Lebitso la bethe e tsoakiloeng le kenyelletsa lehoakhoa le matla la phapanyetsano ea asiti le resin ea phapanyetsano e matla ea anion.
Mosebetsi oa Mixed Bed Resin
Deionization (kapa demineralization) e bolela feela ho tlosa li-ion. Ions li lefisoa liathomo kapa limolek'hule tse fumanoang ka metsing ka litefiso tse mpe kapa tse ntle. Bakeng sa lits'ebetso tse ngata tse sebelisang metsi joalo ka sesebelisoa sa ho hlatsoa kapa lisebelisoa, li-ion tsena li nkuoa e le litšila mme li tlameha ho tlosoa ka metsing.
Li-ion tse lefisitsoeng hantle li bitsoa li-cation, 'me li-ion tse lefisitsoeng hampe li bitsoa anion. Ion phapanyetsano ea li-resin li fapanyetsana li-cations le li-anion tse sa batleheng ka hydrogen le hydroxyl ho theha metsi a hloekileng (H2O), e seng ion. Se latelang ke lenane la li-ion tse tloaelehileng metsing a masepala.
Molao-motheo oa ho Sebetsa oa Resin Bed Resin
Li-resin tsa bethe tse tsoakiloeng li sebelisoa ho hlahisa metsi a nang le deionized (demineralized kapa "Di"). Li-resin tsena ke lifaha tse nyane tsa polasetiki tse entsoeng ka liketane tsa polima tse nang le lihlopha tse sebetsang tse kenelletseng lifaheng. Sehlopha se seng le se seng se sebetsang se na le tefiso e tsitsitseng kapa e mpe.
Li-resin tsa Cationic li na le lihlopha tse mpe tse sebetsang, ka hona li hohela li-ion tse nang le litefiso tse ntle. Ho na le mefuta e 'meli ea li-resin tsa cation, e fokolang acid cation (WAC) le acid e matla ea cation (SAC). Phofo ea cation ea acid e fokola e sebelisoa haholo bakeng sa dealkalization le lits'ebetso tse ling tse ikhethang. Ka hona, re tla tsepamisa maikutlo ho karolo ea lehoakhoa le matla la asiti le sebelisoang ha ho etsoa metsi a hloekisitsoeng.
Li-resin tsa Anionic li na le lihlopha tse ntle tse sebetsang 'me ka hona li hohela li-ion tse lefelloeng hampe. Ho na le mefuta e 'meli ea li-resin tsa anion; Anion ea fokolang (WBA) le anion base e matla (SBA). Mefuta ka bobeli ea li-resin tsa anionic e sebelisoa ho hlahiseng metsi a nontšitsoeng, empa a na le litšobotsi tse latelang tse fapaneng:
Ha e sebelisoa tsamaisong ea bethe e tsoakiloeng, WBA resin e ke ke ea tlosa silika, CO2 kapa e na le bokhoni ba ho fokotsa li-acid tse fokolang, 'me e na le pH e tlase ho feta ho se nke lehlakore.
Resin ea bethe e tsoakiloeng e tlosa li-anion tsohle tafoleng e kaholimo, ho kenyeletsoa le CO2, 'me e na le pH e phahameng ho feta ho se nke lehlakore ha e sebelisoa tsamaisong e ikemetseng ea libethe ka lebaka la ho dutla ha sodium.
Li-Resin tsa Sac le SBA li sebelisoa betheng e tsoakaneng.
Bakeng sa ho hlahisa metsi a hloekisitsoeng, resin ea cation e nchafatsoa ka hydrochloric acid (HCl). Hydrogen (H +) e lefisoa hantle, ka hona e itšoarella ho lifaha tsa cationic resin tse mpe. Resin ea anion e ile ea nchafatsoa le NaOH. Lihlopha tsa Hydroxyl (OH -) li qosoa ka mokhoa o fosahetseng 'me li ikamahanya le lifaha tse nang le lehoakhoa la anionic.
