Al-Fumaric Acid MOF, yomwe nthawi zambiri imatchedwa Al-FUM, ndi Metal Organic Framework (MOF) yodziwika ndi mankhwala ake Al(OH)(fum).xH2O, pomwe x ndi pafupifupi 3.5 ndipo FUM imayimira fumarate ion. Al-FUM imagawana mawonekedwe a isoreticular ndi MIL-53(Al)-BDC yodziwika bwino, yomwe BDC imayimira 1,4-benzenedicarboxylate. MOF iyi imapangidwa kuchokera ku maunyolo azitsulo zogawana ngodya za octahedra zolumikizidwa ndi fumarate ligands, kupanga ma pores amtundu umodzi (1D) okhala ndi miyeso yaulere pafupifupi 5.7 × 6.0 Å2.
Chimodzi mwazabwino zazikulu za Al-MOFs, kuphatikiza Al-FUM, ndi kukhazikika kwawo kwapadera kwa hydrothermal ndi mankhwala, komwe kumathandizira kupanga kwawo kwakukulu ndikuwapangitsa kukhala oyenera kugwiritsa ntchito mafakitale osiyanasiyana. Makamaka, amapambana m'magawo amadzimadzi adsorption, kupatukana, ndi catalysis, komwe kukhazikika kwawo ndi kukhulupirika kwawo ndikofunikira.
Kukhazikika kwamadzi kwa Al-FUM ndi chinthu chofunikira kwambiri popanga madzi akumwa. Itha kugwiritsidwa ntchito poyeretsa komanso kuyeretsa kuti madzi akumwa akhale otetezeka komanso abwino. Izi ndizofunikira makamaka m'madera omwe mwayi wopeza madzi abwino ndi ochepa kapena kumene madzi ali ndi kachilombo.
Kuphatikiza apo, kusinthika kwa Al-FUM kukhala nembanemba zochokera ku MOF kumapereka mwayi wosangalatsa wokulitsa kuchuluka kwake. Ma nembanembawa atha kugwiritsidwa ntchito m'njira zopangira nanofiltration ndi kuchotsa mchere, zomwe zimathandizira kuyesayesa kwapadziko lonse kuthana ndi kusowa kwa madzi komanso kukonza madzi abwino.
Mkhalidwe wopanda poizoni wa Al-FUM, limodzi ndi kuchuluka kwake komanso kutsika mtengo kwake, umayiyika ngati chinthu chodalirika chogwiritsa ntchito chitetezo chazakudya. Kugwiritsa ntchito kwake kumatha kupititsa patsogolo chitetezo cha njira yoperekera chakudya popereka njira yodziwira ndikuchotsa zowononga zowononga.
Pazinthu zakuthupi, Al-FUM imapezeka ngati ufa wabwino wokhala ndi tinthu tating'onoting'ono kapena tofanana ndi 20 μm. Kukula kwa tinthu tating'onoting'ono, kuphatikizidwa ndi malo enaake opitilira 800 ㎡/g, kumathandizira kutulutsa kwake kwakukulu. Kukula kwa pore kwa 0.4 mpaka 0.8 nm kumalola kuwerengetsa kwachindunji kwa ma cell ndi kutsatsa kosankha, kupangitsa Al-FUM kukhala woyenera panjira zosiyanasiyana zolekanitsa.
Mwachidule, Al-FUM ndi MOF yosunthika komanso yolimba yokhala ndi njira zambiri zomwe zingagwiritsidwe ntchito, kuyambira kuchiritsa madzi ndi kuyeretsa mpaka kupanga zingwe zapamwamba zosefera ndi kuchotsa mchere. Chikhalidwe chake chopanda poizoni, chochuluka, komanso chotsika mtengo chimapangitsanso kuti chikhale choyenera kugwiritsidwa ntchito m'makampani azakudya, kumapangitsa chitetezo ndi khalidwe. Ndi kafukufuku ndi chitukuko chomwe chikuchitika, Al-FUM yatsala pang'ono kuchitapo kanthu pothana ndi mavuto omwe akukumana nawo padziko lonse lapansi, makamaka pankhani ya madzi ndi chitetezo cha chakudya.
