Ngenqubo yokusebenzisa i-resin, ukungcoliswa kwento emisiwe, okokusebenza okuphilayo kanye no-oyili kufanele kugwenywe, futhi kufanele kugwenywe uketshezi olunzima lwamanzi angcolile athile ku-resin. Ngakho-ke, ion esindayo kufanele isuswe ngaphambi kokuba amanzi angcolile e-acid oxidation angene ku-resin ye-anion ukugwema uketshezi lwezinsimbi ezisindayo ku-resin. Ngemuva kokuthi imishini ngayinye isebenze, amanzi angcolile kukholamu ye-AC azobuyiselwa ethangini lamanzi angcolile, bese efakwa emanzini ompompi noma ngamanzi ahlanziwe esikhundleni salokho. Ngemuva kokuthi i-resin igcwele, akulungile ukucwilisa nokupaka isixazululo sokuqala isikhathi eside ngemuva kokuthi igcwele, futhi kufanele igezwe ngesikhathi.
Noma ngabe i-cation resin noma i-anion resin, uma isetshenziselwa imijikelezo eminingana, umthamo we-AC uzokwehla. Ngakolunye uhlangothi, isizathu sokwehla kwamandla ukuthi ukukhethwa akuphelele, futhi inani le-ions ku-resin engekho phansi liqoqwa kancane kancane, okuthinta ukushintshaniswa okuvamile; Ngakolunye uhlangothi, i-H2CrO4 ne-H2Cr2O7 ku-chromium equkethe amanzi angcolile inomthelela we-oxidation ku-resin, okwenza i-cr3 + iqhubeke ngokwengeziwe ku-resin, ethinta ukusebenza okuvamile kwe-resin. Ngakho-ke, lapho amandla we-resin enokuncipha okukhulu, ukwenziwa kwe-resin kufanele kwenziwe.
Indlela yokwenza kusebenze i-anion resin kufanele yehluke ngokwamanzi angcolile. Okuhlangenwe nakho kwasendlini ekwelapheni i-chromium equkethe amanzi angcolile nge-anion resin activation kuphumelela kakhulu. Ukusebenza kwesimiso kungokulandelayo: cwilisa i-anion resin ku-2-2.5mol / 1h2so4 solution ngemuva kokujwayelekile, bese ubamba iqhaza ku-NaHSO3 ngaphansi kokuxubana okuhamba kancane, bese unciphisa i-cr6 + ku-resin iye ku-cr3 +. I-resin icwiliswe kusixazululo esingenhla usuku olulodwa nobusuku, bese igezwa ngamanzi acacile. Phinda inqubo engenhla yamagama ayi-1-2, bese ususa u-cr6 + no-cr3 + ku-resin, bese usebenzisa i-NaOH ukuguqula ukuze isetshenziswe.
Inhloso enkulu yokwenza kusebenze i-cation ukususa ama-ayoni esimbi anqwabelene ku-resin, ikakhulukazi lawo mazwe anentengo ephezulu ngamandla aqinile okubopha ane-resin, njenge-fe3 +, cr3 +. Ingasebenza ku-vivo. Inani loketshezi olucushiwe liphindwe kabili umthamo we-resin. Kusetshenziswa imishini ye-Hydrochloric acid ene-3.0mol / 1. Isendlalelo se-resin sifakwe ngesilinganiso sokugeleza kwezikhathi ezingu-1-2 ivolumu ye-resin, futhi ukuhlushwa kuyisixazululo se-2.0-2.5mol / 1 sulfuric acid solution. Kuthatha usuku olulodwa nosuku (okungenani amahora ayi-8). I-fe3 +, i-cr3 + namanye ama-ayoni esimbi asindayo asenqolobaneni asuswa ngokuyisisekelo. Ngemuva kokuhlanza, i-resin ingasetshenziswa.