Li-ion tse fapaneng li hoheloa ke lifaha tsa lehoakhoa tse nang le matla a fapaneng. Mohlala, calcium e hohela lifaha tsa cationic resin ka matla ho feta sodium. Haedrojene e hodima difaha tsa cationic resin le hydroxyl hodima difaha tsa anionic resin ha di na kgohedi e matla difaheng. Ke ka lebaka lena phapanyetsano ea ion e lumelloang. Ha cation e nang le litefiso tse ntle e phalla ka har'a lifaha tsa cationic resin, phapanyetsano ea cation ke hydrogen (H +). Ka mokhoa o ts'oanang, ha anion e nang le tefiso e mpe e phalla ka har'a lifaha tsa anion resin, anion e fapanyetsana le hydroxyl (OH -). Ha o kopanya hydrogen (H +) le hydroxyl (OH -), o theha H2O e hloekileng.
Kamora nako, libaka tsohle tsa phapanyetsano ea li-cation le lifaha tsa anion resin lia sebelisoa, 'me tanka ha e sa hlahisa metsi a nang le deionized. Hona joale, lifaha tsa lehoakhoa li hloka ho nchafatsoa hore li ka sebelisoa bocha.
Hobaneng u khetha lehoakhoa le tsoakiloeng ka bethe?
Ka hona, ho hlokahala bonyane mefuta e 'meli ea li-resin tsa phapanyetsano ea ion ho hlophisa metsi a ultrapure kalafong ea metsi. Lehoakhoa le le leng le tla tlosa li-ion tse lefisitsoeng hantle 'me le leng le tlose li-ion tse lefisitsoeng hampe.
Ka har'a bethe e tsoakiloeng, cationic resin e lula e le sebakeng sa pele. Ha metsi a masepala a kena ka tankeng e tlatsitsoeng ka lehoakhoa la cation, li-cation tsohle tse nang le tjhelete e ntle li hoheloa ke lifaha tsa lehoakhoa la cation ebe li fapanyetsana ka hydrogen. Li-anion tse nang le tefiso e mpe li ke ke tsa hoheloa ebe li feta har'a lifaha tsa cationic resin. Mohlala, ha re hlahlobe calcium chloride metsing a fepa. Ka tharollo, li-ion tsa khalsiamo li lefisoa hantle 'me li ikamahanya le lifaha tsa cationic ho lokolla li-ion tsa hydrogen. Chloride e na le tefiso e mpe, ka hona ha e ikamahanye le lifaha tsa cationic resin. Haedrojene e nang le tefo e ntle e itšoarella ka chloride ion ho etsa hydrochloric acid (HCl). Metsi a tsoang mokhoeng oa phallo a tla ba le pH e tlase haholo le ho ba le tšebetso e phahameng haholo ho feta metsi a kenang a fepa.
Mantle a cationic resin a entsoe ka asiti e matla le asiti e fokolang. Ebe metsi a asiti a tla kena ka tankeng e nang le lehoakhoa la anion. Li-resin tsa Anionic li tla hohela li-anion tse lefelloeng hampe tse kang li-chloride ions ebe li li fapanyetsana ka lihlopha tsa hydroxyl. Phello ke hydrogen (H +) le hydroxyl (OH -), e etsang H2O
Ebile, ka lebaka la "ho dutla ha sodium", sistimi e tsoakaneng ea bethe e ke ke ea hlahisa H2O ea 'nete. Haeba sodium e dutla ka tanka ea phapanyetsano ea cation, e kopana le hydroxyl ho theha sodium hydroxide, e nang le ts'ebetso e phahameng. Ho dutla ha sodium ho hlaha hobane sodium le haedrojene li hohela ka tsela e ts'oanang le lifaha tsa cationic resin, 'me ka linako tse ling li-ion tsa sodium ha li fapanyetsane li-ion tsa haedrojene ka botsona.
Ka har'a bethe e tsoakaneng, asiti e matla ea cation le resin e matla ea anion e kopane hammoho. Sena se thusa tanka e kopaneng ea bethe ho sebetsa joalo ka likete tsa libethe tse kopaneng ka tankeng. Phapanyetsano ea cation / anion e ne e phetoa betheng ea resin. Ka lebaka la palo e kholo ea phapanyetsano ea cation / anion e phetoang, bothata ba ho dutla ha sodium bo ile ba rarolloa. Ka ho sebelisa bethe e tsoakaneng, o ka hlahisa metsi a boleng bo holimo ka ho fetesisa.
