I-Adsorption Ephakeme Nge-Alumina Ball

Amabhola e-Alumina afaka indawo ethile emangalisayo engu-280m 2 nge-g ngayinye ethuthukisa amandla e-adsorption futhi isetshenziswa ekumisweni kwegesi njengenqubo yeClaus ukuze imunce umhwamuko futhi ivimbele ukusabela kwe-hydrating.

Izinto ze-Desiccant zinezakhiwo ezahlukene ezisebenza ngokuphumelelayo ngaphansi kwamazinga okushisa ahlukahlukene. I-Alumina iyindlela efanelekile yokufakwa kwegesi eyomile enamazinga okushisa aphezulu.

Ukususa Umswakama Okuthuthukisiwe

Ukungcoliswa komswakama kwezinqubo zokuhluza uwoyela kuyinkinga evame, okuholela ekugqwaleni nasekucekeleni phansi imishini. Ngamabhola abo e-alumina aphakeme akwazi ukukhipha umswakama emifudlaneni ecwengiwe ngaphandle kokululaza ikhwalithi noma ukusebenza kwezinqubo..

Ucwaningo lwamanje luhlola ukuhlanganiswa kwemfucuza esekwe ngaphambili kwe-alumina-based adsorbent kusetshenziswa imvula nezindlela zokubala ukuze kususwe ama-molecule amathathu kadayi.: I-Methylene Blue (MB), I-Crystal Violet (I-CV) kanye ne-Basic Fuchsin (BF) kusuka kumasistimu anamanzi kusetshenziswa imvula elandelwa ukubala. I-Adsorbent ihlolwe kusetshenziswa i-FTIR, Ukuhlaziywa kwe-XRD ne-SEM ukuze kubonakale izakhiwo zayo zesakhiwo ngenkathi kusetshenziswa ama-isotherm e-N2 adsorption-desorption ukuze kuhlolwe amandla ayo okukhipha ama-molecule odayi. (MB), I-Crystal Violet (I-CV) kanye ne-Basic Fuchsin (BF).

I-CeZ-ball yalungiswa nge-PVA binder ye-As(III) i-adsorption. Ukuhlolwa kwe-CeZ-ball njenge-As(III) ukumunca kwenzeke kukholomu yokugeleza kombhede ongashintshi; ifilimu yayo kanye nama-pore diffusion coefficients, kanye nenombolo ye-Biot nayo yahlolwa.

Ukukhiqiza Okukhulisiwe

Umswakama ungaba umthombo omkhulu wokugqwala kanye nokulimala kwemishini phakathi nezinqubo zokucwenga uwoyela, okuholela ekubambezelekeni okubizayo kanye nokuncipha kokukhiqiza. Amabhola e-alumina acushiwe afakazele ukuthi asebenza kahle kakhulu ekuqedeni ukunqwabelana komswakama ukuze kusebenze kahle kakhulu kanye nesikhathi sokuphumula esincishisiwe..

Indlela yokususa i-alumina ecushiwe ye-chlorine incike ku-chemisorption, ngezimbotshana zayo eziheha ama-molecule e-chlorine ngamabhondi amakhemikhali ukuze anikeze amandla okukhangisa aphezulu ngisho nasezindaweni eziphansi zokugxila.. Ngaphezu kwalokho, I-alumina ecushiwe ingaphinda igaywe kabusha futhi iphinde isetshenziswe ngokuphindaphindiwe kunciphisa izindleko zokusebenza ngokuhamba kwesikhathi.

Amadesiccant ethu e-alumina afaka osayizi bobuhlalu obufanayo ukugwema umzila, okubalulekile ekugcineni ukusebenza kahle kwe-adsorption kumakholomu agelezayo aqhubekayo. Futhi zinamandla okuchoboza aphezulu ukuze zigweme ukuphuka futhi zimelana nokushaqeka okushisayo nokuhuzuka. Ngaphezu kwalokho, I-alumina inokuminyana kwenqwaba ephansi ngaphandle kokuncipha, ukuvuvukala noma ukuthamba lapho kuvezwe emanzini; ukuyenza ibe yinto efanelekile yezinto ezisetshenziswa ngaphambi kokulala kumakholomu ombhede ongashintshi njengoba iphinda imelana nokuslugging kwamanzi awuketshezi ukuvimbela ukuvuza nokuphazamiseka ngesikhathi senqubo yokukhanga..

Izindleko Zamandla Ezehlisiwe

I-alumina ecushiwe inikeza indawo engaphezulu kakhulu kunamabhola e-ceramic ukuze amunce ngempumelelo amakhemikhali nezinyibilikisi, ukumelana nokushaqeka okushisayo, ukuhuzuka, ukuncipha noma ukuvuvukala ngenxa yokumuncwa kwamanzi; okwenza kube yinto ebalulekile ye-desiccant kuzilungiselelo zezimboni.

Kulolu cwaningo locwaningo, ama-alumina nanocrystals asetshenziswa ukukhangisa i-Orange G (KANYE) dayi kusuka kuzixazululo ezinamanzi usebenzisa i-batch adsorption. Amapharamitha enqubo ahlukene ahloliwe futhi alungiswa. I-Kinetics, Izifundo ze-isotherm kanye ne-thermodynamic nazo zenziwa ukuze kutholwe ukuqonda okwengeziwe kwendlela ye-adsorption..

Iziza ze-Adsorption isotherms zibonise ukuthi ukususwa kwe-OG kwakuqhutshwa yizo zombili izinqubo zefilimu kanye ne-pore diffusion., nge 93.3 mg/g ibalwa ku 303 K kanye ne-pH 7.6 njengomthamo wayo omkhulu we-adsorption. Izinqubo zokusabalalisa kwangaphakathi zaboniswa ngeziqephu ezihlukene eziningi ze-qt iqhathaniswa no-t0.5 ngokusatshalaliswa kwezinhlayiyana ezingaphakathi..

Isondlo Esincishisiwe

Amabhola e-alumina acushiwe afaka indawo engaphezulu ethile ekhethekile, ukubenza babe ikhambi elikahle lokuhlunga ukungcola okuyingozi oketshezini noma emagesini. Ngaphezu kwalokho, ukungabi nabuthi nokunganambitheki kuphephe ngokuphelele ukusetshenzisa uhla lwezinhlelo zokusebenza kusukela ekucutshungulweni kokudla kuye ekukhiqizweni kwemithi.

Amabhola we-alumina abonisa amaza aphezulu phakathi 700-950 I-cm-1 ehambisana ne-octahedral ne-tetrahedral coordination systems yama-ion e-aluminium ezinhlelweni zabo zokuxhumanisa zesigaba se-g, okwenza lolu hlobo lwe-adsorbent lube yindlela ephumelelayo yokukhipha odayi ngamafomu okushaja ahlukahlukene, njengo-Orange G (KANYE), kusuka kuzixazululo ezinamanzi.

Amabhola e-alumina acushiwe asetshenziswa kabanzi njengezisekelo ze-catalytic ezimbonini ze-petrochemical ngenxa yekhono lazo lokuhlinzeka ngendawo ezinzile nengasebenziyo yama-catalysts., ukwandisa ukusebenza kahle kuyilapho belula isikhathi sabo sokuphila. Ngaphezu kwalokho, lawa mabhola anikeza isixazululo esisebenzayo sokuqeda i-fluoride emithonjeni yamanzi okuphuza njengoba iwamunca ebusweni futhi inikeza ukususwa okungabizi kakhulu ezinqubweni zezimboni kanye nezinqubo zezimboni..
