Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Sonocatalytic process was adopted to enhance the decolorization and mineralization of wastewater containing amaranth dye. Zeolite Y was used as the support material and modified using three different active metals i.e. Ti, La and Fe.The modification of the encapsulated TiO2 by Fe metal enhanced the decolorization efficiency of amaranth dye more efficiently than its modification with La metal. The maximum decolorization efficiency was about 97 % with maximum COD removal of 57 % after 120 min of reaction. The catalytic reaction was assisted by an ultrasonic irradiation source at 50 W for the output power and the frequency was 40 kHz. Different operational parameters were investigated for the best of higher catalytic activity.The developed sonocatalysts were successfully characterized using different characterization techniques.The Fe ions loaded onto encapsulated titanium caused a significant reduction in band gap energy from 3.55 eV for bare TiO2 to 2.8 for Fe loaded on encapsulated (0.8%Fe/Ti-NaY). The synthesized sonocatalyst possessed high surface areas and demonstrated high reusability potential for many consecutive cycles with acceptable amount of Fe leaching. 116 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Two different types of titanium precursor i.e. potassium titanium oxalate and tetrabutyl orthotitanate were used to investigate the characteristics and catalytic performance of Fe-TiO2 supported zeolite. The activity of the catalyst was tested for the degradation of amaranth dye under ultrasonic irradiation with output power of 50 W and 40 kHz frequency.The XRD results indicated that the type of titanium precursor significantly effects on the crystallinity of the produced catalysts. The AFM results detected a drastic reductions in the roughness of the catalyst synthesized using potassium titanium oxalate compared to the catalyst synthesized using tetrabutyl orthotitanate as titanium precursor. The reusability and stability of the produced catalysts were investigated after three consecutive cycles. The results revealed that the catalyst synthesized using tetrabutyl orthotitanate was able to keep its high efficiency with minor drop in catalytic activity to about 90% compared to that using potassium titanium oxalate with catalytic activity of 24% after three consecutive cycles. 124 pp. Englisch.…
