Nrog rau kev loj hlob sai ntawm kev lag luam thiab hauv nroog, dej muaj kuab paug tau ua rau tib neeg fluorful, thiab cov tshuaj tua tsiaj, thiab cov tshuaj ecological,Qhib Aluminatau dhau los ua ib qho ntawm cov ntaub ntawv tseem ceeb hauv kev kho cov dej ua haujlwm vim nws qhov kev ua tiav zoo tshaj plaws, tshuaj lom neeg ruaj khov, thiab kev lag luam .
Cov yam ntxwv ntawm activated alumina rau kev kho dej
Thaj chaw tshwj xeeb thaj chaw: muab ntau cov chaw tshaj tawm adsorption .
Cov qauv ntxeem tau: micropores thiab mesopores tau faib, haum rau kev kos duab ntawm cov kab sib txawv ntawm qhov sib txawv .
Tshuaj lom neeg stability: acid thiab alkali resistant, haum rau ntau yam dej ntws .
Xaiv Adsorption: muaj kev muaj zog muaj zog rau cov tshuaj paug tshuaj xws li tshuaj fluoride, arsenic, thiab phosphate .
Lo lus rov qab lees paub: Adsorption muaj peev xwm tuaj yeem rov qab los ntawm cua sov lossis tshuaj ntxuav .
Daim ntawv thov ntawm actument alumina hauv kev kho dej
1.} Kev Kho Dej Haus Dej
(1) Tshem tawm fluoride
Cov tshuaj fluoride yog ib txoj kab kev tseem ceeb rau tib neeg lub cev, tab sis muaj kev sib pauv fluoride thiab muaj txiaj ntsig zoo rau cov tshuaj fluoride thiab cov kab mob sab nrauv thiab cov kab mob, thiab cov pob txha tsis zoo, thiab yog cov tshuaj tua kab mob fluoride
(2) arsenic tshem tawm
Arsenic yog cov kuab paug zoo heev . Ua kom tau zoo rau cov arsenite tsis muaj zog rau kev hloov pauv li (v) los nce cov nqi tshem tawm .
{{0 {}} kev kho kom muaj dej khiav ceev
• Tshuaj Txom Nyem: Siv rau kev kho mob phosphate hauv kev lag luam xws li cov electroplating thiab chiv kom tiv thaiv tau dej lub cev .
• Hnyav hlau Adsorption: tuaj yeem tshem cov hlau cov kab tsuag xws li txhuas, cadmium, thiab chromium.
• organic kuab paug: qee cov alumina kuj muaj qee yam muaj peev xwm adsorption rau cov organic xws li dyes thiab phenols .
3.} lwm yam kev siv
• Desiccant: Siv lub cev qhuav dej los yog kua .
• Cov cab kuj catalyst: siv los txhawb catalysts hauv kev lag luam tshuaj lom neeg {}}}
Adsorption mechanism ntawm kev ua kom Alumina
Adsorption txheej txheem ntawmQhib AluminaFeem ntau yog nyob ntawm cov txheej txheem hauv qab no:
1. npoo hydroxyl txauv: acions hauv dej (xws li pab pawg ntawm cov pawg ntawm alumina.
2.} Electrostatic advertatic advertatic adventatatic them thiab tuaj yeem adsorb tsis zoo them ions.
3.} Cov duab kos npe tawm: lwg
