Abstract
This work describes the synthesis of tetra amino Zinc(II)metallophthalocyanine (Zn(II)TAPc) the synthesized molecules were characterized by spectral analysis are FT-IR, UV-Visible, TGA, XRD and electrochemical characterization. The electrochemical oxidation of dopamine (DA), ascorbic acid (AA) and uric acid (UA) was studied on MWCNT-Zn(II)TAPc/GCE due to its excellent electron transferring ability than the bare glassy carbon electrode and Zn(II)TAPc/GCE since there is tuned the surface area of glassy carbon electrode decorated with multiwalled carbon nano tubes and Zn(II)Pc (MWCNT-Zn(II)TAPc). Therefore electrochemical sensing of micromoler concentration of dopamine, ascorbic acid and uric acid has done on MWCNT-Zn(II)TAPc/GCE the linear range of (CV 0.02 – 50 μmol L−1 ), lower detection limit of (CV 0.0066 μmol L−1 ) and sensitivity of (CV 56.03 μAμM−1 cm−2 ), similarly AA, UA are discussed in the below table. The fabricated sensor shows good electrocatalytic activity than the modified electrode with Zn(II)Pc alone towards oxidation of bio-molecule. The MWCNT-Zn(II)TAPc/GCE shows good repeatability, stability and aunty leaching properties. The MWCNT-Zn(II)TAPc/GCE is highly stable, sensitive and reproducible for the micromolar detection of DA, AA and UA.
