“…30,31 Its use is widespread in many analytical applications, such as environmental analysis, [32][33][34] food, [35][36][37][38][39][40] aromatic, [41][42][43] forensic [44][45][46] and pharmaceutical. [47][48][49] Also, low detection limits can be easily reached with this technique due to their ability in preconcentration of analytes, 50 since it uses a polymeric coating which favors extraction.…”

This paper investigates a strategy as a quality control parameter, using standard surrogate and determination of a relation factor for determination of parathion-methyl, chlorpyriphos and cypermethrin pesticides in environmental aqueous matrices with distinct characteristics (river water, estuarine, seawater and weir water), using the technique of solid phase microextraction gas chromatography with flame ionization detector (SPME-GC-FID). Pesticides were very susceptible to matrix effects promoted by environmental samples. The salinity and the organic matter seem to have been the main sources of interference in the method. For chlorpyriphos, in middle and high levels, the values of relation factor (R f ) for estuarines, seawater and weir matrices were statistically similar. For cypermethrin, the statistical equality occurred in estuarine matrices in medium and high levels of concentration. That indicates proportional behavior between the pesticide and the surrogate recovery, suggesting that a single value of R f can be used as correction factor recovery for any of these matrices.

“…The detected concentrations of chlorophenols in freshwaters and drinking waters range from low nanograms per liter to low micrograms per liter (Kawaguchi et al 2005;Elci et al 2011), while they occur at nanograms per liter to micrograms per liter, even up to milligrams per liter, in wastewaters (Quintana et al 2007;Regueiro et al 2009;Limam et al 2010). Although the member countries of European Union (EU) have restricted the use of chlorophenols, they are still widely used in many countries, including the United States (US) and China (Holopainen et al 2013;Igbinosa et al 2013).…”

Sorption of 2-chlorophenol (2-CP), 2,4-dichlorophenol (2,4-DCP), and 2,4,6-trichlorophenol (2,4,6-TCP) on a range of dealuminated zeolites were investigated to understand the mechanism of their sorption on microporous minerals, while the influence of common metal cations, solution pH, and humic acid was also studied. Sorption of chlorophenols was found to increase with the hydrophobicity of the sorbates and that of the microporous minerals, indicating the important role of hydrophobic interactions, while sorption was also stronger in the micropores of narrower sizes because of greater enhancement of the dispersion interactions. The presence of metal cations could enhance chlorophenol sorption due to the additional electrostatic attraction between metal cations exchanged into the mineral micropores and the chlorophenolates, and this effect was apparent on the mineral sorbent with a high density of surface cations (2.62 sites/nm 2 ) in its micropores. Under circum-neutral or acidic conditions, neutral chlorophenol molecules adsorbed into the hydrophobic micropores through displacing the Bloosely bound^water molecules, while their sorption was negligible under moderately alkaline conditions due to electrostatic repulsion between the negatively charged zeolite framework and anionic chlorophenolates. The influence of humic acid on sorption of chlorophenols on dealuminated Y zeolites suggests that its molecules did not block the micropores but created a secondary sorption sites by forming a Bcoating layer^on the external surface of the zeolites. These mechanistic insights could help better understand the interactions of ionizable chlorophenols and metal cations in mineral micropores and guide the selection and design of reusable microporous mineral sorbents for sorptive removal of chlorophenols from aqueous stream.

“…SPME has been directly coupled to IMS instruments with 63 Ni or corona discharge as the ionization source [37,38]. Mohammad T. [32] designed a new desorption chamber to have the direct introduction of SPME fiber into the electrospray solvent flow, making direct introduction of liquid samples into IMS possible.…”
