Dab tsi yog qhov tseem ceeb ntawm iodine tus nqi ntawm actived carbon?

Iodine tus nqi yog tus nqi ntawm iodine tshuav nyiaj tau zoo uas yog ntau tshaj tawm nyob rau saum npoo ntawm actived carbon. Nov yog txoj kev xeem.
Nyob rau hauv kev tshaj tawm txoj kev xav, cov lwg me me ntawm cov sib txawv / cov qib sib txawv yuav nqus cov kev coj lub cev sib piv rau ntawm lub zog sib txawv. Chemists ntsuas thiab sim los adsorption nyob rau hauv cov kev sib xws hauv txoj kev zoo sib xws. Vim tias iOdine yog qhov me me heev, nws tuaj yeem qhia tau zoo tias muaj cov pa roj carbon kom muaj cov pa roj av loj / loj -density pores. Iodine tus nqi sib haum rau iodine tshuav nyiaj muaj peev xwm ntawm cov roj carbon ua huaj. Tus naj npawb ntawm adsorption iodine muaj feem xyuam rau lub pore degree nce hauv cov carbon ua haujlwm, thiab yog siv los ua kev ua haujlwm dav dav.
Iodine tus nqi yog dab tsi?
Vim nws yooj yim sim ntawm qhov zoo ntawm adsorption tus neeg sawv cev, iodine tus nqi yog ib feem siv dav rau kev kuaj cov pa roj carbon. Nws muab tus nqi kwv yees rau nws thaj chaw thiab tus nqi sib nyiam. Raws li cov ASTM D46 {{0}}}}}}}}}. 02n (0.21)
Yuav ntsuas li cas?
V siv 1 {{{{4 4}} ml 5% (v / v) hcl los daws cov qauv. Boil qhov sib tov rau 3 {{0}} vib nas this thiab tom qab ntawd txias ntawm chav tsev kub. Ntxiv 1 {0 {13}}} ml {} {16}}. 1n iodine tov rau qhov sib xyaw thiab do rau 30 vib nas this. Tom qab ntawd lim cov tshuaj, siv 0.1n (0.05Mol l -1}}}}}}}}}}}}}}}}} Tus nqi ntawm iodine adsorbed ib gram ntawm adsorbent adsorption yog piv rau cov seem iodine concentration. Yog tias cov nyiaj nruab nrab ntawm iodine concentration tsis yog nyob rau hauv thaj tsam ntawm (0. 008-0. 04n), cov txheej txheem ntawm kev siv cov pa roj carbon monox zoo rau txhua qhov sib npaug. Kev tsom xam ntawm peb lub ntsiab lus, kev suav ntawm iodine tus nqi yog tus nqi adsorption thaum iodine concentration yog 0.02n.
