Qhov sib txawv tseem ceeb ntawm cation txauv peev thiab anion txauv peev xwm yog qhov sib pauv cation muaj peev xwm qhia tau tias muaj pes tsawg tus nqi tsis zoo muaj los nyiam cations, whereas anion pauv peev xwm qhia tau hais tias tus nqi zoo uas muaj los nyiam cov anions hauv kev daws teeb meem.
Resins yog cov khoom tseem ceeb hauv kev tshuaj ntsuam chemistry. Muaj ob hom resins li cationic resins thiab anionic resins. Cov no yog ob feem ntau cov resins uas muaj txiaj ntsig zoo hauv kev sib pauv ion. Raws li, peb tuaj yeem sau npe cov txheej txheem uas muaj cov khoom no ua cation txauv lossis anion txauv txheej txheem.
Cation Exchange Capacity yog dab tsi?
Cation pauv peev xwm tuaj yeem txhais tau tias yog qhov ntsuas ntawm cov cations uas tuaj yeem khaws cia rau ntawm cov av particle. Feem ntau, tsis zoo them atoms lossis molecules ntawm cov av saum npoo tuaj yeem sib txuas nrog cov atoms lossis cov molecules zoo, tso cai rau kev sib pauv ntawm cov ions no nrog lwm cov khoom zoo hauv cov dej hauv av uas nyob ib puag ncig cov av.
Daim duab 01: Qhov cuam tshuam ntawm av pH ntawm Cation Exchange Capacity
Kev sib pauv cation yog ib txoj hauv kev los ntawm cov khoom siv hauv cov av tuaj yeem hloov cov chemistry ntawm cov av. Nws tuaj yeem cuam tshuam ntau yam ntawm av chemistry. Ntxiv mus, peb tuaj yeem siv nws los ntsuas qhov av fertility. Qhov no yog vim hais tias nws tuaj yeem qhia lub peev xwm ntawm cov av kom khaws tau ntau cov as-ham hauv cov nroj tsuag-muaj daim ntawv. Tsis tas li ntawd, kev sib pauv cation muaj peev xwm qhia tau tias muaj peev xwm ntawm cov av kom khaws cov pa phem cations xws li txhuas cations.
Yeej, qhov sib pauv cation muaj peev xwm yog tus nqi zoo uas tau txais kev sib pauv ib pawg ntawm cov av. Nws tshwm sim los ntawm ntau yam kev tsis zoo nyob rau hauv cov av particle nto xws li av nplaum minerals thiab av organic teeb meem. Ntxiv mus, av pH tuaj yeem cuam tshuam qhov kev sib pauv cation ntawm cov av.
Anion Exchange Capacity yog dab tsi?
Anion pauv peev xwm yog tus lej ntawm cov nqi tsis zoo uas tau khaws cia los ntawm 100 grams av. Peb tuaj yeem nthuav qhia tus nqi no li 100 grams av. Nws muab tag nrho cov anions pauv uas cov av tuaj yeem nqus tau. Tsis tas li ntawd, tag nrho cov av av nplaum thiab cov organic teeb meem muaj qhov sib piv me me ntawm qhov chaw zoo uas tuaj yeem khaws cov anions nyob rau hauv dynamic equilibrium nrog rau cov av tov. Lub peev xwm pauv anion tuaj yeem raug sau ua AEC. Lub peev xwm pauv ion ntawm ib qho av yog siab dua thaum lub peev xwm pauv cation yog siab.
Qhov txawv ntawm Cation Exchange Peev thiab Anion Exchange Peev yog dab tsi?
Cation pauv peev xwm yog qhov ntsuas ntawm tus lej ntawm cations uas tuaj yeem khaws cia ntawm cov av particle. Anion pauv peev xwm, ntawm qhov tod tes, yog tus naj npawb ntawm cov nqi tsis zoo uas tau khaws cia los ntawm 100 grams av. Qhov sib txawv tseem ceeb ntawm cation exchange peev thiab anion pauv peev xwm yog tias cation pauv peev xwm qhia tau hais tias muaj pes tsawg tus nqi tsis zoo muaj los nyiam cations, whereas anion pauv peev xwm qhia tau hais tias tus nqi zoo uas muaj los nyiam anions hauv kev daws.
Cov hauv qab no qhia txog qhov sib txawv ntawm cation pauv peev xwm thiab anion pauv peev xwm hauv daim ntawv teev npe rau ib sab ntawm kev sib piv.
Summary – Cation Exchange Capacity vs Anion Exchange Capacity
Qhov sib txawv tseem ceeb ntawm cation txauv peev thiab anion txauv peev xwm yog qhov sib pauv cation muaj peev xwm qhia tau tias muaj pes tsawg tus nqi tsis zoo muaj los nyiam cations, whereas anion pauv peev xwm qhia tau hais tias tus nqi zoo uas muaj los nyiam anions hauv kev daws.
