Polymer monolith microextraction using poly(butyl methacrylate-co-1,6-hexanediol ethoxylate diacrylate) monolithic sorbent for determination of phenylurea herbicides in water samples.

Talanta 147 , 199-206, (2015)

In this study, recently developed 1,6-hexanediol ethoxylate diacrylate (HEDA)-based polymeric monoliths were utilized as sorbents for efficient extraction of phenylurea herbicides (PUHs) from water samples. The HEDA-based monolithic sorbents were prepared in ...

Effect of molecular characteristics on the formation of nitrosamines during chlor(am)ination of phenylurea herbicides.

Environ. Sci. Process. Impacts 17 , 2092-100, (2015)

The objective of this study was to investigate the formation of different nitrosamines during chlorination or chloramination (chlor(am)ination) of five phenylurea herbicides (fluometuron, diuron, linuron, metobromuron, and propanil), with the effects of disin...

High efficiency polyethylene glycol diacrylate monoliths for reversed-phase capillary liquid chromatography of small molecules.

J. Chromatogr. A. 1364 , 96-106, (2014)

Highly cross-linked monolithic networks (i.e., polyethylene glycol diacrylate, PEGDA) synthesized from monomers containing varying ethylene oxide chain lengths were fabricated inside fused silica capillary columns for use in liquid chromatography (LC) of smal...

Risk assessment of pesticides detected in surface water of the Alqueva reservoir (Guadiana basin, southern of Portugal).

Sci. Total Environ. 488-489 , 208-19, (2014)

The purpose of this study was to evaluate the potential impact of the pesticides detected in the Alqueva reservoir (Guadiana Basin, South Iberian Peninsula) on the aquatic organisms belonging to this ecosystem. For this purpose, the occurrence and risk assess...
