Vaivai vaivai anion fesuiaʻi resin

Vaivai vaivai anion fesuiaʻi resin

Vaivai Faʻavae Anion (WBA) resins o polymer faia e polymerizing styrene pe acrylic acid ma divinylbenzene ma chlorination,faʻaputuga Kamupani Dongli mafai maua ai gel ma macroporous ituaiga WBA resini ma isi koluse. O la matou WBA o loʻo avanoa i le tele o faʻailoga e aofia ai Cl form, toniga tele ma vasega o meaʻai.

GA313, MA301, MA301G, MA313

Vaivai vaivai anion fesuiaʻi resin: o lenei ituaiga o resin o loʻo iai ni vaega vaivai, pei o le muamua vaega amino (e taʻua foi o le vaega muamua amino) - NH2, lona lua amino vaega (lona lua vaega amino) - NHR, po o le tertiary vaega amino (tertiary vaega amino ) - NR2. E mafai ona latou faʻateʻa Au - i le vai ma e vaivai lava faʻavae. I le tele o tulaga, o le resin adsorbs le atoa isi acid mole i le tali. E faʻatoa mafai ona galue i lalo ole solituli poʻo acidic tulaga (pei ole pH 1-9). E mafai ona toe faʻafouina ma Na2CO3 ma NH4OH.

Aveesea le mama
O oloa gaosi o le ion exchange resin e masani ona iai se vaega laʻititi o le maualalo o le polymer ma le reactive monomer, faʻapena foi ma le inorganic impurities e pei o le iron, lead and copper. A o le resin e faʻafesoʻotaʻi ma vai, acid, alkali poʻo isi tali, o mea i luga o le a fesiitaʻi i totonu o le tali, e aʻafia ai le lelei o le suavai maua. O le mea lea, o le resin fou e tatau ona faia muamua ae leʻi faʻaaogaina. E masani lava, vai e faʻaaogaina e faʻaaoga ai le resin faʻalauteleina uma, ona faʻapea ai lea, O mea le aoga i totonu o le tino (e tele lava o vaega o le uʻamea) e mafai ona aveʻese e le 4-5% dilute hydrochloric acid, ma e mafai ona aveʻesea le faʻaletino e le 2-4% dilute sodium hydroxide tali Afai e faʻaaogaina i vailaʻau sauniuniga, e tatau ona faʻasusu i le ethanol.

Togafitiga Faʻaleleia Faʻavaitaimi Periodic
I le faʻaogaina o le resin, e manaʻomia le puipuia o le fesoʻotaʻiga ma le suauʻu faʻaleagaina, meaola mole microorganism, malosi oxidant ma isi metala (pei o le uʻamea, 'apamemea, ma isi) ina ia aloese ai mai le faʻaititia o le ion exchange mafai poʻo le leiloa foʻi galuega. O le mea lea, o le resin tatau ona faʻagaoioia e le tusa ai ma le tulaga. O le faʻagaoioia metotia mafai ona fuafuaina e tusa ai ma le faʻaleagaina tulaga ma tulaga. O le mea e masani ai, o le cation resin e faigofie ona faʻaleagaina e Fe i le faʻamaluluina e le faʻatofuina o le hydrochloric acid, Ona faʻasusu malie ai lea, o le anion resin e faigofie ona faʻafefiloi e mea masani. E mafai ona faʻasusu pe fufuluina i le 10% NaCl + 2-5% NaOH fefiloi fofo. Afai e tatau ai, e mafai ona faʻasusu i le 1% hydrogen peroxide solution mo ni nai minute. Isi, mafai foi ona faʻaaoga acid-base alternate togafitiga, faʻamamaina togafitiga, 'ava malosi togafitiga ma eseese faʻamamaina metotia.

Fou Resin Pretreatment
Fouina o le resin fou: i oloa gaosi oloa o ion fesuiaʻi resin, e i ai le laititi aofaʻi o oligomers ma monomers e le auai i le tali atu, ma o loʻo iai foʻi inorganic impurities e pei o uʻamea, taʻitaʻi ma apamemea. A o le resin faʻafesoʻotaʻi vai, acid, alkali poʻo isi tali, o mea i luga o le a fesiitai atu i le fofo, lea o le a aʻafia ai le lelei o le effluent. O le mea lea, o le resin fou e tatau ona muamua togafitia ao le i faʻaaogaina. E masani lava, o le resin o le a faʻalauteleina ma le vai, ma ona o le inorganic impurities (tele uʻamea faʻatulagaina) mafai ona aveʻese e 4-5% dilute hydrochloric acid, ma le faʻaletino impurities mafai ona aveʻese e 2-4% dilute sodium hydroxide fofo e mulumulu latalata i le solitu.
