Synthesis of Chlorophyll Thin Film from Noni Leaves via Dip Coating Process
Chlorophyll is a green pigment responsible for the photosynthesis processes that occur in the green leaf. The chlorophyll pigment can be extracted from green leaf using simple solvent solution as a function of solar energy conversion. Dip coating onto glass slide was applied to produce a thin film of Noni leaves chlorophyll. The Noni leaves chlorophyll thin films were analyzed using scanning electron microscopy (SEM), X-ray diffraction (XRD) and ultra violet visible (UV-Vis). The micrograph of SEM shows that the shapes were found in various shapes. The UV-Vis analysis revealed that the extracted chlorophyll had three absorbance spectra at 433 nm, 464 nm and 664 nm. These show that the extracted chlorophyll contains both chlorophyll-a and chlorophyll-b in the mixture.
