Yam ntxwv ntawm Ultrasonic Extraction

Cov yam ntxwv ntawm ultrasonic extraction

Ultrasonic nkaus rau kua kua, ua kua-theem ob theem, ntau theem, hluavtaws qhov system thiab daim nyias nyias kaw qhov system yuav tsim cov kev ua haujlwm ntawm lub cev thiab cov tshuaj, thiab tsim muaj ntau yam ntxiv xws li cov nyhuv ntswj thiab perturbation hauv micro- ib puag ncig. Teeb meem, teebmeem ntawm teebmeem, thiab lub zog-concentration tsis yooj yim tau los ntawm qee cov lus txhais tau tias.

Ultrasonic extraction tshuab yog ceev, pheej yig, thiab muab piv rau cov pa luam yeeb cov pa luam yeeb.

Piv nrog Soxhlet extraction, nws qhov zoo tshaj plaws yog: 1 qhov tsim, txhim khu lub polarity ntawm lub system, txhim kho cov extraction, thiab ua kom tau raws li los yog ntau tshaj li qhov ua tiav ntawm Soxhlet extraction; 2 ultrasonic extraction tso cai rau ntxiv cov co-extractant kom ntxiv Ua kom muaj lub cev ntawm qhov hnyav; 3 yog tsim rau cov extraction ntawm kev xeem tivthaiv uas yog tsis tshav kub resistant; 4 cov sijhawm ua haujlwm luv dua Soxhlet extraction, feem ntau tsuas yog 24 txog 40 feeb xwb.

Ultrasonic extraction thiab supercritical kua extraction (SFE) sib piv: 1 ntsuas yog yooj yim, tus nqi extraction yog ntau tsawg; 2 tau extract ntau yam kev sib txuas, tsis hais lawv cov polarity, vim ultrasonic extraction siv tau ntau cov kuab tshuaj. SFE yog tsuas yog muab rho tawm nrog CO2 Tus neeg sawv cev no tsuas yog tsim rau cov extraction ntawm cov khoom tsis-ncov qaum.

Ultrasonic extraction thiab microwave-pab tau extraction sib piv: 1 Tej zaum, sai dua microwave-pab tau extraction; 2 kua qaub av kua qaub, ultrasonic extraction muaj kev ruaj ntseg dua cov pa microwave-pab tau extraction.

Ultrasonic extraction muaj dav adaptability thiab tsis txwv los ntawm polarity ntawm lub phiaj tivthaiv thiab molecular phaus. Tsis tas li ntawd, lub Extract muaj tsawg impurities, thiab lub Cheebtsam yuav tsum tau kuaj yog yooj yim sib cais thiab lim. Ultrasonic extraction tau tshem tawm los sis txo kev siv cov extractants kom txo tau cov pa phem ntawm cov kuab tshuaj.
