I-Hielscher Ultrasound Technology

ultrasonic Soxhlet isizinda

  • I-Ultrasonics ithuthukisa isizinda esivamile soxhlet.
  • I ultrasonically basiza Isizinda Soxhlet kungaholela izitshalo ephakeme kanye izikhathi izikhathi iDemo.
  • Imishini ye-ultrasonic ingahlanganiswa kalula ne-classic Soxhlet.

Isizinda soSoxhlet

I-Soxhlet isisetshenziswa yindlela esetshenziswa njalo-liquid-liquid extraction in laboratories yokwenziwa noma ehlaziya futhi kuyadingeka lapho i-compound efunayo ibonisa kuphela ukulinganisa okulinganiselwe ku-solvent, futhi ukungcola akungenakutholakala kulowo mklamo. Ngamafuphi, inani elisebenzayo lesitshalo seSoxhlet lingachazwa njenge-reflux encibilikisiwe.
I-Ultrasound ihlanganiswe ngempumelelo ku-Soxhlet isizinda sokwandisa isivuno nokunciphisa isikhathi. Lapho isikhumba seSoxhlet siphelile, isisombululo sisuswa (isib. Usebenzisa i-evaporator ejikelezayo).

Inkinga:

Isizinda seSoxhlet sendabuko sinokulimaza okukhulu ngenxa yesikhathi eside sokukhipha isikhathi futhi inani elikhulu le-solvent elisetshenzisiwe. Ngaphezu kwalokho, ku-extractor weSoxhlet evamile akukho ukuqubuka kungahlanganiswa ukusheshisa inqubo yokukhipha. Njengoba kusetshenziselwa ukuxazulula okuningi, kusetshenziselwa ukufudumala kwamandla okushisa okukhulu kanye nokuhlushwa okukhulu. Ngokuvamile, amakhemikhali e-thermo labile target ahlukaniswa njengoba izinto zivezwa ngesikhathi sokuthatha isikhathi eside ukushisa kwendawo yokubilisa ye-solvent.

Isixazululo: Extraction Ultrasonic Soxhlet

I-ultrasound enamandla yenza ukwedluliswa okukhulu phakathi kwesampula ne-solvent. Ngalokho, ukusetshenziswa kwe-solvent kungancishiswa noma kugwenywe ngokuphelele. Isikhathi sokukhipha sincishiswe kakhulu ukuze okukhishwayo kungabonakali esikhathini sokushisa eside. Lokhu kusho ukuthi ukubola kokukhipha kungagwenywa.
I-Ultrasound ingahlanganiswa kalula ku-setup ye-Soxhlet yesikhumba – noma ngokufaka uphondo lwama-ultrasonic ekamelweni likaSoxhlet noma nge-sonication ikamelo leSoxhlet ngokungaqondile ngodonga lwesakhiwo. I ultrasonic Soxhlet isizinda kuphumela ku isivuno esiphezulu ngaphakathi isikhathi esifushane sokukhipha ngaphansi okunamandla izimo zokukhipha.

“I-ultrasonication njengendlela yesikhumba kuyindlela ephumelelayo uma kuqhathaniswa nezindlela ze-reflux zokukhipha umkhondo wezinto eziphilayo ezivela emhlabathini nasemidlelweni. Amasu okuqothula ama-ultrasonic avele ekhiqiza inani elilinganayo noma elikhulu (Song et al., 2002) lama hydrocarboni kunezinye izindlela zokukhipha […]. Kuye ngohlobo lwe-contaminants kanye ne-matrix, i-sonication ingaba nenzuzo yezikhathi zokususa ngokushesha. Ukuhlelwa kwe-ultrasonic extraction parameters, kufaka phakathi uhlobo lwe-solvent noma ukwakhiwa kwe-solvent, isikhathi sokukhipha, isampuli yokulayisha, nokuqukethwe kwamanzi kudinga izikhathi eziningi ukuze kwenziwe okunye okuphumelelayo nokukhiqiza kabusha (Berset et al., 1999). Amasu okusebenzisa i-Ultrasonication ngokuvamile ahlinzeka ngendlela ephansi kakhulu yokusebenzisa izindleko, esebenzisa imiqulu emincane ye-solvent ngaphandle kokudinga i-Glassware ne-instrumentation.”

I-Soxhlet ehlangene ne-sonication iholela ekuvuneni okuphezulu kanye nezikhathi ezincane zokukhipha (Chofoza ukuze ukhulise!)
