Removal of bio-recalcitrant and toxic compounds from wastewaters has been a major objective of industrial manufacturers for a few years. Due to the potential risk toward public health, regulations are becoming increasingly strict and classical treatments like biological treatments are not efficient. Other techniques such as incineration, oxidation or adsorption provide higher levels of removal ...

The poor mobility of organic pollutants in contaminated sites frequently results in slow remediation processes. Organics, especially hydrophobic compounds, are generally retained strongly in soil matrix as a result of sorption, sequestration, or even formation into non-aqueous-phase liquids and their mobility is thus greatly reduced. The objective of this study was to evaluate the feasibility o...

Visible, near-infrared (NIR) and IR spectra in the 15600-2500 cm(-1) region were measured for phenol and 2,6-difluorophenol, 2,6-dichlorophenol, and 2,6-dibromophenol in n-hexane, CCl(4), CHCl(3) and CH(2)Cl(2) to study hydrogen bonding effects and solvent dependences of wavenumbers and absorption intensities of the fundamental and the first, second, and third overtones of OH stretching vibrati...

Higher fungi have a widespread capacity for biosynthesis of organohalogens. Commonly occurring chloroaromatic fungal metabolites can end up in anaerobic microniches at the boundary of fungal colonies and wetland soils. The aim of this study was to investigate the environmental fate of a major fungal metabolite, 3, 5-dichloro-p-anisyl alcohol, under anaerobic conditions. This compound was incuba...

In this work, the phytoremediation potential of 2,4-Dichlorophenol (2,4-DCP) from soil and wetlands by Datura stramonium L. (jimsonweed) was investigated. The medium seedlings growing in a hydroponic system adjusted to different concentrations (0.0, 75, 100, 125, 150, 175, 200, 225, 250 275 ppm) 2,4-DCP. Four days later, remediation rate 2,4-DCP growth medium, root-stem length, dry weight, lipi...

In this paper, biochar was modified by cetyltrimethylammonium bromide (CTAB) and KOH solution, it characterized TGA, FT-IR, XRD, BET, SEM. Then, the (MB) used to immobilize free laccase (FL) adsorption method prepare (MBL). The degradation performance for 2,4-DCP via MB, FL, MBL were studied. results showed that under optimal conditions, rate of MB on up 42.5%, capacity 85.13 mg/g, proved confo...

Nonylphenol is an endocrine disruptor with harmful effects including feminization and carcinogenesis on various organisms. This study aims to investigate the distribution and ecological risks of nonylphenol in the Daliao River Estuary, China. Nonylphenol, together with other phenolic endocrine disruptors (bisphenol A, 4-t-butylphenol, 4-t-octylphenol, and 2,4-dichlorophenol), was detected in su...
