Abstract

In this research, zero-valent iron (ZVI) was synthesized from kepok banana peels extracts as reducing agent. The fourier transform infrared spectrum showed a clear peak at a wavenumber of 600 cm-1 that could be assigned to Fe-O bond. XRD measurement results prove that ZVI has been successfully formed. The resulting ZVI particles are spherical granules with heterogeneous sizes and close together or agglomerating. Based on the results, it was found that the optimum ratio between FeSO4 and polyphenols for ZVI preparation is 4 : 1. Based on the particle size distribution analysis, it was shown that the optimum feeding temperature and time for ZVI synthesis were 25 oC and 30 minutes, respectively.

Abstract

The research aims to determine the influence of aniline concentration and deposition time on the characteristics of polyaniline prepared using potentiostatic and galvanostatic electrodeposition methods. FTIR characterization data shows the typical peak of polyaniline in the form of the presence of a quinoid functional group at a wavenumber of 1596.16 cm-1. The typical diffraction pattern of polyaniline using XRD was detected at peaks of 2θ 21.1007o and 23.5995o. Polyaniline formed using SEM has a surface morphology that grows in a stacked and irregular manner and has a high conductance value so that it can be used as a substrate in Fe/Ni electrodeposition. The results of the Fe/Ni electrodeposition process when viewed using SEM cause the polyaniline surface morphology to be covered by a Fe/Ni alloy by having an elemental composition from the EDS test data, are iron (Fe) 68.15% and nickel (Ni) 24.83%. Fe/Ni levels from AAS data attached to PANI(pot)-Fe/Ni are 1.1912 ppm and 0.8288 ppm; in PANI(gal)-Fe/Ni are 1.2219 ppm and 0.8392 ppm.
