Ekicweka kya kaboni ekikozirwe

Omutwarize gw’okutwara amaizi ogwa activated carbon niguruga omu nkora yaayo ey’ebicupuri etunguukire munonga. Okushwijuma kwa X-ray diffraction nikworeka ngu omwanya gw’ahaiguru ogw’omutindo gw’ahaiguru ogw’okukoresa kaboni nigubaasa kuhika ahari 1,000-3,000m2/g, harimu obucweka obukye oburimu oburaingwa bwa 0.8-2nm, obucweka obukye oburimu oburaingwa bwa 2-50nm, n’obucweka obuhango oburimu oburaingwa oburikurenga 50n. Omuringo ogu gw’ebicupuri ogw’emitendekyere mingi nigubaasa kuguma gye n’ebintu ebiine amagara, chlorine esigaireho n’ebyoma ebimwe ebiremeire ebiine oburemeezi bwa molecule bwa daltons 60-300 kurabira omu kukwatanisa kw’amaani ga van der Waals n’okuteerana kw’eby’obuhangwa. Namunonga omu kujanjaba ebirungo by’ebihangirwe ebirikuhindukahinduka (VOCs), obushoboorozi bw’okutwara ebintu ebirikushiisha nk’ebirikwetwa benzene na formaldehyde nibubaasa kuhika ahari 200-500mg/g.

Ebishwijumwa bya kaboni eby’omurembe ogu bikozirwe n’omutindo gw’ebintu bingi ebirimu ekicweka ky’okubanza ky’okukyebera (PP cotton), ekicweka ky’okukyebera ekikuru (kaboni erikukora ey’obujuma/obucupa), n’ekicweka ky’okukyebera bwanyima y’okukyebera (ekirungo ky’okurwanisa obukooko). Ebicweka by‘omutindo gw‘amakorero nibikira kutwara enkora y‘okugyendera omu nkora y‘okutambura kw‘omubiri, kugira ngu obwire bw‘okukoragana kw‘eby‘amakuru kurabira omu kitanda kya 0.5-2mm activated carbon bugume aha sekondi 5-15, kandi okugwa kwa pressure nikutegyekwa ahari 0.05-0.2 MPa. Okushohoza kw’eby’obuhangwa kw’ebintu ebitari bimwe na bimwe ebirikushiisha (nk’eky’okureeberaho, hydrogen sulphide, mercury vapour) nikubaasa kwongyerwamu amaani ahabw’okukoresa tekinologiya y’okuhindura aha itaka (nk’okutaho ebiriisa by’ekyoma ebirikuhinduka), kandi okushohoza okutoorainwe nikubaasa kwongyerwaho n’ebicweka 40 ahari igana.
