Vim li cas cov graphite nthuav dav thiaj li nqus tau cov roj xws li cov roj hnyav

Cov graphite nthuav dav yog ib qho adsorbent zoo heev, tshwj xeeb tshaj yog nws muaj cov qauv xoob thiab muaj peev xwm adsorption muaj zog rau cov organic compounds. 1g ntawm cov graphite nthuav dav tuaj yeem nqus tau 80g ntawm cov roj, yog li cov graphite nthuav dav yog tsim los ua ntau yam roj kev lag luam thiab cov roj kev lag luam. adsorbent. Cov kws kho graphite Furuite hauv qab no qhia txog kev tshawb fawb txog kev adsorption ntawm cov roj xws li cov roj hnyav los ntawm cov graphite nthuav dav:

1. Cov graphite uas nthuav dav yog siv los ua hom adsorbent tshiab vim muaj ntau lub qhov hws ntawm qhov chaw tshuaj ntsuam.

Cov kab graphite nthuav dav sib txuas ua ke, tsim ntau qhov hws saum npoo, uas yog qhov zoo rau kev nqus cov tshuaj macromolecular, qhia txog lub peev xwm nqus loj, uas tuaj yeem daws qhov teeb meem ntawm roj thiab cov tshuaj organic tsis-polar.

2. Cov graphite nthuav dav yog siv los ua hom adsorbent tshiab vim yog lub mesh loj sab hauv

Txawv ntawm cov adsorbents ntawm lwm cov ntaub ntawv, cov molecules sab hauv ntawm cov graphite nthuav dav feem ntau yog qhov nruab nrab thiab loj pores, thiab feem ntau ntawm lawv nyob rau hauv ib lub xeev txuas nrog, thiab kev sib txuas network ntawm lamellae zoo dua. Nws muaj cov nyhuv zoo heev rau kev nqus cov organic macromolecules ntawm cov roj hnyav no. Cov roj hnyav molecules yooj yim nkag mus thiab diffuse sai sai hauv lawv lub network kom txog thaum lawv sau cov qhov sib txuas sab hauv. Yog li ntawd, cov nyhuv adsorption ntawm cov graphite nthuav dav zoo dua.

Vim yog cov qauv xoob thiab qhov ntxeem tau ntawm cov graphite nthuav dav, lawv muaj cov nyhuv adsorption zoo rau qee qhov roj av thiab roj av, uas ua rau nws siv dav hauv kev tiv thaiv ib puag ncig.
