APPLICATION CASE OF ULTRASONIC EXTRACTION
(1) When extracting asphaltene from oil shale with eight solvents such as benzene, the extraction rate is equivalent to 24 times that of Soxhlet's fat extraction method under the action of a sound field of 50 kHz and 400 W;
(2) When leaching a zinc sample containing 17.3% of zinc with a mixed solution of sodium hydroxide and ammonium chloride, the leaching rate can be greatly accelerated with 22 kHz, 100 W ultrasound;
(3) The sound field irradiation with a frequency of 20 kHz and powers of 100 W and 600 W can improve the rate of pyrethroids in powdery pyrethrum chrysanthemums extracted with n-hexane; ultrasonic homogenizer
(4) Ultrasonic irradiation at 24±2.5 kHz and 120 W ultrasonic irradiation extracts benzopyrene (a) in the environmental sample, and the vacuum sublimation method has unmatched extraction rate.
(5) High-intensity single-headed insertion ultrasonic field of 18.5kHz and 250W can increase the rate of cyanidation leaching gold;
(6) The 20 kHz shaped ultrasonic wave crusher was used to extract the total alkali of Leonurus Heterophyllus and its extraction was higher than that obtained by the general reflux method, and the extraction time was shortened. The extraction rate after refluxing for 2 h was 0.176%, while the extraction rate after ultrasonic extraction for 40 min was up to 0.248%; the ultrasonic homogenizer
(7) Ultrasonic irradiation with 1 MHz and 0.2 W/cm 2 for 15 min can accelerate the phase separation of separating Mo and W by 4 to 5 times with acidic phosphoric acid extractor; and using a 20 kHz, 19 W/cm 2 energy-generating ultrasonic wave The instrument can increase the extraction rate of Ga by 15 times; ultrasonic mixer
(8) Ultrasonic irradiation with 20 kHz and 47 W with mechanical stirring can increase the extraction rate of Ni by 4 to 7 times. At present, ultrasound has been applied to a large number of extraction technologies, large-scale production applications, mainly used in biological, chemical, pharmaceutical. With the development of the industry and the increase in demand, ultrasonic extraction technology has occupied an important position. Ultrasonic extraction equipment
