Abstract

Plant biomass is a potential lignocellulose material  for synthesis of carbon nano structure. Its characteristics as adsorbent and its size particle  make it good additive for liquid fertilizer. In this research, we study influence of sequential different  pressure pyrolysis methods (hydrothermal–microwave method and reflux–microwave method) toward characteristics of carbon nanostructure from sugarcane leaf biomass. Each reflux and hydrothermal method was adjusted at 200oC, then followed by microwave at 800W. Characterization showed that the hydrothermal - microwave method using X-ray diffraction indicates diffractogram patterns of both carbon nanostructure and cellulose. SEM micrographs show sphere and block shapes. FTIR spectra indicates different concentration of oxy surface functional groups. UV spectra of the dispersed product in water indicates  existence of aromatics C=C groups. The hydrothermal - microwave method resulted the product inwhich lower crystalinity index of cellulose, smaller particles, lower concentration of oxy surface groups than the reflux - microwave one. Correlation of chemical properties (aromaticity and fraction of polar groups) was more linier than of physical - chemical properties  (indexe of cellulose crystalinity and fraction of polar groups). The stability of colloid was indicated by dispersing technique in order of sonication < blending < blending - sonication.
