SYNTHESIS OF FOAM GLASS WITH IMMOBILIZED ZINC OXIDE FOR PHOTODEGRADATION OF ALIZARIN S IN AQUEOUS SOLUTION
Journal Title: Periódico Tchê Química - Year 2017, Vol 14, Issue 27
Abstract
The treatment of effluents is essential for the maintenance of the quality of water resources. Among the treatments used, photodegradation is on the rise. Although it is promising, the separation/recovery of photocatalysts in suspension is laborious and costly. In addition, the incorrect disposition of residues causes concern, for example, the glass originated from fluorescent lamps, which presents difficult destination and recovery. In this context, the objective of this work was to synthesize foam glass as substrate for the catalyst (ZnO), from glass residues of fluorescent lamps applying CaCO3 as foaming agent, observing the efficiency of this material in the photodegradation of Alizarin S dye in aqueous solution. To obtain the catalyst foam glass, the characterization was made on the glass and in the foaming agent, followed by its formulation, conformation and burning. Finally, the dye photodegradation tests were done. The results allow to conclude that the foam glass show a great potential as a support for ZnO in catalyzed photodegradation techniques, presenting very similar results when compared to suspended ZnO. It is worth mentioning that the material produced reduces the environmental impact caused by incorrect allocation of fluorescent lamps and solves a problem in the effluent treatment process.
