Muaj zog acidic cationic resin yog ib qho kev siv ion pauv nruab nrab uas muaj zog acidic zog. Txawm li cas los xij, hauv qee qhov tshwj xeeb daim ntawv thov, nws yog ib qho tsim nyog los txo cov acidic cationic resin muaj zog los kho nws cov khoom qub. Hauv qab no yog ib qho kev qhia txog kev txo qis ntawm cov acidic cationic resins feem ntau.
Txo cov kauj ruam ntawm muaj zog acidic cationic resin:
1. Ntxuav: Ua ntej, tshem tawm cov khoom siv muaj zog acidic cationic resin los ntawm cov khoom siv thiab ntxuav nws nrog dej kom tshem tawm cov impurities thiab tshem tawm cov khoom tawm ntawm qhov chaw.
2. Kev ntxuav kua qaub: Muab cov tshuaj ntxuav hauv cov kua qaub (feem ntau yog siv hydrochloric acid lossis sulfuric acid). Kev ntxuav cov kua qaub yog qhov zoo rau kev tshem tawm cov hlau ions thiab lwm cov pa phem uas txuas nrog rau cov cob.
3. Kev txo qis: Tom ntej no, siv tus neeg sawv cev txo kom tshem tawm cov adsorbed cations los ntawm cov resin. Cov tshuaj txo qis xws li sodium hydroxide (NaOH) lossis hydrochloric acid (HCl). Cov neeg ua haujlwm txo qis no tuaj yeem pauv cov adsorbed cations nrog cov nquag hydrogen ions ntawm cov cob, ua kom nws rov qab tau nws cov peev xwm pauv ion.
4. Yaug: Tom qab txo qis, yaug cov resin kom huv si nrog dej txaus kom tshem tawm cov residual txo cov neeg ua hauj lwm thiab lwm yam impurities.
5. Sib npaug: Thaum kawg, muab cov khoom txo qis rau hauv dej kom rov qab mus rau lub xeev nruab nrab thiab npaj rau kev xa rov qab.
Kev txo cov nyhuv ntawm muaj zog acidic cationic resin
Cov txheej txheem txo qis ntawm cov kua qaub cationic resins cuam tshuam nrog kev nthuav tawm cov resin rau tus neeg sawv cev txo qis (feem ntau yog sodium hydroxide lossis hydrochloric acid) thiab pauv cov adsorbed cations nrog cov nquag hydrogen ions ntawm cov resin los ntawm cov tshuaj tiv thaiv. Nyob rau hauv txoj kev no, cov laus ions txuas nrog cov resin yuav raug tso tawm, thiab cov chaw nquag ntawm cov resin yuav maj mam rov qab mus rau lawv lub xeev siv tau.
Lub zog acidic cationic resin tom qab txo qis tuaj yeem xa rov qab siv, txuas ntxiv mus rau adsorb thiab pauv cov cations tshiab. Cov txheej txheem no txuas ntxiv kev pab cuam lub neej ntawm cov resin, yog li txuag cov nqi thiab ua kom muaj kev ua haujlwm tsis tu ncua thiab ua haujlwm zoo ntawm cov khoom siv. Hauv kev siv xws li kev kho dej, kev sib pauv ion, thiab lwm yam ion xaiv adsorption, kev txo qis yog ib kauj ruam tseem ceeb hauv kev tswj cov resin kev ua tau zoo thiab kev ua haujlwm zoo.
Hauv cov ntsiab lus, kev txo qis acidic cationic resins yog cov txheej txheem ntawm cov tshuaj tiv thaiv uas siv cov tshuaj txo qis los hloov cov acidic pawg hauv cov cob rau hauv cov ntsev thiab tso cov roj hydrogen. Cov txheej txheem no tuaj yeem rov kho cov resin rau nws lub xeev qub thiab kho nws cov kua qaub thiab ion pauv peev xwm. Daim ntawv thov ntawm txoj kev no tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm thaj chaw tshwj xeeb rau cov kua qaub tshaj tawm, thaum tseem tshem tawm cov ntawv txuas rau saum npoo ntawm cov resin thiab txhim kho nws lub neej kev pab cuam.
