This book was released on 1992 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salting-out solvent extraction (SOE) was compared with cartridge and membrane solid phase extraction (SPE) for preconcentration of nitroaromatic and nitramine explosives from water, prior to reversed-phase high performance liquid chromatographic analysis (RP-HPLC). The procedures were compared initially using reagent grade water fortified with TNT, RDX, HMX and nine other analytes at concentrations below what could be determined without preconcentration and the results were used to estimate analyte recovery and the low concentration detection capability, as characterized by the Certified Reporting Limit (CRL). CRLs for the three procedures were comparable with values generally in the range of 0.05 to 0.30 jig/L. Percentage recoveries for the three procedures were generally greater than 90%, except for those of HMX and RDX obtained by the membrane-SPE procedure. A second comparison among the three procedures was obtained on 58 groundwater samples from the Rockeye site at the Naval Surface Warfare Center, Crane, Indiana. Results from a direct analysis procedure were compared to those from the three preconcentration techniques to estimate percent recovery of HMX, RDX and TNT for real samples. Recoveries were greater than 80% except for HMX and RDX by the membrane-SPE method. Both SPE procedures exhibited background interferences, which the authors attribute to matrix interaction with the SPE polymers. Usability of the three procedures in a production-oriented laboratory was evaluated with emphasis on solvent consumption, waste production and sample processing time. The cartridge-SPE was judged to be the least rugged of the three procedures.

This book was released on 2019-07-11 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of 13 innovative papers describing the state of the art and the future perspectives in solid-phase extraction covering several analytical fields prior to the use of gas or liquid chromatographic analysis. New sorptive materials are presented including carbon nanohorn suprastructures on paper support, melamine sponge functionalized with urea–formaldehyde co-oligomers, chiral metal–organic frameworks, UiO-66-based metal–organic frameworks, and fabric phase sorptive media for various applications. Solid-phase extraction can be applied in several formats aside from the conventional cartridges or mini-column approach, e.g., online solid-phase extraction, dispersive solid-phase microextraction, and in-syringe micro-solid-phase extraction can be very helpful for analyte pre-concentration and sample clean-up. Polycyclic musks in aqueous samples, 8-Nitroguanine in DNA by chemical derivatization antibacterial diterpenes from the roots of salvia prattii, perfluoroalkyl substances (PFASs) in aater samples by bamboo charcoal-based SPE, parabens in environmental water samples, benzotriazoles as environmental pollutants, organochlorine pesticide residues in various fruit juices and water samples and synthetic peptide purification are among the applications cited in this collection. All these outstanding contributions highlight the necessity of this analytical step, present the advantages and disadvantages of each method and focus on the green analytical chemistry guidelines that have to be fulfilled in current analytical practices.
