Porous adsorbent Properties!

Porous abu adsorbent ne m abu wanda zai iya yadda ya kamata adsorb wasu aka gyara daga gas ko ruwa, wanda da manyan takamaiman surface area, dace pore tsarin da surface tsarin, da kuma karfi adsorption iya aiki ga adsorbates.Adsorbents kullum ba su sha sinadaran halayen tare da adsorbates da matsakaici. , yin su dace don kerawa da sauƙin sake farfadowa.Suna da kyawawan kayan talla da kayan aikin injiniya.

Ƙarfin adsorption na adsorbent ya fito ne daga porosity da kuma yawan adadin wuraren tallan tallace-tallace da aka samar ta hanyar babban yanki na musamman.Lokacin da duk wuraren da ke aiki a cikin adsorbent suna mamaye, ƙarfin tallan sa ya kai ga cikawa.Idan adsorbate ya mamaye wuraren aiki, wannan tsari yana canzawa kuma ana kiran saturation adsorbent.Yana buƙatar dumama, damuwa, da sauran hanyoyin sabuntawa don dawo da aikin tallan tallan da aka rigaya ya cika;Idan abun da ke mamaye wurin tallan ba shine adsorbate ba, amma sauran abubuwan da ke da wahalar cirewa daga wurin talla, tallan ba zai yuwu ba kuma ba za a iya sake amfani da adsorbent ba.Ana kiran wannan al'amari gubar adsorbent.
