Supramolecular Solvent-Based Microextraction of Propachlor and Prometryn Herbicides in Soil Samples Prior to Liquid Chromatographic Analysis
Journal Title: Cumhuriyet Science journal - Year 2018, Vol 39, Issue 4
Abstract
Supramolecular solvents (SUPRASs) are the nano-structured liquids generated from amphiphiles through a self-assembly process, and constitute an alternative to molecular organic solvents with becoming more environmentally friendly in sample preparation step. In this study, a SUPRAS-based analytical method has been proposed for the microextraction of propachlor and prometryn herbicides in soil samples. The method involved the vortex mixing of the 300 mg of soil sample with 300 µL of SUPRAS for 8 min, subsequent centrifugation for the phase separation, and direct analysis of the SUPRAS phase by liquid chromatography with ultraviolet detection. Under optimal extraction conditions, the extraction recoveries for the herbicides ranged from 81 to 87 %. The method detection limits for propachlor and prometryn were 0.07 and 0.01 μg/g, respectively. Relative standard deviations obtained for the herbicides were less than 8.8 % and 12.1 % for intra-day and inter-day precisions, respectively. The microextraction of related herbicides from soil samples collected from the Zonguldak region was carried out efficiently. The recoveries obtained from spiked soil samples ranged from 80 to 108 %.
