“…In MEPS, like SPE, many sorbents can be used for the preconcentration and selective separation of the target compounds from different matrixes. Many materials such as polyaniline nanowire network and polydiphenylamine nanocomposite have been used as the sorbent in MEPS for extraction of OPPs . Among natural materials, diatomite or perlite is used as the sorbent for many applications.…”

“…In our previous work , for the first time, the natural nanodiatomite was applied as a nanosorbent in the MEPS technique for the preconcentration and determination of organochlorine pesticides in aqueous solutions at trace levels. Due to the extensive rice cultivation in the north of Iran, use of diazinon and other phosphorus pesticides is abundant against insects.…”

A rapid, low-cost, and simple method is proposed based on a miniaturized solid-phase extraction named microextraction in packed syringe coupled with gas chromatography and mass spectrometry for the preconcentration and determination of some organophosphorous pesticides including diazinon, ethion, and malathion. For the first time, natural nanoperlite is used as a safe sorbent. Based on this technique, the analytes are adsorbed on the solid phase and then eluted by a desorbing solvent. The influence of some important parameters such as the solution pH, type, and volume of the organic desorption solvent on the microextraction efficiency of the selected pesticide technique is investigated. The proposed method showed a good linearity in the range of 1.0-35.0 μg/L for ethion and 0.4-30.0 μg/L for both diazinon and malathion. The limits of detection in the range of 0.1-0.38 μg/L were obtained using the selected ion-monitoring mode of the mass spectrometer. The reproducibility of the method was found to be in the range of 2.8-8.9% for the studied pesticides. To evaluate the matrix effect, the developed method is also applied to the preconcentration and determination of the selected pesticides in real water samples.

“…Upon considering the impact of analytical procedures to the environment, sample preparation was found to be the most challenging step regarding the green parameters of a method. Solid-phase extraction was commonly used in the extraction of organic [2][3][4][5][6] and inorganic [7][8][9] contaminants from aqueous samples. It is also considered to be the main source of laboratory chemical waste.…”

This study deals with the application of different monoterpenes as relatively green bio-based solvents for low densitydispersive liquid-liquid microextraction (LD-DLLME) of different non-steroidal anti-inflammatory drugs (NSAIDs) from aqueous samples in comparison with conventional halogenated solvents. Results indicated that D-limonene could extract the hydrophobic compounds with higher %recovery compared with other bio-based and halogenated solvents. The LD-DLLME procedure was optimized by applying one-factor-at-a-time (OFAT) followed by central composite face-centered design (CCF) of the response surface methodology (RSM). Under the optimal conditions, the method exhibited good linearity with r ≥ 0.9950 with low LOD as well as LOQ levels in the range of 0.11 to 0.81 and 0.36 to 2.69 ng/mL, respectively. The method was efficiently applied to a variety of real aqueous samples. Finally, the green aspect of our procedure was compared with some reported methods using two green metric tools.
