Yuav ua li cas npaj siab adsorbent nrog micro silicon hmoov? Cov nyhuv adsorption ntawm micro-silica hmoov tuaj yeem ua tau zoo los ntawm nws qhov loj me me. MCM-41 mesoporous molecular sieve nrog pore loj xws li 2 nm mus rau 5nm tuaj yeem tsim los ntawm cov hmoov purified micro-silica thiab siv los ua adsorbent kom tiav cov adsorption ntawm hnyav hlau ions. High purity micro-silica hmoov (95% ~ 98%, wt) tom qab acid leaching. Los ntawm kev ntxiv cov tshuaj sodium hydroxide thiab cov qauv qhia tus neeg sawv cev rau mesoporous silica molecular sieve, cov txheej txheem ntawm cov hlau hnyav hnyav adsorption tau ua tiav cov txiaj ntsig zoo, thiab cov nqi ntxiv ntawm micro-silica hmoov tau nce zoo heev. Lub hydrophobic silica gel synthesized los ntawm sol-gel txoj kev siv iav dej raws li silicon qhov chaw plays lub luag haujlwm tseem ceeb hauv cov roj thiab cov roj rov qab, thiab nws cov khoom adsorption thiab desorption zoo dua li cov adsorbents zoo tib yam. Cov khoom siv lithium silicate adsorption ua los ntawm lithium carbonate thiab micro-silicon hmoov thiab calcined los ntawm cov khoom kub kub txheej txheem raws li molar ratio ntawm 1.94 tau ua lub luag haujlwm zoo hauv kev kho cov pa roj carbon dioxide hauv cov cua.
