“…The highest removal efficiencies were observed for the 3,4‐ and 3,5‐DMP isomers and the lowest for 2,6‐DMP . Intermediates resulting from the DMP degradation (such as dimethylbenzenediols and ketoadipic acid carboxylates) and oxidative coupling products (such tetramethyl‐[1,1’‐biphenyl] diols and tetramethyl diphenylether monools) were found in small amounts . The abiotic sorption potential of the roots of Juncus effusus toward different phenolic compounds, including DMPs and polycyclic aromatic hydrocarbons, was also studied .…”

Phenolic compounds in industrial wastewaters are toxic pollutants and pose a threat to public health and ecosystems. More recently, focus is being directed toward combining the treatment of these compounds with a cost‐effective and environmentally sound technology. The removal efficiency of dimethylphenol and ammonium nitrogen was studied, for the first time, in three different laboratory‐scale horizontal subsurface flow constructed wetlands planted with Juncus effusus. Two of the wetlands used were filled with gravel. One of these was planted and the second left without vegetation. The third wetland was a hydroponic system. It was found that the removal efficiencies of dimethylphenol was dependent on the inflow loading of the contaminant and was higher in the planted systems. Both planted systems yielded 99% removal efficiency up to loads of 240 mg/d, compared to only 73% for the unplanted constructed wetland. Factors and processes such as redox dynamics, methanogenesis, reduction of ammonium and low nitrate and nitrite concentrations imply simultaneous aerobic and anaerobic dimethylphenol transformations. A significant surplus of organic carbon was detected in the planted wetlands, which may originate from intermediates of the dimethylphenol transformation processes and/or organic plant root exudates. The present study demonstrates that horizontal subsurface flow constructed wetlands are a promising alternative system for the treatment of effluents contaminated with dimethylphenol isomers.

“…Selection of a fiber coating depends on the properties of the compounds and the coatings. PDMS coating is preferred by nonpolar compounds such as PAHs [37], polybrominateddiphenyl esters (PBDEs) [34], OCCs [29], and organochlorine pesticides (OCPs) [38,39] while polyacrylate (PA) coating is usually used for relatively polar compounds such as phenols [37], alcohols [32,40,41], organophosphate ester [30], surfactants [25,[42][43][44], and anilines [45]. On the other hand, when the volume ratio of the fiber coating to the sample is constant, fibers with low K ff value can be chosen as an alternative option when the sensitivity is allowed.…”

“…However, if at a steady state, net desorption from the matrix can re-establish and reach equilibrium, and the concentration on the fiber is still proportional to the initial freely dissolved concentration. Matrix-SPME has been applied by Mayer et al to measure freely dissolved concentrations in sediment pore water [37]. It is preferable to apply matrix-SPME at equilibrium, but kinetic measurements can be performed when the equilibrium between matrix-bound and freely dissolved analytes is established much more quickly than the extraction equilibrium, so the equilibrium condition is met.…”

Ever since its invention, solid phase microextraction (SPME) has been widely used for aqueous sampling. In recent years, this technique has received increasing attention for the analysis of complex water sample because of its capability of sensing freely dissolved analytes in the complex matrix. In this chapter, the development of negligible depletion SPME (nd-SPME) for the determination of freely dissolved analytes in complex water samples is reviewed. The fundamentals and sampling conditions of nd-SPME are first discussed. Then, the application of nd-SPME for measurement of sorption coefficients in complex matrixes is summarized. In addition, the calibration methods of nd-SPME are discussed in detail, especially the effect of complex matrix on the sampling kinetic. For the first time, the advances of complex matrix effects including retarded and enhanced effects on the SPME sampling kinetic are fully explored.

“…SPME has been used for numerous applications, including environmental [14][15][16][17] and biological samples determinations [18][19][20][21]. SPME can be used for either the direct extraction of analytes by exposing the fiber coating to gases or liquid samples, or the indirect extraction from the gaseous headspace above the sample medium [13].…”
