“…The application based on magnetic GO in the preparation of samples to adsorb trace analytes has also received increased attention over the past few years [97,[98][99][100]. In this study, we synthesized magnetic Fe3O4 graphene oxide (Fe3O4/GO) as an adsorbent for the extraction, pre-concentration and determination of three commonly used chemicals (bisphenol A, naproxen, and triclosan) frequently detected in wastewater.…”

Solid Phase Extraction is a method used for extraction, purification of compounds contained in complex matrices and purification of samples in the fields of industry, pharmacy, and toxicology analysis. This review represents the recent advances of solid phase extraction from different mode of separation which are the most commonly used in recent days such as molecular imprinting solid phase extraction (MISPE), magnetic solid phase extraction (MSPE) and matrix solid phase dispersion (MSPD). In this review, the applications of MISPE in the analysis of agrochemicals such as herbicides, fungicides and insecticides are summarized. This review also states preparation of various magnetic composites (MSPE) based on graphene and its application as adsorbents in pre concentrating natural mixes, organic macromolecules. Besides this, this review summarizes the application of MSPD in biological, food, and environmental samples, including both organic and inorganic analyte.

“…Nowadays, due to several advantages such as reducing matrix effects and interfering species, and preconcentration of the analyte, microextraction methods are widely used as sample preparation method for real samples such as biological and Pharmaceutical, water and wastewater, industrial and food samples [14][15][16][17]. Dispersive solid phase microexrtraction is a new, rapid and practical method for extraction of various analytes using a dispersing solid sorbent to separate then from the sample solution [18,19]. The main benefit of this method compared to traditional SPME is reducing the time of extraction and the amount of sorbent and also preventing from swelling and breakage of SPME fiber.…”

A simple and highly sensitive dispersive solid phase microextraction method coupled with flame atomic absorption spectrometry is proposed for preconcentration and determination of beryllium in real water and alloy samples employing cerium oxide nanoparticles as novel DSPME sorbent. This sorbent showed to be very effective for extraction of Be ion at the presence of interfering ions. Different parameters affecting the microextraction procedure such as nanoparticles amounts, pH, stirring and centrifuging times and the type and amount of desorption solvent were thoroughly studied and optimized. Under the optimized conditions, the calibration curve for Be was linear in the range of 0.05-25 µg L -1 with a correlation coefficient of 0.99. This method also shows low the relative standard deviation (RSD) and high preconcentration factor for determination of Be ion in real samples. The effects of different interfering ions on the Be determination were investigated and the method was successfully employed for its determination in well, tap and river water samples, and an alloy. The accuracy of method was also evaluated using a standard reference material.

“…Therefore, sample preparations such as extraction, cleanup and pre-concentration before instrumental analysis are mandatory. Solid-phase extraction (Zhang et al 2011;Sabermahani et al 2012;Iraji et al 2013;Afzali et al 2014;Kazemi et al 2015), cloud-point extraction (Manzoori et al 2007;Tavakoli et al 2008), co-precipitation (Messerschmidt et al 2000), and liquid-liquid extraction (LLE) (ElShahawi et al 2007;Vasilyeva et al 1975;Ohava et al 1995;Kolekar and Anuse 2001) are used for sample preparation purposes. LLE has been widely used for separation and pre-concentration of gold ions.…”

Ion-association dispersive liquid–liquid microextraction of ultra-trace amount of gold in water samples using Aliquat 336 prior to inductively coupled plasma atomic emission spectrometry determination

Background: Gold is a rare and noble metal with atomic number of 79. Several techniques including both spectrometric and electrochemical methods are widely used to determine gold level in real samples. As a result of low concentration of gold in environmental samples, sample preparations such as extraction, clean-up, and pre-concentration before instrumental analysis are mandatory. Thus, a pre-treatment method (dispersive liquid-liquid microextraction (DLLME)) for gold pre-concentration and inductively coupled plasma optical emission spectrometry (ICP-OES) determination is proposed. Methods: An extraction method employing DLLME and ICP-OES has been developed for rapid separation, pre-concentration, and determination of ultra-trace amount of Au (III). The extraction of the analyte was performed in the presence of a quaternary ammonium cation, N-methyl-N,N,N-trioctylammonium chloride, (Aliquat 336) as an extractant based on ion-association extraction system.
