Recent Advances in Extraction and Stirring Integrated Techniques
The extraction yield of a microextraction technique depends on thermodynamic and kinetics factors. Both of these factors have been the focus of intensive research in the last few years. The extraction yield can be increased ...
Evaluación de un nuevo composite de nanopartículas magnéticas y nylon‐6 como sorbente en técnicas de microextracción en fase sólida dispersiva
(Sociedad Española de Química Analítica, 2015)
Silica nanoparticles–nylon 6 composites: synthesis, characterization and potential use as sorbent
(Royal Society of Chemistry, 2017)
Composite materials based on the combination of nanoparticles (NPs) and polymers have attracted much attention in recent years thanks to their positive characteristics. In this article an easy, cheap and green procedure ...
Carbon Nanohorn Suprastructures on a Paper Support as a Sorptive Phase
This article describes a method for the modification of paper with single-wall carbon nanohorns (SWCNHs) to form stable suprastructures. The SWCNHs form stable dahlia-like aggregates in solution that are then self-assembled ...
Tunable Polarity Carbon Fibers, a Holistic Approach to Environmental Protection
The pollution of environmental resources is an issue of social concern worldwide. Chemistry is essential for the design of decontamination strategies and analytical approaches to detect and monitor the contamination. ...
Melamine Sponge Functionalized with Urea-Formaldehyde Co-Oligomers as a Sorbent for the Solid-Phase Extraction of Hydrophobic Analytes
A new procedure for the functionalization ofmelamine sponge (MeS) with urea-formaldehyde (UF) co-oligomers is put forward. The procedure differs from the typical synthesis of the UF co-polymer, as it employs a base-catalyzed ...
Magnetic Polyamide Nanocomposites for the Microextraction of Benzophenones from Water Samples
In this article, the influence of the monomers on the extraction efficiency and the effect of the addition of surfactants during the synthesis have also been considered. The sorption capacity of the resulting nanocomposites ...
Determination of the Three Main Components of the Grapevine Moth Pest Pheromone in Grape-Related Samples by Headspace-Gas Chromatography-Mass Spectrometry
The grapevine moth (Lobesia botrana) is the most significant pest of viticulture. This article reports the development of an analytical method that allows the instrumental determination of the three main pheromone components ...
Returning to Nature for the Design of Sorptive Phases in Solid-Phase Microextraction
Green analytical chemistry principles aim to minimize the negative impact of analytical procedures in the environment, which can be considered both at close (to ensure the safety of the analysts) and global (to conserve ...
