A sensitive voltammetric sensor based on silver nanoparticles/carbon nitride nanotubes@graphene quantum dots/a novel organic liquid: determination of triclosan in wastewater

摘要

A new sensor approach based on silver nanoparticles (AgNPs)/carbon nitride nanotubes (C$_3$N$_4$NTs)@graphene quantum dots (GQDs)/5-nitro-2-(3-hydroxy-4-methoxybenzylidenamino)-thiazole (ILs) was presented fortriclosan (TCS) detection in wastewater samples. X-ray diffraction method, scanning electron microscope, electrochemical impedance spectroscopy, transmission electron microscope and cyclic voltammetry methods were used for all nanomaterialsa?? characterizations. The linearity range and the detection limit (LOD) were found as $1.0 imes 10^{-11}$ to $1.0 imes 10^{-8}$ M and $2.0 imes 10^{-12}$ M, respectively. The nanocomposite-modified electrode was used for wastewater sample analysis in the presence of different agents.
