Ionic liquids (ILs) are important materials used in several fields due to their unique thermophysical, electrochemical, and green properties. While ILs are used alone in various sensor and biosensor applications, their use with nanostructures is becoming very popular in electrochemical sensors. The most significant applications of ILs are the stabilization of nanoparticles during the synthesis and forming of catalytically induced hybrid composite structures due to their wide potential window and great conductivity. Thanks to these unique features, ILs-based materials are used as modification materials in electrochemical sensors in order to acquire enhanced sensor performance and higher sensitivity. Analysis of environmental samples is not only very important due to the increasing environmental pollution and health risk issues but also tedious because of the complex media containing many compounds simultaneously. Therefore, modified electrochemical sensors are a very advantageous option to meet the need for sensors with high sensitivity, low limit of detection (LOD) values, low cost, and easy application for the analysis of environmental samples. This review study overviews the latest applications of ILs-based materials modified electrochemical sensors for determining environmental contaminants such as drug residues, pesticides, heavy metals, etc., in related samples covering the years between 2015 and 2022.

离子液体 (IL) 因其独特的热物理、电化学和绿色特性而成为多个领域中使用的重要材料。虽然 IL 单独用于各种传感器和生物传感器应用，但它们与纳米结构的使用在电化学传感器中变得非常流行。ILs 最重要的应用是在合成和形成催化诱导的杂化复合结构过程中稳定纳米粒子，因为它们具有宽电位窗口和高导电性。由于这些独特的特性，基于离子液体的材料被用作电化学传感器中的改性材料，以获得增强的传感器性能和更高的灵敏度。由于日益严重的环境污染和健康风险问题，环境样品的分析不仅非常重要，而且由于同时包含许多化合物的复杂介质而变得乏味。因此，改进的电化学传感器是一种非常有利的选择，可以满足传感器对具有高灵敏度、低检测限 (LOD) 值、低成本和易于应用的环境样品分析的需求。本综述研究概述了基于 ILs 的材料改性电化学传感器在 2015 年至 2022 年间相关样品中测定药物残留、农药、重金属等环境污染物的最新应用。改进的电化学传感器是一种非常有利的选择，可以满足对具有高灵敏度、低检测限 (LOD) 值、低成本和易于应用的环境样品分析的传感器的需求。本综述研究概述了基于 ILs 的材料改性电化学传感器在 2015 年至 2022 年间相关样品中测定药物残留、农药、重金属等环境污染物的最新应用。改进的电化学传感器是一种非常有利的选择，可以满足对具有高灵敏度、低检测限 (LOD) 值、低成本和易于应用的环境样品分析的传感器的需求。本综述研究概述了基于 ILs 的材料改性电化学传感器在 2015 年至 2022 年间相关样品中测定药物残留、农药、重金属等环境污染物的最新应用。
