I-Al-Fumaric Acid MOF, edla ngokubizwa ngokuba yi-Al-FUM, yiMetal Organic Framework (MOF) ebonakaliswe ngefomula yayo yeekhemikhali i-Al (OH) (fum) .xH2O, apho x malunga ne-3.5 kwaye iFUM imele i-ion ye-fumarate. I-Al-FUM yabelana ngesakhiwo se-isoreticular kunye ne-MIL-53 (Al)-BDC eyaziwayo, kunye ne-BDC emele i-1,4-benzenedicarboxylate. Le MOF yakhiwe ngamatyathanga entsimbi ekwabelwana ngekona i-octahedra edityaniswe yi-fumarate ligands, idala i-lozenge-shape-shaped one-dimensional (1D) imingxuma enemilinganiselo esimahla emalunga ne-5.7×6.0 Ås2.
Enye yeenzuzo eziphambili ze-Al-MOFs, kuquka i-Al-FUM, yi-hydrothermal yabo ekhethekileyo kunye nokuzinza kweekhemikhali, eziququzelela imveliso yazo enkulu kwaye ibenze bafanelekele uluhlu lwezicelo zoshishino. Ngokukodwa, bagqwesa kwiinkalo ze-adsorption yolwelo, ukwahlukana, kunye ne-catalysis, apho ukuzinza kwabo kunye nokunyaniseka kwesakhiwo kubaluleke kakhulu.
Uzinzo lwamanzi olubalaseleyo lwe-Al-FUM luyi-asethi ebalulekileyo ekuvelisweni kwamanzi okusela. Ingasetyenziswa kwiinkqubo zokujiya kunye nokucoca ukuqinisekisa ukhuseleko kunye nomgangatho wamanzi okusela. Olu phawu lubaluleke kakhulu kwimimandla apho ukufikelela kumanzi acocekileyo kulinganiselwe okanye apho imithombo yamanzi ingcolisekile.
Ngaphaya koko, ukuguqulwa kwe-Al-FUM kwi-membrane esekwe kwi-MOF inika ithuba elinomdla lokwandisa umda wesicelo. Ezi membrane zinokuqeshwa kwiinkqubo ze-nanofiltration kunye ne-desalination, igalelo kumzamo wehlabathi jikelele wokujongana nokunqongophala kwamanzi kunye nokuphucula umgangatho wamanzi.
Ubume obungenabutyhefu be-Al-FUM, kunye nobuninzi bayo kunye nokusebenza kakuhle kweendleko, kuyibeka njengento ethembisayo yokusetyenziswa kukhuseleko lokutya. Usetyenziso lwayo lunokubanakho ukomeleza ukhuseleko lwekhonkco lonikezelo lokutya ngokubonelela ngeendlela zokubona kunye nokususa izinto ezingcolisayo eziyingozi.
Ngokubhekiselele kwiipropati ezibonakalayo, i-Al-FUM ifumaneka njengomgubo ocolekileyo kunye nobukhulu beqhekeza elingaphantsi okanye elilingana ne-20 μm. Lo bungakanani bamasuntswana, obudityaniswe nommandla othile ongaphezulu kwe-800 ㎡/g, negalelo kumthamo wayo ophezulu wokubhengeza. I-pore size ye-0.4 ukuya kwi-0.8 nm ivumela ukusefa kwe-molecular echanekileyo kunye ne-adsorption ekhethiweyo, okwenza i-Al-FUM ibe ngumviwa ofanelekileyo kwiinkqubo ezahlukeneyo zokwahlukana.
Isishwankathelo, i-Al-FUM yi-MOF eguquguqukayo kwaye eyomeleleyo enoluhlu olubanzi lwezicelo ezinokubakho, ukusuka kunyango lwamanzi kunye nokucocwa ukuya ekudalweni kweembrane eziphambili zokuhluza kunye nokuchithwa kwetyuwa. Ubume bayo obungeyotyhefu, bubuninzi, kwaye bufikelelekayo buyenza ibe ngumgqatswa owomeleleyo wokusetyenziswa kushishino lokutya, iphucula ukhuseleko kunye nomgangatho. Ngophando oluqhubekayo kunye nophuhliso, i-Al-FUM ilungele ukudlala indima ebalulekileyo ekujonganeni nemingeni enzima kakhulu yehlabathi, ngokukodwa kwimimandla yamanzi kunye nokhuseleko lokutya.
