ZnO polythiophene SBA-15 nanoparticles as a solid-phase microextraction fiber for fast determination essential oils of Matricaria chamomilla
The objective of this study is determination the volatile compounds of Matricaria chamomilla of an inorganic–organic hybrid material based on ZnO nanoparticles anchored to a composite made from polythiophene and hexagonally ordered silica (ZnO/PT/SBA-15) as a solid-phase fiber microextraction (SPME). Microextraction techniques with nanoparticles ZnO/PT/SBA-15 resulted in a more efficient analyt...
متن کاملOrdered nanoporous carbon (CMK-3) coated fiber for solid-phase microextraction of benzene and chlorobenzenes in water samples
Nanoporous carbons (CMK-3) were prepared and have been used as a fiber coating for headspace solid phase microextraction (HS-SPME). The prepared materials were characterized by Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) and N2 adsorption/desorption isotherms. The efficiency of the fiber was evaluated using a gas chromatography (GC) system for the extraction of benzene (B) and c...
متن کاملHCl- Etched Steel Fiber for Determination of Phthalates in Water Samples by Solid-Phase Microextraction
In the present work, a stainless steel wire was etched by hydrochloric acid during a chemical etching process. The obtained black layer on the surface of the fiber was used as sorbent for extraction of trace amount of phthalates in the aqueous samples by solid phase microextraction. New fiber efficiency was investigated using a home-made solid-phase microextraction (SPME) device and gas chr...
متن کاملQualitative and quantitative changes in the essential oil of sage (Salvia hydrangea DC exBenth.) as affected by different drying methods
Background & Aim: Salvia hydrangea is one of the medicinal plants belonging to Lamiaceae family. Medicinal plants can be marketed as fresh or dried products; however aromatic plants are often dried before extraction to reduce moisture content. The aim of this study was to evaluate the impact of different drying methods on qualitative and quantitative changes in essenti...
