“…In addition, the exclusion of a disperser solvent, which is consumed in fairly larger volumes compared to an extraction solvent, will make the extraction procedure greener. Ultra-sonication (28), vortex (29), and air agitating (27) of the sample solution are proposed alternatives of the disperser solvent. Although these techniques have been successful, being timeconsuming is their main drawback, particularly regarding the case of the air-agitated method.…”

Background: Organophosphates (OPPs) are toxic chemicals that can cause serious health problems through poisoning water and food. Objectives: A very simple and fast disperser-less liquid microextraction strategy before chromatographic detection was designed for the analysis of organophosphates in various water solutions. Methods: A 60 µL aliquot of chloroform, as extraction solvent (without using disperser), was introduced into the sample solution by rapid injection, and the sedimented organic phase was analyzed to assay some organophosphates. Results: Analytical characteristics, including limits of detection (0.0003 - 0.001 µg.L-1), linear dynamic ranges (0.001 - 100 µg.L-1), relative standard deviations (2.5 - 10), enrichment factors (up to 238), and extraction recoveries (84% - 108%), indicated the high efficacy of the developed method for analyzing the target analytes. Conclusions: The proposed procedure was effectively used for the analysis of the OPPs in real tap water, river water, and fruit juice samples. In the present study, the examined analytes were in the range of 0.07 - 1.56 µg.L-1.

“…[45][46][47] Among the various techniques of liquid-liquid microextraction, the vortex-assisted turns out to be promising. 48,49 The vortexassisted liquid-liquid microextraction of the product of the redox reaction (I 3 À ) of dichromate with iodides in the form of ion association pair with cationic dye was not previously used for the indirect determination of chromium(VI). In this study, we have used the vortex-assisted liquid-liquid microextraction procedure to indirectly determine Cr(VI) by spectrophotometry.…”
