Determination of priority carcinogenic polycyclic aromatic hydrocarbons in wastewater and surface water by coacervative extraction and liquid chromatography-fluorimetry
(Elsevier, 2008)
The US Environmental Protection Agency (EPA) and the European Union (EU) have set restrictive limits for priority carcinogenic polycyclic aromatic hydrocarbons (CPAHs) in surface waters (EPA 3.8 ng L−1and EU 2–100 ng L−1) ...
Coacervative extraction of Ochratoxin A in wines prior to liquid chromatography/fluorescence determination
(Elsevier, 2008)
Coacervates made up of reverse micelles of decanoic acid were assessed as a new strategy
for the simplification of wine sample treatment in the determination of Ochratoxin A (OTA).
Simultaneous extraction/concentration ...
Determination of bisphenols A and F and their diglycidyl ethers in wastewater and river water by coacervative extraction and liquid chromatography–fluorimetry
(Elsevier, 2007)
A simple, rapid and sensitive analytical method was developed for the simultaneous determination of bisphenol A (BPA), bisphenol F (BPF) and their corresponding diglycidyl ethers (BADGE and BFDGE) in wastewater and river ...
Potential of supramolecular solvents for the extraction of contaminants in liquid foods
(Elsevier, 2009)
Supramolecular solvents, which are water immiscible liquids consisting of supramolecular aggregates in the nano- and micro-scale regimes dispersed in a continuous phase, were assessed for the extraction of trace contaminants ...
Hemimicelles of Alkyl Carboxylates Chemisorbed onto Magnetic Nanoparticles: Study and Application to the Extraction of Carcinogenic Polycyclic Aromatic Hydrocarbons in Environmental Water Samples
(ACS, 2009)
In this work, magnetic nanoparticles (MNPs) coated with hemimicelles of alkyl (C10-C18) carboxylates, which have traditionally been used to prepare ferrofluids for technological applications, were used for the first time ...
