I-resin ye-acid cation exchange ebuthakathaka iyinhlobo ye-resin equkethe amaqembu e-asidi ashintshashintshayo: i-carboxyl COOH, i-phosphate po2h2 ne-phenol.
Isetshenziswa kakhulu ekwelapheni amanzi, ukuhlukaniswa kwezinto ezingavamile, ukususwa kwamakhasi nokuthambisa amanzi, ukukhipha nokwehlukanisa ama-antibiotic nama-amino acid embonini yezemithi.
Feamandla
(1) I-resin exchange cation exchange resin ebuthakathaka inezici ezifanayo emanzini. Ngakho-ke, amandla ayo okubola usawoti ongathathi hlangothi abuthakathaka (okusho ukuthi kunzima ukusabela ngosawoti bama-anion anamandla njenge-SO42 -, Cl -). Ingasebenza kuphela ngosawoti ababuthaka be-asidi (usawoti one-alkalinity) ukukhiqiza i-asidi ebuthakathaka esikhundleni se-asidi eqinile. Amanzi ane-alkalinity ephezulu angalashwa nge-resin ye-asidi eshisayo ye-acid resin exchange. Ngemuva kokuthi ama-cations ahambelana ne-alkalinity emanzini asuswe ngokuphelele, ama-cations ahambelana ne-acid eqinile emanzini angasuswa nge-resin eqinile ye-asidi H-exchange resin.
(2) Ngenxa yokuthi i-resin exchange cation exchange resin inobuthakathaka obuphezulu be-H +, kulula ukuyivuselela, ngakho-ke ingavuselelwa kabusha ngoketshezi oludoti lwe-resin eqinile ye-asidi H-type cation exchange resin.
(3) Umthamo wokushintshana we-resin ye-acid cation exchange resin mkhulu kunowenhlaka ye-acid cation exchange resin.
(4) I-resin ye-acid cation exchange ebuthakathaka ine-low crosslinking degree nama-pores amakhulu, ngakho-ke amandla ayo emishini angaphansi kunalawo anamandla e-acid cation exchange resin.
Ezinye Izici
Izici ze-resin exchange cation resin emanzini ebuthakathaka zifana nalezo ze-asidi ebuthakathaka. Inokuxhumana okubuthaka nosawoti ongathathi hlangothi (njenge-SO42 -, Cl - namanye ama-anion anamandla e-asidi). Ingasebenza kuphela ngosawoti ababuthaka be-asidi (usawoti one-alkalinity) futhi ikhiqize i-asidi ebuthaka ngemuva kokuphendula. Amanzi ane-alkalinity ephezulu angalashwa nge-resin eqinile ye-acid H-type ion resin. Ngemuva kokuthi i-anion ehambelana ne-alkalinity emanzini isusiwe, i-anion ehambelana ne-acid eqinile i-radical ingasuswa nge-asidi eqinile ye-H-type ion exchange resin.
Ngoba i-asidi cation resin ebuthakathaka inokusondelana okuphezulu kwe-H, kulula ukuyivuselela, ngakho-ke ingavuselelwa ngoketshezi lwemfucumfucu ye-resin enamandla ye-asidi yohlobo lwe-anion resin.
Umthamo wokushintshana we-asidi cation resin obuthakathaka ucishe uphindwe kabili lowo we-resin eqinile ye-acid cation. Ngoba i-crosslinking degree of weak acid cation resin iphansi, amandla ayo wokusebenza aphansi kunalawo anamandla e-acid cation resin.
Usawoti wohlobo lwe-acid cation resin unekhono le-hydrolysis.
