Frequency Ultrasound

The saturate granular activated carbon(GAC) which adsorbed Ni2+ is regenerated using dual-frequency ultrasound. The individual frequency is 45KHz, 80KHz and 100KHz respectively. The experimental results show that the regeneration efficiency using dual-frequency ultrasound is better than that using single- frequency ultrasound under the same experimental condition. When the two ultrasound’s frequency is 45KHz, the regeneration efficiency is 81.03%, comparing single- frequency ultrasound it increase by 40% and it is the best in six group dual-frequency ultrasound. In conclusion, the dual-frequency ultrasound regeneration showed a possibility as an alternative to chemical and thermal regeneration of GAC.
