    Author: Wang S, Huang B, Wang Y, Liao L.
    Journal: Ultrason Sonochem; 2006 Sep; 13(6):506-10. PubMed ID: 16377231.
    Abstract:
    The comparison of enhancement effect of pentachlorophenol sonolysis at 20 kHz by different dual-frequency ultrasonic irradiations has been investigated. Dual-frequency (20 kHz/40 kHz, 20 kHz/530 kHz, 20 kHz/800 kHz and 20 kHz/1040 kHz) ultrasounds have been used. It has been found that the rate of pentachlorophenol degradation at dual-frequency ultrasonic irradiation is the highest compared to mono-frequency ultrasonic systems. The combination of dual-frequency systems has synergistic effect and the enhancement effect of sonochemical degradation of pentachlorophenol at 20 kHz by dual-frequency systems appears to be remarkable frequency sensitive. The order of contribution to the enhancement effect of sonochemical degradation of pentachlorophenol at 20 kHz is as follows: 530 kHz > 800 kHz > 40 kHz > 1040 kHz.
