Determination of 4-nitrophenol using MoO3 loaded glassy carbon electrode via electrochemical sensing approach

In order to raise possible ways of MoO3 synthesis and improve its existing applications, nanomaterial was successfully synthesized through the solvo-hydrothermal route by utilizing a mixture ionic liquid (1-butyl-3-methylimidazolium bromide) as solvent, water co-solvent in 1:1 ratio. The morphology structural parameters IL-as­sisted product were examined X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM). Additionally, surface wettability particle size distribution inspected using contact angle dynamic light scattering (DLS) analysis. Glassy carbon electrode (GCE) then modified IL-assisted MoO3. formed IL-MoO3/GCE employed an electro­chemical sensor for determination 4-nitrophenol (4-NP), which is very toxic important pollutant. redox behavior 4-NP at investigated cyclic voltammetry (CV) differential pulse (DPV) techniques. Limits detection (LOD) limits quantification (LOQ) determined from CV found be 6.76 22.5 mM, while DPV recordings, 5.41 18.0 mM are found. obtained results clearly reveal application selective sensitive sensing 4-NP. decorated river real samples.
