摘要: In this study, the photocatalysis of Alphazurine FG as a model water pollutant, by white Portland cement samples modified with different TiO2 nanomaterials (TiO2 in form Degussa P25, Millennium PC500, PC105 and anatase-Merck), was investigated. The pseudo first-order rate constants were compared degradation unmodified sample. A significant enhancement photocatalytic activity due to addition P25 observed. crystalline phase, average size surface area photocatalyst found have influence on nanostructured TiO2-modified samples. presence TiO2–P25/cement experimentally studied through changing UV light intensity initial dye concentration. electrical energy consumption estim...
