TOLERANCE AND REMOVAL OF ZINC (II) AND MERCURY (II) BY DEAD BIOMASS OF ASPERGILLUS TUBINGENSIS MERV4

Abstract

synthesized by solid by solid (SSI), sol-gel (SGI), and incipient wetness impregnation (IWI)

techniques. The catalysts were characterized by X-ray diffraction (XRD), SEM, Raman

spectroscopy, surface area analysis (BET), and Fourier transforms infrared spectroscopy. Ex-situ

structural studies by X-ray diffraction and Raman scattering showed that the anatase phase is

maintained throughout the 10% of Pt or Os on Titania phase. The experimental demonstrated that

supported platinum and osmium are active catalysts at moderate temperature for the complete

oxidation of CO to CO2; The SSI method gave the most active catalysts for both Pt and Os. Pt

catalysts prepared by SSI were active at temperature below 100°C and showed a much greater
