The environmental emergence of unexpected contaminants has gained the attention of the scientific community. A broad spectrum antimicrobial compound named triclosan (TCS) was detected in the environment as an emerging contaminant. Owing to its inherent toxicity, we have proposed eco-friendly potentiometric liquid state sensors to be used for monitoring and quantifying TCS in environmental water samples. The proposed sensors have been optimized by modifying the inner filling solution using hydrophilic 2-hydroxypropyl β-cyclodextrin as a complexing agent to be capable of minimizing the trans-membrane ion flux and hence improving the selective and sensitive determination of TCS in environmental matrices with low LOD values. The obtained linear response of the optimized sensor was (1 × 10⁻⁹ to 1 × 10⁻⁵ M) compared to the control sensor (1 × 10⁻⁸ to 1 × 10⁻⁴ M). The obtained limit of detection (LOD) value was found to be 9.86 × 10⁻¹⁰ M compared to 9.78 × 10⁻⁹ M of the control sensor. The modification of the inner filling solution of the sensor with 2-hydroxypropyl β-cyclodextrin improves not only its sensitivity but also its response time to be only 5 seconds. The electrical performance of the proposed sensor was evaluated following IUPAC recommendations. Both the pH and temperature effects were studied and optimized. Two different greenness assessment tools, Analytical Eco-scale and Green Procedure Index, were adopted upon the evaluation of the proposed sensors' greenness.

使用环糊精修饰的环保型电化学传感器原位监测亚纳摩尔检测限以下环境水中的三氯生

意外污染物在环境中的出现引起了科学界的关注。在环境中检测到一种广谱的抗菌化合物三氯生（TCS）作为新出现的污染物。由于其固有的毒性，我们提出了环保型电位液体状态传感器，用于监测和定量环境水样品中的TCS。通过使用亲水性2-羟丙基β-环糊精作为络合剂来修饰内部填充溶液，从而优化了拟议的传感器，从而能够最小化跨膜离子通量，从而改善了低浓度环境基质中TCS的选择性和灵敏测定LOD值。优化传感器的线性响应为（1×10 ^-9至1×10^-5 M）与控制传感器（1×10 ^-8至1×10 ^-4 M）相比。发现所获得的检测极限（LOD）值为9.86×10 ^-10 M，而控制传感器为9.78×10 ^-9M。用2-羟丙基β-环糊精修饰传感器的内部填充溶液，不仅将其灵敏度提高，而且将响应时间缩短到仅5秒。根据IUPAC的建议评估了拟议传感器的电气性能。研究和优化了pH和温度的影响。在评估拟议传感器的绿色度时，采用了两种不同的绿色度评估工具，即分析生态规模和绿色程序指数。
