“…Recently, efforts have been made to use more affordable adsorbent in the adsorption of pesticides. Adsorbents that have been reported for fast adsorption of pesticides are organic porous polymers [4], cellulose acetate (CA) [18], silica particles [7], graphene oxide (GO) [19] and multi-walled carbon nanotubes [20]. CA has been widely investigated as a type of hybrid adsorbent as compared with the other materials and exhibits potential applications for pesticides adsorption.…”

“…At this point, the analytes started to react with hydroxide ions to form OPPs hydroxide (conjugated form) and started to be precipitated (ionized) [19]. Therefore, the opportunity of OPPs analytes to bind to the adsorbent surface is lessened [19]. Other than that, at this point, OPPs analytes undergo hydrolysis rather than adsorption [19].…”

Superhydrophilic graphene oxide/electrospun cellulose nanofibre (GO/CNF) was synthesized, characterized and successfully used in a solid-phase membrane tip adsorption (SPMTA) as an adsorbent towards a simultaneous analysis of polar organophosphorus pesticides (OPPs) in several food and water samples. Separation, determination and quantification were achieved prior to ultra-performance liquid chromatography coupled with ultraviolet detector. The influence of several parameters such as sample pH, adsorption time, adsorbent dosage and initial concentration were investigated. SPMTA was linear in the range of 0.05 and 10 mg l −1 under the optimum adsorption conditions (sample pH 12; 5 mg of adsorbent dosage; 15 min of adsorption time) for methyl parathion, ethoprophos, sulfotepp and chlorpyrifos with excellent correlation coefficients of 0.994–0.999. Acceptable precision (RSDs) as achieved for intraday (0.06–5.44%, n = 3) and interday (0.17–7.76%, n = 3) analyses. Low limits of detection (0.01–0.05 mg l −1 ) and satisfactory consistency in adsorption (71.14–99.95%) were obtained for the spiked OPPs from Sungai Pahang, Tasik Cheras, cabbages and rice samples. The adsorption data were well followed the second-order kinetic model and fits the Freundlich adsorption model. The newly synthesized GO/CNF showed a great adsorbent potential for OPPs analysis.

A novel adsorbent made of polydopamine-functionalized magnetic graphene and carbon nanotubes hybrid nanocomposite was synthesized and applied to determine 16 priority polycyclic aromatic hydrocarbons by magnetic solid phase extraction in water samples. FTIR spectroscopy, transmission electron microscopy, scanning electron microscopy, and Raman spectroscopy consistently indicate that the synthesized adsorbents are made of core-shell nanoparticles well dispersed on the surface of graphene and carbon nanotubes. The major factors affecting the extraction efficiency, including the pH value of samples, the amount of adsorbent, adsorption time and desorption time, type and volume of desorption solvent, were systematically optimized. Under the optimum extraction conditions, a linear response was obtained for polycyclic aromatic hydrocarbons between concentrations of 10 and 500 ng/L with the correlation coefficients ranging from 0.9958 to 0.9989, and the limits of detection (S/N = 3) were between 0.1 and 3.0 ng/L. Satisfactory results were also obtained when applying these magnetic graphene/carbon nanotubes/polydopamine hybrid nanocomposites to detect polycyclic aromatic hydrocarbons in several environmental aqueous samples.

“…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. [15][16][17] Besides, own to the large specific surface area of magnetic nanoparticles, it results in relatively higher extraction capacity and detection sensitivity. 18,19 The iron oxides magnetite (Fe3O4) are by far the most commonly used magnetic materials in sample preparation because of the simple procedures of fabrication, their superparamagnetic character and low toxicity.…”

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%.
