Electrochemical determination of mangiferin using modified screen printed electrode

Abstract

In this research, the utilization of ZnFe 2 O 4 nanoparticles modified screen printed electrode (ZnFe 2 O 4 /SPE) was focused on as a sensor to determine mangiferin. The modified electrode performance was examined via the differential pulse and cyclic voltammetric methods. Mangiferin electrochemical behavior in phosphate solution of pH 7.0 was assessed by utilizing unmodified SPE and ZnFe 2 O 4 /SPE. Results indicated that ZnFe 2 O 4 /SPE electrochemical response to mangiferin was considerably advanced. Linear responses were exhibited by ZnFe 2 O 4 /SPE in mangiferin electrochemical oxidation within concentration range 0.1-600.0 μM. The ZnFe 2 O 4 /SPE sensor exhibited suitable response for mangiferin with 0.03 μM (S/N=3) detection limit. ZnFe 2 O 4 /SPE analytical application was tested with favorable results in determining mangiferin in real samples.
