Muaj zog Acid Cation
Cov kua qaub sib pauv hloov pauv yog ib hom cation pauv pauv nrog cov pab pawg sulfonic acid (- SO3H) ua pawg sib pauv tseem ceeb, uas tuaj yeem rov siv tau.
Kev siv cov ntxhia ntxhia zoo tib yam yog tib yam. Hom ntawm cov dej muag muag yog cov kua qaub uas muaj zog pauv pauv. Cov tshuaj catalyst tshwj xeeb yuav tsum tau siv, vim nws tseem cuam tshuam nrog kev cuam tshuam ntawm hydrogen ion tso tawm tus nqi, pore loj thiab qib sib txuas ntawm cov tshuaj tiv thaiv.
Hauv daim ntawv thov kev lag luam, qhov zoo ntawm ion txauv cob yog qhov muaj peev xwm kho tau ntau, ntau qhov kev hloov xim, muaj peev xwm txo qis xim, tshem tawm ntau yam ions, rov tsim dua, rov ua haujlwm ntev thiab tus nqi lag luam qis (txawm hais tias tus nqi ntawm kev nqis peev ib zaug yog loj) . Ntau yam thev naus laus zis tshiab raws li kev sib pauv ion, xws li kev sib cais ntawm chromatographic, tshem tawm ion, electrodialysis, thiab lwm yam, muaj lawv tus kheej lub luag haujlwm tshwj xeeb thiab tuaj yeem ua haujlwm ntau yam tshwj xeeb, uas nyuaj rau ua los ntawm lwm txoj hauv kev. Txoj kev txhim kho thiab thov siv ion txauv thev naus laus zis tseem tab tom txhim kho sai.
Nco tseg
1. Ion txauv resin muaj qee qhov dej thiab yuav tsum tsis txhob muab tso rau hauv qhov cua qhib. Thaum lub sijhawm khaws khoom thiab thauj mus los, nws yuav tsum tau khaws kom ntub dej kom tsis txhob muaj huab cua qhuav thiab lub cev qhuav dej, ua rau cov pob zeb tawg. Yog tias cov kua dej tau qhuav thaum lub sijhawm khaws cia, nws yuav tsum tau tsau hauv cov dej qab ntsev (10%) thiab tom qab ntawd maj mam maj mam. Nws yuav tsum tsis txhob muab ncaj qha mus rau hauv dej kom tsis txhob nthuav dav sai thiab tawg ntawm cov tshuaj.
2. Thaum khaws cia thiab thauj mus los thaum lub caij ntuj no, qhov kub yuav tsum tau khaws cia ntawm 5-40 ℃ kom tsis txhob muaj cua txias lossis kub dhau, uas yuav cuam tshuam rau qhov zoo. Yog tias tsis muaj cov cuab yeej tiv thaiv cua sov nyob rau lub caij ntuj no, cov yas tuaj yeem khaws cia hauv cov dej ntsev, thiab cov dej qab ntsev tuaj yeem txiav txim siab raws li qhov ntsuas kub.
3. Cov khoom lag luam ntawm ion txauv resin feem ntau muaj cov khoom me me ntawm cov polymer qis thiab tsis muaj monomer reactive, nrog rau cov khoom tsis huv xws li hlau, txhuas thiab tooj liab. Thaum cov tshuaj sib txuas nrog dej, kua qaub, alkali lossis lwm yam kev daws teeb meem, cov tshuaj saum toj no yuav raug xa mus rau hauv kev daws teeb meem, cuam tshuam qhov zoo ntawm cov dej ntws. Yog li ntawd, cov tshuaj tshiab yuav tsum tau kho ua ntej siv. Feem ntau, cov tshuaj tau nthuav dav nrog dej, Tom qab ntawd cov tshuaj tsis huv (feem ntau yog cov hlau sib txuas) tuaj yeem tshem tawm los ntawm 4-5% dilute hydrochloric acid, thiab cov organic tsis huv tuaj yeem tshem tawm los ntawm 2-4% dilute sodium hydroxide tov. Yog tias nws tau siv hauv kev npaj tshuaj, nws yuav tsum tau so hauv ethanol.
