Abstract

Synthesis and characterization of the electrochemical properties of manganese ferrite nanoparticles (\ce {MnFe2O4}) from iron ore have been done. The aim of this research was to determine the potential of iron ore as a source for the manufacture of \ce {MnFe2O4} and to know electrochemical characterization. The precipitation method was used in this research. Iron ore samples were taken from Tanah Laut Regency, South Kalimantan, Indonesia. The sample of iron ore was purified first to synthesis MnFe2O4 nanoparticle. Manganese salt \ce {MnCl2} is used as a source of manganese. Characterization of samples use TEM and potentiostat. Glucose oxidase (GOD) is used as a sample to be given electrochemical properties of the sample. The GOD concentration used is 0.2; 0.4; 0.6; and 0.8 ppm. The range of \ce {MnFe2O4} nanoparticles was successfully made with sample diameters ranging from 1.5 to 12.5 nm. The current values ​​obtained on \ce {MnFe2O4} nanoparticles range from $0.226 - 0.322$ mA. The sensitivity of \ce {MnFe2O4} nanoparticles is around 0.16 mA/ppm. The higher the concentration used, the greater the current produced.
