low concentrations (Grimwood and Mascarenhas 1997).…”

“…Residues of all chlorophenol isomers have been found in fresh and marine waters (WHO 1989) including coastal sea waters (Dimou et al 2006;Kot-Wasik et al 2004). The pollution of coastal sea waters by chlorophenols could modify the biota of this environment because these compounds have high toxicity, are recalcitrant, and are accumulated in sediments or at different levels in the trophic chain (Fleming 1995).…”

Removal of p-chlorophenol by the marine microalga Tetraselmis marina

et al. 2007

The ability of Tetraselmis marina, a green coastal microalga, to remove chlorophenols under photoautotrophic conditions was investigated. T.marina was able to grow in the presence of 20 mg L −1 of the phenolic compounds tested. The EC 50 (growth rate) value of p-chlorophenol (p-CP) to T.marina was found to be 25.5 mg L −1 . The microalga was able to remove chlorophenols, showing higher efficiency for p-CP. The effect of photoregime and NaHCO 3 concentration on p-CP removal was investigated. Under continuous illumination with 1 g L −1 NaHCO 3 initial concentration T.marina removed 65% of 20 mg L −1 in a 10-day cultivation period.

“…2,4-Dichlorophenol is mainly used in the production of the herbicide. Although its use has been strictly restrained, there is still a great amount of 2,4-DCP-containing wastewater being drained into the marine environment every year (Pereira et al 1988;Dimou et al 2006;Kot-Wasik et al 2004). …”

Biofilm-electrode process with high efficiency for degradation of 2,4-dichlorophenol

et al. 2010

2,4-Dichlorophenol (2,4-DCP) from chemical industry wastewaters has caused serious environmental pollution. Removal of 2,4-DCP using either physicochemical or biological methods is not very efficient. In this paper, a combination of biological and electrochemical methods gave satisfactory results. By comparisons of the degradation of 2,4-DCP and the removal of chemical oxygen demand (COD) in electrochemical, biological and biofilm-electrode processes, it was found that the biofilmelectrode process possesses the highest degradation efficiency and removal rate; both the pure electrochemical and the pure biological processes were far less efficient. The removal efficiency of 2,4-DCP using the biofilm-electrode process was 100% in 48 h, while that using the pure electrochemical and the pure biological processes were 62 and 42%, respectively. The experiments show that the current of 5 mA for the cathode of 9 cm 2 and the initial concentration 100 mg/l of 2,4-DCP were the optimal parameters of technology for the biofilm-electrode process. The excellent effects are due to the withdrawing electron action of bacterium, electrochemically anodic oxidation and cathodic dechlorination. It is the first time that the biofilm-electrode method was applied in 2,4-DCP degradation. Here, we demonstrated that biofilm-electrode process is a promising method to remove some aromatic compounds in industrial wastewater.

“…Because of the ability to provoke disturbances in the structure of cellular bilayer phospholipids and to cause carcinogenic and mutagenic effects, 2,4‐DCP has been listed as one of the priority control pollutants by the United States Environmental Protection Agency . However, there is still a large volume of 2,4‐DCP contaminated wastewater being discharged into the aquatic environment from various industrial sources . On the other hand, 2,4‐DCP can also be formed from the environmental transformation of herbicides such as 2,4‐dichlorophenoxyacetic acid and 2‐(2,4‐dichloro‐phenoxy)propionic acid, and of the antimicrobial agent triclosan .…”

Background Although the oxidative removal of organic compounds by the Al/O2/acid system has been previously studied, the in situ generation of reactive oxygen species (ROS) and its influencing factors are not well understood. 2,4‐dichlorophenol (2,4‐DCP) is one of the priority control pollutants and widely present in the environment. In this study, the oxidative removal of 2,4‐DCP by the Al/O2/acid system was investigated, especially the in situ generation of ROS and influencing factors. Results More than 90% of 2,4‐DCP was removed within 10 h in pH 2.5 solutions initially containing 10 g L−1 Al and 8.25 mg L−1 dissolved oxygen. The removal of 2,4‐DCP was acid and oxygen driven and was accompanied by the release of chloride ions. While the reduction of oxygen to H2O2 by Al was obtained only under conditions of pH < 4.0, the subsequent Al‐mediated transformation of H2O2 to •OH was achieved under pH < 5.0 conditions. Furthermore, five primary intermediates were identified and oxidation pathways of 2,4‐DCP by the Al/O2/acid system were proposed. Conclusions This work describes a potential method for the removal of 2,4‐DCP in aqueous environments. Oxygen levels and solution pH played important roles in the removal of 2,4‐DCP by Al/O2/acid system. © 2013 Society of Chemical Industry
