Abstract

A dispersive solid phase extraction method using new magnetic nanoparticles based on nickel ferrite was introduced for the extraction of six triazole pesticides (penconazole, hexaconazole, tebuconazole, diniconazole, triadimefon, and difenoconazole) from water samples before liquid chromatography-tandem mass spectrometry analyses. Initially, a new deep eutectic solvent was synthesized with 1,2,4-triazole and n-octanol for surface modification of the nanoparticles easily achieved through microwave radiation. The nanoparticles morphology, magnetic properties, adsorption capacity, isotherms, and crystalline patterns of the sorbent were examined. The capability of the sorbent was evaluated by extracting the target pesticides from water samples showing significant differences in adsorption capacity and efficiency between the modified and non-modified nanoparticles. High extraction recoveries (68-86 %) were achieved for the analytes using small amounts of the sorbent with low limits of detection (0.03-0.08 ng mL^-1) and quantification (0.13-0.29 ng mL^-1), a wide linear range (0.29-250 ng mL^-1), and acceptable precision (relative standard deviations ≤6.9 %).

基于 1,2,4-三唑的深共晶溶剂改性镍铁氧体纳米粒子的合成及其在 LC-MS/MS 分析前分散固相萃取三唑类农药中的应用。

在液相色谱-串联质谱分析之前，介绍了一种使用基于镍铁氧体的新型磁性纳米粒子的分散固相萃取方法，用于萃取水样中的六种三唑类农药（戊唑醇、己唑醇、戊唑醇、地尼环唑、三唑酮和苯醚甲环唑）。首先，用 1,2,4-三唑和正辛醇合成了一种新的深共晶溶剂，以便通过微波辐射轻松实现纳米粒子的表面改性。研究了吸附剂的纳米颗粒形态、磁性能、吸附能力、等温线和结晶形态。通过从水样中萃取目标农药对吸附剂的能力进行了评估，结果表明改性和非改性纳米粒子的吸附能力和效率存在显著差异。使用少量吸附剂就能获得很高的萃取回收率（68-86%），检出限（0.03-0.08 ng mL-1）和定量限（0.13-0.29 ng mL-1）都很低，线性范围很宽（0.29-250 ng mL-1），精度也可以接受（相对标准偏差≤6.9%）。

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.
