Combination of supported liquid membrane and solid-phase extraction for sample pretreatment of triazine herbicides in juice prior to capillary electrophoresis determination

Sensitive determination of herbicides in food samples by nonaqueous CE using pressurized liquid extraction

“…In the past few decades, CE has afforded an analytical tool that is very efficient for the separation of polar and nonpolar pesticides, with short analysis times and minimum use of solvents [25] However, this technique has been little used in the development of methodologies aimed at the analysis of triazines in food samples [26,27]. In this respect, the NACE mode offers a very valid alternative in this field, because it allows the selectivity of the separations to be improved through use of organic media of different polarities [28,29].…”

Determination of additives and organic contaminants in food by CE and CEC

“…Khrolenko et al [58] employed MEKC to determine atrazine in juices. Initially, SPE was used for cleanup and enrichment of the sample, however, for most juices tested the presence of matrix interferences precluded quantitative determination of atrazine.…”

Spectrofluorimetric Method for Quantification of Triazine Herbicides in Agricultural Matrices

“…2 A large number of methods have been reported in the literature for determination of triazine herbicides. These include LCelectrospray ionization mass spectrometry, 4,5 capillary electrophoresis, 6,7 gas chromatography (GC), [8][9][10] GC after liquid-liquid extraction, 11 GC with SPE, 12,13 separation by solid phase extraction-liquid chromatography-UV (SPE-LC-UV), 14,15 molecularly imprinted polymer, 16 dispersive liquid-liquid microextraction method based on solidification of floating organic droplet (DLLME-SFO), 17 HPLC 18 and immunoaffinity chromatography. 19 Most of the methods cited above involve time-consuming sample preparation, complex derivatization and need sophisticated instruments and trained personnel for operation.…”
