A Preliminary Study of Synthesized Fluorescence Carbon Nanoparticles from Lignin Residual Liquid
: Lignin residual liquid is a macromolecule compounds resulted from the delignification process of empty bunches of palm oil within alkaline condition. This study reports the potential results of lignin residual liquid as the precursor of fluorescence carbon nano-particles synthesized from heating treatments. The characteristics of samples were tested by using FTIR, Spectrophotometry UV-Vis, and UV-lights observation. The results showed that FTIR spectra confirmed the functional groups of hydroxyl, while the visible spectrum displayed none absorbance. The UV spectrum displayed varied peaks from 214 to 319 nm which indicated different absorbance features within highly alkaline condition, whereas green-neon colour was shown under the UV-lights. This implies that various fluorescence properties occur from this study.
