Green analytical chemistry principles aim to minimize the negative impact of procedures in environment, which can be considered both at close (to ensure safety analysts) and global conserve our natural resources) levels. These suggest, among other guidelines, reduction/minimization sample treatment use renewable sources when possible. The first aspect is largely fulfilled by microextraction, greenest techniques. second consideration attainable if products are used as raw materials for...
This article describes a method for the modification of paper with single-wall carbon nanohorns (SWCNHs) to form stable suprastructures. The SWCNHs dahlia-like aggregates in solution that are then self-assembled into superior structures if solvent is evaporated. Dipping sections dispersion leads formation thin film can be used microextraction purposes. coated easily handled simple pipette tip, paving way disposable extraction units. As proof concept, antidepressants from urine and their...
A new procedure for the functionalization of melamine sponge (MeS) with urea-formaldehyde (UF) co-oligomers is put forward. The differs from typical synthesis UF co-polymer, as it employs a base-catalyzed condensation step at certain concentrations urea and formaldehyde. produced melamine-urea-formaldehyde (MUF) cubes are hydrophobic, despite presence hydrophilic groups in oligomers. MUF developed herein used sorbent solid-phase extraction 10 analytes, 6 different classes (i.e.,...
The pollution of environmental resources is an issue social concern worldwide. Chemistry essential for the design decontamination strategies and analytical approaches to detect monitor contamination. Sorptive materials are usually required in both green synthesis should be used minimize their own impact. Carbon fibers (CFs) obtained by pyrolysis natural cellulose-rich fulfill these requirements. In this article, thirty CFs under different conditions chemically characterized sorption ability...
Mesofluidic lab-on-a-valve (LOV) platforms have been proven suitable to accommodate automatic micro-solid-phase extraction (μSPE) approaches with on-chip handling of micrometer-bead materials in a fully disposable mode prevent sample cross-contamination and pressure-drop effects. The efficiency the process notably depends upon sorptive capacity material because sorbent mass is usually down 10 mg LOV devices. Nanomaterials, capitalizing their enhanced surface-to-volume ratio diversity...
Background: In this article, carbon coated titanium dioxide nanotubes (TiO2-NT@C) are employed for the determination of 5-hydroxyindole-3-acetic acid in urine by LC–MS/MS. Results: All variables involved extraction have been studied and optimized depth. The method has analytically characterized on basis its linearity, accuracy, sensitivity precision. LOD is 155.8 μg/l while repeatability reproducibility, expressed as RSD, better than 5.42 5.25%, respectively. obtained relative recovery 115%....
