Sezvo kunetseka kwepasi rose pamusoro pekushaikwa kwemvura nekusvibiswa kuri kuramba kuchiwedzera, kutsvaga matekinoroji ekurapa mvura anoshanda, asingadhuri, uye anogara kwenguva refu kwawedzera. Pamberi pekutsvaga uku pane alumina (Al₂O₃), kunyanya mumhando dzayo dzakagadzirwa neanu, idzo dzakabuda sezvinhu zvakakosha mukuchenesa mvura yekunwa, kurapa mvura yakasviba yemumaindasitiri, uye kuona kuti nharaunda yakachengeteka.
Simba rePorosity: Alumina Yakagadziriswa
Alumina yakabatidzwa, iyo ine maburi akawanda ealuminium oxide inogadzirwa nekubvisa mvura mualuminium hydroxide pakupisa kwakanyanya, inozivikanwa nekuda kwenzvimbo yayo yakakura (inowanzoita 250–1000 m²/g) uye kugona kwayo kunyungudutsa mvura. Kushandiswa kwayo kwakanyanya uye kwakasimbiswa ndiko kubviswa kwema fluoride ions mumvura yekunwa.
Kuwanda kwefluoride (inopfuura 1.5 mg/L) mumvura idambudziko repasi rose rinobata vanhu vanopfuura mamiriyoni mazana maviri, zvichikonzera zvirwere zvinokanganisa mazino nemapfupa. Alumina inoshandiswa inoshanda ne chemisorption, ichigadzira stable aluminium-fluoro complexes, zvichideredza fluoride zvakanyanya kuti isangane nezvinodiwa neWorld Health Organization (WHO). Inoshanda zvikuru munzvimbo dzakasiyana dzepH (3–12) uye inoshanda zvakanyanya mumamiriro ezvinhu asina kusimba (5.5–6.5).
Kupfuura fluoride, alumina yakakamurwa inobudirira mukubvisa simbi dzine chepfu nemetalloids, kunyanya arsenic. Kusvibiswa kwearsenic nemvura yepasi pevhu idambudziko guru rehutano hwevanhu munzvimbo dzakasiyana-siyana. Alumina yakakamurwa inopa dziviriro yakavimbika, ichibata mhando dzeAs(III) neAs(V), nokudaro ichidzivirira kupararira kwenguva refu uye kenza dzakabatana nadzo.
Zvishandiso zveMaindasitiri uye Zvepamusoro
Kushanda kwealumina hakungogumiri mumvura yekunwa yemumaguta. Munzvimbo dzemaindasitiri, inoshanda semushonga wekusvina mvura, inoomesa mhepo yakamanikidzwa, gasi rechisikigo, uye nzira dzakasiyana-siyana dzekugadzirisa nekukweva hunyoro. Inoderedzawo kupararira kwemvura inoyerera muboiler uye masisitimu ekutonhodza.
Kufambira mberi kwesainzi munguva pfupi yapfuura kwakaita kuti alumina ishandiswe mumabasa epamusoro-soro:
Nanotechnology: Nano-alumina (Al₂O₃ NPs) inopa nzvimbo yepamusoro uye reactivity isingaenzaniswi. Vaongorori vakabudirira kugadzira nanoparticles idzi kubva mufoil yearuminiyamu yakaraswa, vachigadzira adsorbent yegirini inodhura zvishoma, inokwanisa kubvisa lead (Pb²⁺) ions mumvura nekushanda kusvika ku98%.
Kuonza Kwemvura: Alumina inoshanda senzira yekutsigira zvinhu zvine simba guru. Zvinhu zvinoonza zvakaita seCo₃O₄/Al₂O₃ zvinowedzera zvakanyanya maitiro eozonation, zvichikurumidza kuparadza tsvina inoramba iripo, kusanganisira mishonga inosara mumvura yakasviba, kupfuura kugona kweozonation chete.
Tekinoroji yeMembrane: Kuisa mesoporous γ-alumina nanoparticles muma thin-film nanofiltration (TFN) membranes kwakachinja kubvisa munyu mumvura ine brackish. Ma membrane aya akagadziriswa ane kuwedzera katatu kwemvura uku achiramba achiramba munyu zvakanyanya (kusvika 98.4%), zvichiita kuti ashande zvakanaka pakunyorovesa nekuchenesa mvura.
Zvakanakira uye Kugara Kwenguva Refu
Chinhu chikuru chine alumina ndechekuti inogara kwenguva refu. Kusiyana nemafirita akawanda anoshandiswa kamwe chete, alumina inoshanda inogona kugadziriswazve. Kana yasvika pakukwanisa kwayo kunyudzwa, inogona kucheneswa nemakemikari uye kushandiswazve kwenguva dzakawanda, zvichideredza zvakanyanya mari yekushandisa uye marara ezvakatipoteredza. Kugadzikana kwayo nemakemikari, simba rayo remuchina, uye kuramba kwayo kukweshwa zvinoita kuti igare kwenguva refu munzvimbo dzinoda kurapwa.
Kutarisa Mberi
Sezvo nyika iri kurwisana nematambudziko emvura akaomarara, basa realumina rava kuda kuwedzera. Kutsvagurudza kuri kuenderera mberi pamusoro pezvinhu zvealumina zvakagadziriswa pamusoro uye zvakasanganiswa kuri kuramba kuchienderera mberi nekushanda zvakanaka, kuchitarisa zvinhu zvinosvibisa zviri kubuda nekunyatsojeka uye kugona. Kubva pakuchengetedza hutano hweveruzhinji kubva kufluoride nearsenic kusvika pakugonesa chizvarwa chinotevera chekubvisa munyu mumvura uye kushandisazve matekinoroji, alumina inoramba iri gamba risingakoshi uye riri kuchinja mukutsvaga kwepasi rose mvura yakachena uye yakachengeteka kune wese munhu.
