Synthesis and characterization of iron(ii)-curcumin complex / Siti Nor Aini Md Shari

Curcumin is a yellow powder solid which is widely used in medical area.However this study focusing on photonic area. The preparation of Fe(II)-curcumin complex by different ratio (1:1, 1:1.5 and 1:2) and temperature at 25oC and 40oC was studied. Only Curcumin vary in mole ratio not the metal Iron(II). After that, the samples were characterized by using UV-Vis spectroscopy, Fluorescence spectroscopy, FTIR and TGA. For overall in UV-Vis analysis the absorbance is increased when temperature increase. λmax also increased and the blue and red shift observed. Meanwhile for fluorescence result, 1:2 at 40oC is the optimum Stoke’s shift. In FTIR analysis, the changes in shift occurs indicate complexation involved. In TGA analysis, the all complex undergoes decomposition until formed iron oxide. As a conclusion, The optimum result is 1:2 at 40oC.
