摘要：Synthesis of titanium dioxide coated activated carbon (TiO2/AC) has been undertaken using sol-gel method and its application in Rhodamine B (RB) dye removal has been investigated.The synthesized sonocatalyst (TiO2/AC) was characterized by using SEM and FTIR techniques.The effects of the TiO2/AC on the sonocatalytic degradation of RB dye and the operational parameters such as pH, temperature, ultrasonic frequency with the presence/absence of sonocatalyst of the sonocatalytic degradation of RB were concerned in this study.The degradation efficiency of RB in aqueous solution could be achieved 82.21% with the addition of TiO2/AC at the best conditions.The best conditions for sonocatalytic degradation of RB were found to be pH 6, at temperature 50°C, under ultrasonic frequency of 30 kHz with the presence of sonocatalyst for 60 minutes.
