“…Also SPE can be laborious, time-consuming and involve increased consumption of organic solvents. 17,22 An alternative is the d-SPE method, commonly applied as clean-up step in the QuEChERS (quick, easy, cheap, effective, rugged and safe) approach, 23 when elution step is not required. 24 Dyes are often adsorbed in the sorbent, thus elution is an indispensable condition.…”

A simple, fast and efficient method was developed for determination of six synthetic dyes (Tartrazine, Sunset Yellow, Amaranth, Ponceau 4R, Indigo Carmine and Brilliant Blue) in sports drinks using dispersive solid-phase extraction (d-SPE) with the polymeric sorbent Oasis ® HLB. Sample preparation using d-SPE permitted to simplify the procedure and use less sorbent in comparison with SPE. The use of a syringe for the elution step make this easier and avoid the use of a manifold. High performance liquid chromatography with UV-Vis detection was employed for quantification. Recovery results, evaluated at 0.5; 1.0 and 1.5 mg L -1 , were between 76 and 108% with relative standard deviation < 18%. The method limit of quantification was 0.5 mg L -1 . The developed method was applied to the analysis of commercial sports drinks and the results indicated that all studied samples presented dye levels in conformity with the Brazilian legislation. Keywords: food additives, beverages, d-SPE, sample preparation, liquid chromatography IntroductionSports drinks are specially formulated for people who are undertaking physical activity, being mainly composed by carbohydrates, electrolytes and vitamins.1 Additives such as flavors, stabilizers and dyes are commonly used in sports drinks to prevent for spoilage and improve their consumer characteristics and appearance. Nevertheless, this addition must not change the properties of the final product.2 Synthetic dyes are a very important class of food additives.3 Besides the lower cost of production in relation to dyes of natural origin, synthetic colorants have several advantages such as high stability to light, oxygen and pH, color uniformity and low microbiological contamination. 4 However, some of these compounds pose adverse health effects (allergy, asthma, hyperactivity, thyroid tumors, etc.), especially when consumed in excess. Thus, their use is strictly controlled around the world. 5 The list of allowable kinds and concentrations of synthetic dyes is different in each country or region, mainly due to differing opinions regarding the safety of these substances and due to a greater or lesser consumption of artificially colored products.6 In Brazil, the maximum limit of colorants in foods including sports drinks is established by the National Agency of Sanitary Surveillance (ANVISA), based on international regulations. 7In general, high-performance liquid chromatography (HPLC) methods with ultraviolet-visible (UV-Vis), diode-array (DAD) and mass spectrometry detection have been employed for synthetic dyes analysis to ensure food safety. Despite the wide variety of cartridges commercially available for preparation/purification of foods matrices, SPE steps can be laborious and often requires vacuum or positive-pressure manifold to perform the extraction. 17,18 Other methods based on the traditional SPE, such as dispersive solid-phase extraction (d-SPE) and magnetic solid-phase extraction (M-SPE), are considered powerful techniques specially for clean-up of food extracts. 8 However, ...

“…Here, solid phase extraction (SPE) is the most common method for the isolation and enrichment of analytes. 4,5 There are a few methods describing the use of SPE before pentamidine determination employing mercantile products. 6,7 However, their applicability is low due to the insufficient selectivity of commercial sorbents and analytes in the complex sample.…”

The selective response of a templated polymer for the cationic drug pentamidine: implications from molecular simulations and experimental data

In this paper, we present an analysis of the surface modifications responsible for the selectivity of a new imprinted sorbent produced for the isolation of pentamidine cations. We examined the polymers formed from acrylic acid as the monomer, ethylene glycol dimethacrylate as the cross-linker and 4-methoxybenzamidine as the template. A molecular simulation showed the creation of the complex surface system joined with the protonation of the template molecule in a prepolymerization complex.Polymer cavity models enabled the adsorption process to be theoretically simulated, and the binding energies of the structurally related analytes were used as a measure of sorbent selectivity. An applicative analytical scheme for the determination of pentamidine in human urine was used to prove the utility of the templated polymer matrix. The analytical strategy involved separating the pentamidine through a molecularly imprinted solid phase extraction process and detecting it using high-performance liquid chromatography coupled with ultra-violet spectrophotometry. The experimental results demonstrated a good agreement with the theoretical evaluations.

“…Solid-phase extraction (SPE) is one of the established and popular methods for sample enrichment due to its high extraction efficiency. [11][12][13] However, it still has some drawbacks such as time-consuming due to the tedious operation procedures, relatively expensive of consumption, and sometimes limited by the sample volume. 14 To deal with these drawbacks, magnetic solid-phase extraction (MSPE) has attracted much attention since the sorbent can be easily separated from the sample solution using an external magnetic field without the need of additional centrifugation or filtration.…”

A novel magnetic absorbent based on Fe3O4 hollow nanospheres was developed for polycyclic aromatic hydrocarbons (PAHs) extraction. Fe3O4 hollow nanospheres were prepared by a one-pot facile solvothermal method and its structural properties were characterized by scanning electron microscope (SEM) and analyzer transmission electron microscopy (TEM). It was the first time to use hollow nanospheres which possess high special surface area for magnetic solid-phase extraction (MSPE). The extraction condition of Fe3O4 hollow nanospheres and its performance for PAHs was systematically investigated. Besides, its extraction performance also compared with bare Fe3O4 nanoparticles. The results indicated the structure with hollow and spherical Fe3O4 perform better enrichment ability than that with solid and amorphous ones. The developed MSPE coupled with HPLC method shows good linearity (0.1 -5 ng/mL) and low detection limits (2.5 -10 pg/mL) for six PAHs. It also has been executed for the analysis of environmental samples, with recoveries in the range of 84.6 -97.8%.
