Kwinkqubo yokusebenzisa i-resin, ungcoliseko lwezinto ezixhonyiweyo, izinto eziphilayo kunye neoyile kufuneka zithintelwe, kwaye i-oxidation eqatha yamanzi amdaka akwintlaka kufuneka ithintelwe. Ke ngoko, ii-ion zentsimbi enzima kufuneka zisuswe ngaphambi kokuba amanzi amdaka e-acid oxidation angene kwi-resin ye-anion ukuthintela i-catalysis yesinyithi esinzima kwi-resin. Emva kokuba isixhobo ngasinye sisebenza, amanzi amdaka kwikholamu ye-AC aya kuphinda abuyiselwe kwitanki lamanzi amdaka, emva koko afakwe emanzini apompo okanye acociweyo endaweni yoko. Emva kokuba i-resin igcwele, ayifanelekanga ukucwina kunye nokupaka kwisisombululo sokuqala ixesha elide emva kokuba lizele, kwaye kufuneka lihlanjwe ngexesha.
Nokuba yicin resin okanye i-anion resin, xa isetyenziselwa imijikelezo eliqela, amandla e-AC aya kuncipha. Kwelinye icala, isizathu sokuncipha komthamo kukuba ukhetho aluphelelanga, kwaye isixa se-ion kwi-resin engekho phantsi iyaqokelelwa ngokuthe ngcembe, echaphazela ukutshintshiselana okuqhelekileyo; Kwelinye icala, i-H2CrO4 kunye ne-H2Cr2O7 kwi-chromium enamanzi amdaka inefuthe le-oxidation, eyenza i-cr3 + ngakumbi nangakumbi kwi-resin, echaphazela ukusebenza okuqhelekileyo kwentlaka. Ke ngoko, xa amandla e-resin enokuhla okubonakalayo, ukwenziwa kwentlaka kufuneka kwenziwe.
Indlela yokusebenza ye-anion resin kufuneka yahluke ngokwamanzi amdaka. Amava asekhaya kunyango lwe-chromium equkethe amanzi amdaka nge-anion resin activation iyaphumelela. Ukusebenza komgaqo kulandelayo: cwina i-anion resin kwisisombululo se-2-2.5mol / 1h2so4 emva kwesiqhelo, emva koko uthathe inxaxheba kwi-NaHSO3 phantsi kokuxubeka kancinci, kwaye unciphise i-cr6 + kwi-resin ukuya kwi-cr3 +. I-resin ifakwe kwisisombululo esingentla ngemini enye nobusuku, ize ihlanjwe ngamanzi acacileyo. Phinda le nkqubo ingentla yamagama ayi-1-2, emva koko ususe i-cr6 + kunye ne-cr3 + kwi-resin, emva koko usebenzise i-NaOH ukuguqula ukusetyenziswa.
Eyona njongo iphambili yokuvula i-cation kukususa ii-ioni zentsimbi enzima eqokelelwe kwi-resin, ngakumbi ezo ndawo zixabiso liphezulu zinamandla okubopha nge-resin, njenge-fe3 +, cr3 +. Inokwenziwa isebenze kwi vivo. Isixa solwelo olusebenzayo siphindaphindwe kabini umthamo wentlaka. Isixhobo se-Hydrochloric acid esine-3.0mol / 1 sisetyenziswa. Uluhlu lwentlaka lufakwe kwinqanaba lokuhamba kwamaxesha e-1-2 umthamo we-resin, kwaye uxinzelelo yi-2.0-2.5mol / 1 isisombululo seasidi yesalfure. Kuthatha usuku olunye kunye nemini (ubuncinci iiyure ezi-8). I-fe3 +, i-cr3 + kunye nezinye ion zentsimbi enzima kwi-resin zisuswe ngokusisiseko. Emva kokuhlanjwa, i-resin inokusetyenziswa.
