Abstract
This manuscript reveals the synthesis of ferric doped nickel oxide (Fe–NiO) nanoparticle via a co-precipitation method and is depicted by XRD, SEM and EDS analysis. It is utilized as modifier at bare CPE with analysis of ascorbic acid (AA). AA (vitamin-C) found in citrus fruits and vegetables, it is acts as essential nutrients involved in tissue repair, making of collagen and enzymatic constructions of certain neuro transmitters. The Fe–NiO/MCPE brings the excellent selectivity and sensitivity towards AA in existence of Paracetamol (PA) by using cyclic voltammetry and differential pulse voltammetry. The experimental parameters like pH, sweep rate and concentration studied at 0.2 M PBS solution for the investigation of AA and PA. The Fe–NiO/MCPE is used for the illustration of AA and PA, The limit of detection for both AA and PA is 4.47 μM and 1.84 μM respectively. The prepared sensor can be used for the resolve of AA in real sample investigation.
