In this research, an environmental friendly, green and efficient sample preparation method using vortex-assisted microextraction based on a deep eutectic solvent (VAME-DES) followed by graphite furnace atomic absorption spectrometry (GFAAS) was developed for the preconcentration and determination of As(III)/As(V) and total inorganic arsenic in soil and vegetables irrigated with treated municipal wastewater from Tehran and Kermanshah, Iran. In the proposed method, a novel DES, characterized by it...

We report on the successful release-modulation of ceftriaxone (CEF) by an applied potential on a chitosan hydrogel-based composite. Here, the performance of chitosan (CHIT)-based composites were evaluated on glassy carbon electrode (GC), GC-ordered mesoporous carbons (OMCs) and Graphene (Gr), which offer attractive features such as good electronic conductivity and effectiveness in delivering electroactive surface area. Ceftriaxone was selected as an indicator of cephalosporins as a model drug. B...

Continuous sample drop flow-based microextraction (CSDF-ME) combined with graphite furnace atomic absorption spectrometry (GFAAS) has been developed as a high-performance preconcentration technique for the determination of cadmium in cosmetic samples. In this method, a few microliters of an organic solvent, e.g. 37.0 µL of carbon tetrachloride, is transferred to the bottom of a conical sample cup. Then, 10.0 mL of an aqueous solution added via a syringe needle becomes transformed into fine dropl...

Abstract The continuous sample drop flow microextraction (CSDFME) joined with the iridium-modified tube graphite furnace atomic absorption spectrometry (GFAAS) has been developed as a highly sensitive technique for the speciation of selenium in blood samples. In this method 32.0 μl carbon tetrachloride is transferred to the bottom of a conical sample cup. Then the 5.0 ml of aqueous solution transforms to fine droplets while passing through the organic solvent. At this stage, Se(IV)-APDC hydropho...

A simple, inexpensive, reliable, dispersive-solvent-free and environmentally friendly method based on continuous sample drop flow-microextraction (CSDF-ME) and high performance liquid–liquid chromatography-ultraviolet detection (HPLC-UV) was developed for the determination of triazine herbicides in fruit juice samples. In this method, a few microliters of organic solvent is transferred to the bottom of a conical test tube. Then, 5.0 mL of aqueous solution transforms to form fine droplets while p...

ABSTRACTThis study was designed to determine the ultra-trace amounts of lead (Pb) and cadmium (Cd) in various cereals (rice, wheat, barley, peas, beans, corn and lentil) obtained from the markets in Kermanshah city, West Iran. An efficient microextraction method was applied to separation and preconcentration of metal ions. This method is dispersive liquid–liquid microextraction based on solidification of floating organic drop, which overcomes the most important problems of other microextraction ...

A simple, inexpensive, reliable and environmentally friendly method based on ultrasound assisted extraction (UAE) combined with dispersive liquid-liquid microextraction with solidification of floating organic drop (DLLME-SFO) was developed for the simultaneous determination of four triazines in fruit and vegetable samples. Parameters affecting the extraction process were studied and optimized. Under the optimum conditions (sonication time: 15 min; extraction solvent: 30.0 μL 1-undecanol; dispers...

Human exposure to inorganic arsenic (iAs) via rice consumption is of increasing concern. In the present study, microwave-assisted dispersive liquid–liquid micro-extraction (MADLLME) and electrothermal atomic absorption spectrometry (ETAAS) were developed for the speciation of iAs in rice samples. After microwave-assisted digestion, the As(III) ion reacted with diethyldithiophosphoric acid (DDTP) to form an As–DDTP complex and was extracted at the same time. Some parameters affecting digestion, c...
