Synthesis and characterization of Chromium(III) - curcumin complex / Nur Afiqah Muhamad Ludin

Curcumin can form strong colored chelates with transition metal's ions. In this study, six samples are prepared at different temperature and ratio. The samples are prepared at room temperature and 40°C. Meanwhile, the ratio of Chromium(III) : curcumin is prepared at 1:1, 1:1.5 and 1:2. The aim of this study is to find out the best ratio and temperature for the metal complexation. The samples are prepared using reflux and characterized using UV Vis Spectrometer, Fluorescence Spectrometer, FTIR and TGA. From the result, ratio of 1:2 is the best for reaction of metal complex. Thus the recommendation is to further study on ratio 1:2 in the application of photonic devices.
