Effectiveness of Using Laser to Extract Valuable Material from Vinasse

Abstract

The aim of this study was to investigate the product of treatment of vinass by laser and to convert it into valuable materials. For this purposes, vinass sample was burned for 30 s using Nd: YAG laser with output power 60 W. The product of this process was characterized by X-ray diffractometer (XRD), Fourier transform infrared (FTIR) and X-ray Fluorescence (XRF) so as to investigate its crystal structure and chemical components and elements. XRD results of the treated vinass showed Iron Silicide and Sodium Carbonate – Beta in different phases. FTIR showed a number of absorbance peaks attributed to Iron Silicide and Sodium Carbonate, also percentages of 0.27% from iron, 0.06% from chrome and 0.01% from nickel were found using XRF.
