Study on Photocatalytic Cement Concrete for the Degradation of Textile Dyes

Abstract

This process is developed in the way that low level usage of chemical such as Titanium-di-oxide and urea along with the cement concrete structure for the photocatalytic activity under sunlight. When the cement concrete structure is introduced the sustainability of the process is increased so the efficient use of the reactant is achieved. From this study we obtained that the photocatalytic way of separation of waste ions can increase the purification process. The feed water is the waste from the common effluent plant with high in BOD and COD content. Two crystalline forms of TiO2, viz. anatase and rutile were tested for their photocatalytic activity. The extent of photocatalytic degradation was found to increase with increasing TiO2 concentration up to 2 g/L TiO2, 5 g/L urea above which degradation remained practically constant. Textile waste degradation was enhanced at acidic conditions and in the addition of hydrogen peroxide. For the assessment of catalyst activity on repeated use, experiments were performed; after thrice successive uses, TiO2 had sufficiently retained its photocatalytic activity and to perform the kinetic studies.
