Abstract

Objective: Uncomplicated, low-cost, highly discerning, and sensitive electrochemically active nanosensors have been synthesized using copper salt as a precursor, surfactants, and structural directing agents. These synthesized CuO Nanoparticles (NPs) were electroactive and EC treatments were also performed by modifying these NPs with graphite powder (CPE) to enhance the electrocatalytic activity, sensitivity.

Material and Method: The characterization of these fabricated nanosensors was done by cyclic voltammetry (CV), differential pulse voltammetry (DPV), field emission scanning electron microscopy (FESEM), powder X-ray diffraction (PXRD), transmission electron microscopy (TEM).

Result and Discussion: The EC behavior of Organophosphorus (OP) pesticides in the real samples was examined by these fabricated sensors. Parameters such as pH of solution scan rate of the experiment, accumulation time, and potential difference have been optimized in the experiment for trace determination of OP pesticides.

CuO VE GRAFİT TOZUNA DAYALI ELEKTROKİMYASAL NANOSENSÖR İMALATI VE GERÇEK NUMUNELERDE OP (ORGANOFOSFOR) PESTİSİTLERİNİN ESER MADDE ANALİZİ İÇİN UYGULAMASI

Abstract

Amaç: Karmaşık olmayan, düşükmaliyetli, son derece seçici ve hassas elektrokimyasal olarak aktif nanosensörler,bir öncü olarak bakır tuzu, yüzey aktif maddeler ve yapısal yönlendirme ajanları kullanılarak sentezlenmiştir. Sentezlenen bu CuO Nanopartiküller (NP'ler) elektroaktiftir ve elektro katalitik aktiviteyi ve hassasiyeti artırmak için grafit tozu (CPE) ile modifiye edilerek EC işlemleri de gerçekleştirilmiştir.

Gereç ve Yöntem: Bu fabrikasyon nano sensörlerin karakterizasyonu, dönüşümlü voltametri (CV), diferansiyel puls voltametri (DPV), alan emisyonu taramalı elektron mikroskobu (FESEM), toz X-ışınıkırınımı (PXRD) ve transmisyon elektron mikroskobu (TEM) ile yapılmıştır.

Sonuç ve Tartışma: Organofosforlu (OP) pestisitlerin gerçek numunelerdeki EC davranışı bu fabrikasyon sensörlerle incelenmiştir. OP pestisitlerinin eser madde tespiti için çözelti tarama hızının pH'ı, birikme süresi ve potansiyel fark gibi parametreler optimize edilmiştir.
