Comparison of the removal of 2,4-dichlorophenol and phenol from polluted water, by peroxidases from tomato hairy roots, and protective effect of polyethylene glycol

Potato Pulp as the Peroxidase Source for 2,4-Dichlorophenol Removal

“…Also, for hairy root cultures, Angelini et al [3] reported, that adding PEG 3350 to the reaction solution improved the efficiency of pollutant removal. However, similarly to González et al [19], we did not observe any statistically significant differences, in the removal efficiency, between the reaction variant with and without PEG supplementation (Fig. 1a, b).…”

Superparamagnetic Fe3O4 nanoparticles as catalysts for the catalytic oxidation of phenolic and aniline compounds

“…In recent years enzymes have been widely studied to remove phenolic and aniline compounds [21][22][23][24][25]. Horseradish peroxidase (HRP) and laccases are proved to be effective to eliminate phenols, biphenols, anilines by catalyzing oxidation in the present of H 2 O 2 to form phenol-or aniline-derived oligomers [26].…”

High-efficiency catalytic degradation of phenol based on the peroxidase-like activity of cupric oxide nanoparticles

“…However, enzyme application was currently hampered by limited natural source, difficult and high-cost purification process, and inherent instability. In order to improve the active life of the enzyme, and thereby a reduction in treatment cost, various efforts have been devoted to find the alternative source, protecting reagent and immobilization method of enzyme on various supports (Cheng et al 2006;Gonzalez et al 2008).…”

“…Due to its high toxicity and hard degradation, phenol has been listed as one of the priority control pollutants by the environmental protection agency in many countries. A variety of techniques such as solvent extraction (Li et al 2004), physical adsorption (Burleigh et al 2002;Dabrowski et al 2005), pervaporation (Hoshi et al 1997), wet air oxidation (Joglekar et al 1991;Chen et al 2001), ozonolysis (Chedeville et al 2007), wet peroxide oxidation (Barrault et al 2000;Kang et al 2002;Calleja et al 2005;Gonzalez et al 2008), electrochemical oxidation (Li et al 2005;Pacheco et al 2007), photocatalytic oxidation (Vione et al 2005;Wang et al 2005), supercritical water gasification (Dileo et al 2007), electrical discharge degradation (Liu and Jiang 2005), and biodegradation (Jiang et al 2006;Ucun et al 2010) have been developed to remove phenol from industrial wastewaters. Each method has its own advantages and disadvantages and can be only applied in speculate conditions.…”
