Figure 1From: Novel Crystalline SiO2 Nanoparticles via Annelids Bioprocessing of Agro-Industrial WastesIR bands to synthesis of nanoparticles SiO2 obtained for vermicompost. The Figure show the bands more representatives to SiO2 to in rice husk, sugarcane bagasse and coffee husk at temperature of calcination: 500, 600 and 700°C. Representative bands for Aerosil® 130 too are shownBack to article page
