Single drop micro-extraction with O,O-diethyl dithiophosphate for the determination of lead by electrothermal atomic absorption spectrometry
(2008)
Lead was extracted as the O,O-diethyldithiophosphate (DDTP) complex from aqueous solution into a drop of CHCl3 immersed in the solution.Unlike previously reported procedures using single drop micro-extraction (SDME) for ...
A combination of single-drop microextraction and open tubular capillary electrochromatography with carbon nanotubes as stationary phase for the determination of low concentration of illicit drugs in horse urine
(Elsevier Science, 2011-10-16)
In this study we developed an interesting alternative to HPLC-mass spectrometry for the quantification of seven important drugs of abuse in racehorses. The procedure proposed in this work is a combination of single-drop ...
Electrochemical cell designed for in situ integrate microextraction and electroanalysis: Trace-level determination of norfloxacin in aqueous samples
(2019-05-01)
In this work, a newly designed electrochemical cell was assembled for in situ integrated microextraction and electroanalysis. Ionic liquids (ILs) were used as extractors to perform the microextraction, which enabled the ...

Narrowing the interface between sample preparation and electrochemistry: Trace-level determination of emerging pollutant in water samples after in situ microextraction and electroanalysis using a new cell configuration
(2018-06-10)
In this work, a new cell configuration that enables the in situ integration of sample preparation and electrochemical detection prior analysis at trace-level is described. To perform the microextraction, a green chemistry ...
Development, validation and application of a SDME/GC-FID methodology for the multiresidue determination of organophosphate and pyrethroid pesticides in water
(Elsevier, 2009-10-15)
A single-drop microextraction (SDME) procedure was developed for the analysis of organophosphorus and pyrethroid pesticides in water by gas chromatography (GC) with flame ionization detection (GC-FID). The significant ...
A SDME/GC–MS methodology for determination of organophosphate and pyrethroid pesticides in water
(2011)
A rapid and simultaneousmethod for identification and quantification of pesticides residues in water samples have been developed and applied to the analysis of real samples. Tap and San Francisco River water samples were ...
