Abstract
A simple and efficient effervescence-assisted salting-out assisted liquid-liquid extraction (EA-SALLE) method was developed for the rapid extraction of pyrethroid insecticides in fruit juices and herbal extracts. By integrating effervescence extraction with SALLE, the extraction and phase separation processes were conducted simultaneously, significantly simplifying the experimental procedure and reducing the extraction time to just 3 min. Key factors influencing the method's efficiency were systematically optimized. Combined with gas chromatography with an electron capture detector, enabled the determination of nine pyrethroid insecticides, demonstrating excellent linearity (R2 > 0.99), low limits of detection (0.03-0.17 ng/mL), satisfactory accuracy (recoveries ranging from 83.0 % to 107.9 %), and good precision (RSD < 9.1 %). The proposed EA-SALLE method offers a simple, efficient, and cost-effective sample preparation technique. It is characterized by ease of operation, short extraction time, and high sensitivity, providing an effective tool for the monitoring and assessment of pesticide residues in complex samples.
期刊介绍：
Talanta provides a forum for the publication of original research papers, short communications, and critical reviews in all branches of pure and applied analytical chemistry. Papers are evaluated based on established guidelines, including the fundamental nature of the study, scientific novelty, substantial improvement or advantage over existing technology or methods, and demonstrated analytical applicability. Original research papers on fundamental studies, and on novel sensor and instrumentation developments, are encouraged. Novel or improved applications in areas such as clinical and biological chemistry, environmental analysis, geochemistry, materials science and engineering, and analytical platforms for omics development are welcome.
Analytical performance of methods should be determined, including interference and matrix effects, and methods should be validated by comparison with a standard method, or analysis of a certified reference material. Simple spiking recoveries may not be sufficient. The developed method should especially comprise information on selectivity, sensitivity, detection limits, accuracy, and reliability. However, applying official validation or robustness studies to a routine method or technique does not necessarily constitute novelty. Proper statistical treatment of the data should be provided. Relevant literature should be cited, including related publications by the authors, and authors should discuss how their proposed methodology compares with previously reported methods.
