摘要

在农业领域,农药被大量使用,以保护我们的作物免受昆虫、杂草和疾病的侵害。只有一小部分农药能达到预定的目的,其余的农药会穿过土壤,污染地下水和地表水供应,破坏农田,最终危害作物,包括人类和其他生物。由于人们对使用电化学技术代替标准色谱法对分析物进行现场检测的兴趣日益浓厚,农药测量的替代方法最近受到了广泛的关注。在所有有机氯农药中,γ -林丹是有害的、有毒的、无处不在的环境污染物。在本文中,我们总结了伽马-林丹的不同检测方法,使用各种裸碳和表面修饰的玻璃碳和铅笔碳电极进行电化学技术,即循环、微分、方波伏安法和安培法。检测限分别为18.8 nM (GCE - aonp - pani - swcnt)、37000 nM (GCE)、38.1 nM (Bare HBPE)、21.3 nM (Nyl-MHBPE);回收率为103%。

Electrochemical Reduction and Voltammetric Sensing of Lindane at the Carbon (Glassy and Pencil) Electrodes
In the agricultural field, pesticides are used tremendously to shield our crops from insects, weeds, and diseases. Only a small percentage of pesticides employed reach their intended target, and the remainder passes through the soil, contaminating ground and surface-water supplies, damaging the crop fields, and ultimately harming the crop, including humans and other creatures. Alternative approaches for pesticide measurement have recently received a lot of attention, thanks to the growing interest in the on-site detection of analytes using electrochemical techniques that can replace standard chromatographic procedures. Among all organochlorine pesticides such as gamma-lindane are hazardous, toxic, and omnipresent contaminants in the environment. Here, in this review, we summarize the different ways of the gamma-lindane detection, performing the electrochemical techniques viz cyclic, differential, square wave voltammetry, and amperometry using various bare and surface-modified glassy carbon and pencil carbon electrodes. The analytical performances are reported as the limit of detection 18.8 nM (GCE–AONP–PANI–SWCNT), 37,000 nM (GCE), 38.1 nM (Bare HBPE), 21.3 nM (Nyl-MHBPE); percentage recovery is 103%.
