Photocatalytic Decolorization of Methyl Orange by Silica-Supported TiO2 Composites
Immobilization of TiO2 on silica gel has been proposed to enable easy separation of the catalyst in aqueous systems after photocatalytic reaction. Our simple synthesizing method reduces production cost, and the photocatalyst could find economical application in wastewater treatment. Silica-supported TiO2 composites were prepared by molten salt method at 500, 600 and 700 °C for 60 min. The obtai...
متن کاملEnhanced pH and thermal stabilities of invertase immobilized on montmorillonite K-10
Invertase was adsorbed onto micro-porous acid-activated montmorillonite clay (K-10) by two procedures, namely adsorption and covalent binding. The immobilized enzymes were characterized by XRD, surface area measurements and Al NMR. XRD measurements revealed an expansion of clay layers due to immobilization which suggests that intercalation had taken place. Surface area measurements also support...
متن کاملDECOLOURIZATION OF PAPER MILL EFFLUENT BY IMMOBILIZED CELLS OF Phanerochaete chrysosporium
Paper and pulp industrial waste waters are a major environmental concern. As the treatment of these effluents is a major problem, exploring novel and feasible biotechnological interventions is very important. Utilization of white rot fungi as a means of biological treatment seems to be a viable option. The study was undertaken to use immobilization technique and Phanerochaete chrysosporium, a c...
متن کاملKINETIC-SPECTROPHOTOMETRIC DETERMINATION OF TRACE AMOUNTS OF NITRITE BY THE REACTION OF METHYL ORANGE FORMATION
The composite diazotization coupling reaction of sulfanilic acid and N, Ndimethylaniline was used for the precise, accurate, and rapid determination of trace amounts of nitrite ion (0.02-3 µg/ml). The reaction was monitored spectrophotometrically by measuring the absorbance of the produced methyl orange at 510 nm by a fixed the method of 5.0 minutes. The relative standard deviation for the...
متن کاملActivity of Laccase Immobilized on TiO2-Montmorillonite Complexes
The TiO2-montmorillonite (TiO2-MMT) complex was prepared by blending TiO2 sol and MMT with certain ratio, and its properties as an enzyme immobilization support were investigated. The pristine MMT and TiO2-MMT calcined at 800 °C (TiO2-MMT800) were used for comparison to better understand the immobilization mechanism. The structures of the pristine MMT, TiO2-MMT, and TiO2-MMT800 were examined by...
