DAIM NTAWV THOV NTAWM ULTRASONIC EXTRACTION
(1) Thaum extracting asphalene los ntawm cov roj shale nrog cov roj xya xws li benzene, cov lej extraction yog sib npaug li 24 zaus uas Soxhlet cov roj extraction txoj hauv qab ntawm qhov kev tawm suab ntawm 50 kHz thiab 400 W;
(2) Thaum leaching zinc qauv uas muaj 17.3% zinc nrog cov kua sib tov kua sodium hydroxide thiab ammonium chloride, qhov leaching tus nqi yuav ua rau kom ceev nrooj nrog 22 kHz, 100 W ultrasound;
(3) Lub suab teb irradiation nrog ib zaus ntawm 20 kHz thiab powers ntawm 100 W thiab 600 W yuav ua kom tus nqi ntawm pyrethroids hauv powdery pyrethrum chrysanthemums muab rho tawm nrog n-hexane; ultrasonic homogenizer
(4) Ultrasonic irradiation ntawm 24 ± 2.5 kHz thiab 120 W ultrasonic irradiation cia benzopyrene (a) nyob hauv ib qho qauv, thiab lub nqus sublimation txoj kev muaj unmatched extraction tus nqi.
(5) High-intensity insertion ultrasonic teb ntawm 18.5kHz thiab 250W yuav nce tus nqi ntawm cyanidation leaching kub;
(6) Lub 20 kHz li ultrasonic yoj crusher tau siv los rho tawm cov alkali tag nrho ntawm Leonurus Heterophyllus thiab nws cov extraction yog siab tshaj uas tau los ntawm kev dav dav dav reflux txoj kev, thiab lub sij hawm extraction tau luv. Lub extraction tus nqi tom qab refluxing rau 2 h yog 0.176%, thaum lub extraction tus nqi tom qab ultrasonic extraction rau 40 min yog mus txog 0.248%; tus ultrasonic homogenizer
(7) Ultrasonic irradiation nrog 1 MHz thiab 0.2 W / cm 2 rau 15 min tau leem theem sib cais ntawm Mo thiab W los ntawm 4 mus rau 5 zaug nrog acidic phosphoric acid extractor; thiab siv 20 kHz, 19 W / cm 2 energy-generating ultrasonic yoj Lub ntsuas yuav ua rau kom qis qis ntawm Ga los 15 zaug; ultrasonic tov khoom
(8) Ultrasonic irradiation nrog 20 kHz thiab 47 W nrog mechanical stirring yuav ua rau kom tus nqi extraction Ni ntawm 4 rau 7 zaus. Tam sim no, ultrasound tau raug siv rau ntau tus extraction yees, daim ntaub ntawv ntau ntau lawm, mas siv tshuaj lom, tshuaj, tshuaj. Nrog rau txoj kev lag luam thiab qhov nce hauv kev xav tau, ultrasonic extraction tshuab tau nyob hauv ib txoj hauj lwm tseem ceeb. Ultrasonic extraction khoom
