CaTiO3 Perovskite in the Photocatalysis of Textile Wastewater Ana Maria Ferrari Talitha Oliveira Germiniano Jaqueline Elisabete Savoia Rubiane Ganascim Marques Valquíria Aparecida dos Santos Ribeiro Ana Cláudia Ueda 10.6084/m9.figshare.8227535.v1 https://scielo.figshare.com/articles/dataset/CaTiO3_Perovskite_in_the_Photocatalysis_of_Textile_Wastewater/8227535 <div><p>Abstract Perovskite-type CaTiO3 material was synthesized by the polymeric precursor method and characterized. The powder was applied as a promising alternative to TiO2 photocatalyst. Photocatalytic reaction parameters were optimized by surface analysis methodology on the degradation of methylene blue under UV radiation. After optimization, complex textile- and tannery wastewaters were treated and the COD reduction was evaluated. At optimized conditions (pH=11.2 and 1 g L-1 of catalyst concentration), the results obtained for the photodegradation of the real wastewater after 240 min of irradiation were 45% COD reduction for both effluents. The reactions were adjusted to the pseudo first order kinetic and the rate constants were 2.07 x 10-3 (min-1) and 2.23 x 10- 3 (min-1) for COD reduction for textile- and tannery wastewaters, respectively.</p></div> 2019-06-05 02:57:59 calcium titanate dye photocatalyst real wastewater response surface analysis.
