TL;DR: The results obtained show that the MIP-based approach to the solid-phase extraction is comparable with the more traditional solid- phase extraction with C18 reversed-phase columns in terms of recovery, but it is superior in Terms of sample clean-up.

TL;DR: In this article, vancomycin has been used as chiral selector for the enantiomeric separtion of several free acid herbicides, namely aryloxypropionic (mecoprop, fenoprop and dichlorprop), N -benzoyl- N -(3-chloro-4-fluorophenyl)-2-aminopropionic acid (flamprop) and arylooxyphenoxypropionionic (haloxyfop, fluazifop, diclofop and f

TL;DR: Capillary electrophoresis conditions in the free solution mode were established for the separation and detection of 2,4-dichlorophenoxyacetic acid and three optically active phenoxy acid herbicides as discussed by the authors.

TL;DR: In this article, different structural changes in peat humic acid (HA) were induced through treatments leading to chemical derivatization and/or the removal of functional groups and the most intense interactions occurred in samples from the neutral plot, whereas the greatest effect of the humic matter in enhancing pesticide sorption was found with the calcic soil.
Abstract: Summary
Different structural changes in peat humic acid (HA) were induced through treatments leading to chemical derivatization and/or the removal of functional groups. Eleven humic products were obtained after acetylation, amidation, ammonia fixation, methylation, nitration, oximation, sulphonation, selective degradations and ‘fixation’ of stearic acid. The sorption of 12 pesticides (alachlor, atrazine, carbofuran, 2,4-D, 2,4-DB, methyl parathion, metoxuron, monouron, prometryne, propanil, fenoprop and chloranil) on the above products was determined by ultraviolet derivatographic spectroscopy. In addition, pesticide sorption was evaluated on samples from neutral and calcic soils treated with the corresponding potassium humates. The most intense interactions occurred in samples from the neutral plot, whereas the greatest effect of the humic matter in enhancing pesticide sorption was found with the calcic soil. As expected, the sorption patterns in HA-pesticide systems were poorly correlated with those in soil-HA-pesticide systems. In the former case, the sorption performance was influenced mainly by hydrophobic interactions, whereas in the latter it depended on the participation of multiple parameters suggesting that the molecular volume and the van der Waals energy of the pesticide molecule play a chief role. The HA characteristics most frequently correlated with pesticide sorption were those connected with the aromatic/aliphatic ratio and the particle size. In the calcic-soil-HA-pesticide systems, the base saturation of the exchange complex correlated negatively with pesticide sorption.
