Sustainable Sorbents: Oil Palm Empty Fruit Bunch-Derived Activated Carbon-Alginate Beads for Organochlorine Pesticides Extraction in Water Samples
Year: 2024
Type: article
Abstract: Pesticide residues in environmental water necessitate the urgent development of rapid and accurate determination methods for effectively monitoring and managing these contaminants.In response, micro-solid phase extraction (μ-SPE) using oil palm empty fruit bunch derived activated carbon-alginate beads (Alg-EFBAC-beads) was developed as a sample preparation method for extracting three organochlorine pesticides (OCPs) in water samples before gas chromatography-mass spectrometry (GC-MS) analysis.Essential parameters, including extraction time, desorption solvent, desorption time, and sorbent mass, were optimized using one variable at a time approach.Under the optimized conditions, the method showed good linearity (R 2 > 0.9777) in the concentration ranges of 1-10, 0.1-1.0, and 0.2-1.4mg/L for heptachlor, aldrin, and dieldrin, respectively.The applicability of the method was demonstrated through the analysis of selected pesticides in agricultural paddy water, with average recoveries ranging from 85 to 95%.The limits of detection (LOD) were between 0.04 and 0.29 mg/L.The greenness of the method was evaluated using the Analytical GREEnness Metric Approach (AGREE), demonstrating its viability as a sustainable solution for environmental monitoring and analysis of organochlorine pesticides in aqueous environments.
