<p>Calcium Zirconium Titanium Oxide Multiwalled Carbon nanotubes nanocomposites was synthesized by solution combustion method. A carbon paste electrode was used to create a Voltammetric resolution for Copper Zirconium Titanium Oxide Multiwalled Carbon nanotubes nanocomposites. The electrochemical oxidation was carried out in 0.2&#xa0;M Phosphate buffer solution at scan rate 0.05Vs⁻¹. Electrochemical investigation of L-Dopa, Uric Acid and Tyrosine was studied by scan rate varation by this it has confirmed all analytes shows diffusion controlled process, by varying the concentration of the analytes limit of detection and quantification are obtained and by pH studies number of protons and electron are obtained. Simultaneous study was carried out for L-Dopa, Uric Acid and L-Tyrosine. The CZTO MWCNT nanocomposites MCPE was used for investigation of UA in real sample.</p>
