The newest results in the chromatographic analysis of non-steroidal anti-inflammatory drugs present in various organic and inorganic accompanying matrices are collected and critically evaluated. Examples for the application of pre-concentration and pre-purification methods for the enhancement of the selectivity and sensitivity of chromatographic technologies are presented. The advantages and disadvantages of the different chromatographic methods are discussed and the separation capacities of the techniques are compared. The application of various chromatographic procedures for the separation and quantitative determination of non-steroidal anti-inflammatory drug (ibuprofen, diclofenac, genfibrozil, ketoprofen, diflunisal, indoprofen, fenoprofen, meclofenamic acid, naproxen, mexiletin) is discussed in detail.

“…Other advantages are the reduced processing time, amount of sorbent, solvent consumption, and reusability of sorbent [ 18 ]. This sample preparation technique has been employed in the analysis of phenolic compounds [ 23 ], perfluorinated compounds [ 25 ], bisphenol A [ 27 ], antiinflammatory drugs [ 30 ], and pesticides [ 28,31 ]. Recently, GO hybrid materials have gained interest in analytical sample preparation.…”

Graphene oxide/Fe3O4 as sorbent for magnetic solid-phase extraction coupled with liquid chromatography to determine 2,4,6-trinitrotoluene in water samples

A fast, simple, economical, and environmentally friendly magnetic solidphase extraction (MSPE) procedure has been developed to preconcentrate 2,4,6-trinitrotoluene (TNT) from water samples prior to determination by liquid chromatography-UV-Vis employing graphene oxide/Fe O nanocomposite as sorbent. The nanocomposite synthesis was investigated, and the MSPE was optimized by a multivariate approach. The optimum MSPE conditions were: 40 mg of nanocomposite, 10 min of vortex extraction, 1 mL of acetonitrile as eluent, and 6 min of desorption in an ultrasonic bath. Under the optimized experimental conditions, the method was evaluated obtaining a preconcentration factor of 153. The linearity of the method was studied from 1 to 100 µg L (N!=!5), obtaining a correlation coefficient of 0.994. The relative standard deviation and limit of detection This is a previous version of the article published in Analytical and Bioanalytical Chemistry. 2017, 409(10): 2665-2674. doi:10.1007 were found to be 12% (n!=!6, 10 µg L ) and 0.3 µg L , respectively. The applicability of the method was investigated, analyzing three types of water samples (i.e., reservoir and drinking water and effluent wastewater) and recovery values ranged between 87 and 120% (50 µg L spiking level) showing that the matrix had a negligible effect upon extraction. Finally, the semiquantitative Eco-Scale metrics confirmed the greenness of the developed method.
