Analysis of Rice Husk Ash Nanoparticles with Polyethylene Glycol Surfactants -6000 Using Coprecipitation Method

Abstract

The purpose of this research is the preparation of nano particles of rice husk ash (RHA) and the characterization of the properties of nano-particles with a method that will be prepared coprecipitation.RHA obtained from rice refinery combustion products has white color .This method is performed in the manufacture of nano-particles by means of RHA in ball mill for an hour to get a size of 74 µm and then synthesized with a solution of HCl 2 M ,NaOH 2.5 M and sintesis polyethyelene glycol (PEG) 6000 (1:3;1:4 and 1:5)by methods coprecipitation so it is expected to obtain nanoparticle RHA then be characterized namely by analyzing the composition by means of X-Ray Fluorescent (XRF), morphology analysis by scanning Electron Microscofe (SEM), X-ray structure analysis Difraction (XRD). XRD analysis results obtained by the size of the crystal  RHA  52,22 nm, 47,84 nm and  54,54 nm with a crystal system tetragonal ,XRF analysis results obtained dominant SiO₂ content 99,3 % by weight. Morfology results does not occur agglomeration RHA.
