Abstract

An electrochemical sensor for the sensitive and selective measurement of Uric acid in the presence of Guanine is created using bismuth ferrite Multiwalled carbon nanotube (MWCNT) nanocomposites modified carbon paste electrode (MCPE). The simple combustion approach was used to synthesize the bismuth ferrite MWCNT nanocomposites. Bismuth ferrite MWCNT nanocomposite structural morphology and characterization were investigated through the use of EDX, FT-IR, SEM, and powder XRD. At very low concentrations, bismuth ferrite MWCNT nanocomposites had an amazing synergistic effect on Uric acid (UA) electrochemical sensing. Under ideal circumstances, the bismuth ferrite MWCNT nanocomposites MCPE demonstrated good linear properties for the quantitative analysis of UA and GU with a limit of detection 1.56 µM and 0.085 µM respectively, and simultaneous study of UA and GU is carried out by cyclic voltammetry and differential pulse voltammetry. The bismuth ferrite MWCNT nanocomposites MCPE was used for analysis of UA and GU in the real samples.
