Nyob rau hauv niaj hnub hydrogen peroxide ntau lawm, ntau yam ntawm lwm yam adsorbents -xws li silica gel, molecular sieves, thiab activated carbon- kuj muaj nyob rau hauv lub khw rau siv nyob rau hauv cov txheej txheem zoo sib xws. Daim ntawv no nthuav qhia kev sib piv kev txheeb xyuas ntawmactivated alumina sivpiv rau cov adsorbents no, tshuaj xyuas lawv hla peb qhov tseem ceeb: kev ua haujlwm, kev siv, thiab tus nqi, nrog rau lub hom phiaj ntawm kev pab cov lag luam hauv kev xaiv cov khoom tsim nyog tshaj plaws.
1. Adsorption Capacity thiab Selectivity
· Activated Alumina
o Qhov zoo: Muaj peev xwm adsorption siab rau ya raws, impurities, thiab kab hlau ions; zoo txhim khu H₂O₂ purity.
o Cov yam ntxwv: Cov yam ntxwv ntawm qhov sib txawv ntawm qhov pore loj, nthuav tawm tsis kam rau cov kua qaub thiab alkali corrosion, thiab tsim nyog rau qhov kub siab - ib puag ncig.
· Molecular Sieves
o Qhov Zoo: Cov yam ntxwv los ntawm qhov tseeb qhov pore qhov ntau thiab tsawg, tso cai rau kev xaiv adsorption ntawm cov molecules tshwj xeeb (xws li, noo noo).
o Kev txwv tsis pub muaj peev xwm adsorption rau kab impurities hauv H₂O₂; nquag mus rau passivation thaum siv ntev.
· Silica Gel
o Qhov zoo: Tus nqi qis; nthuav tawm cov khoom zoo hygroscopic.
o Cov kev txwv: lub peev xwm adsorption qis dua li ntawm activated alumina; nyhav dhau los me ntsis kev cuam tshuam nrog H₂O₂, yog li txo kev ruaj ntseg.
· Cov pa roj carbon activated
o Qhov Zoo: Muaj peev xwm tshem tawm cov organic impurities thiab tsw.
o Cov kev txwv: nthuav tawm cov kev xaiv tsis zoo rau cov dej noo thiab cov hlau ions; Yog li ntawd, nws tsis tsim nyog rau thawj theem ntawm lub cev qhuav dej ntawm H₂O₂ ua.
2. Tshuaj stability thiab durability
· Activated alumina yog ruaj khov nyob rau hauv muaj zog oxidizing ib puag ncig thiab tsis yooj yim rau decompose los yog tsim cov tshuaj tiv thaiv sab.
· Silica gel thiab molecular sieves tej zaum yuav ib nrab hydrolyzed nyob rau hauv siab concentration ntawm H₂O₂, txo lawv cov kev pab cuam lub neej.
· Cov pa roj carbon monoxide tau yooj yim oxidized, ua rau muaj peev xwm txo qis sai.
3. Kev tsim dua tshiab thiab kev pabcuam lub neej
· Activated alumina: Nws tuaj yeem rov tsim dua los ntawm cua sov lossis chav, thiab muaj kev ua haujlwm zoo.
· Molecular sieve: Regeneration tej yam kev mob hnyav thiab yuav tsum tau nruj kub thiab siab tswj.
· Silica gel: regenerates sai sai tab sis muaj tsawg tus naj npawb ntawm reuses.
· Cov pa roj carbon activated: nyuaj rau rov tsim dua thiab yuav tsum tau hloov tsis tu ncua.
