KARAKTERISASI NANO PARTIKEL ABU SEKAM PADI DENGAN MENGGUNAKAN METODE KOPRESIPITASI

The purpose of this research is the manufacture of nano particles of rice husk ash (ASP) and the characterization of the properties of nano-particles with a method that will be prepared coprecipitasi. ASP obtained from rice refinery combustion products has white color .This method is performed in the manufacture of nano-particles by means of ASP in Ball mill for an hour to get a size of 200 mesh and then synthesized with a solution of HCl 2 M ,NaOH 2.5 M by methods coprecipitation so it is expected to obtain nano-particle ASP 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 atom ASP 50.77nm with a crystal system Tridymite SiO2, Triclinic, F1 (1), XRF analysis results obtained dominant SiO2 content.
