Mukati mekushandisa resin, kusvibiswa kwechinhu chakamiswa, zvinhu zvakasikwa nemafuta zvinofanirwa kudzivirirwa, uye kusanganiswa kwakanyanya kweimwe mvura yemarara pane resini kunofanira kudzivirirwa. Naizvozvo, ioni yesimbi inorema inofanirwa kubviswa mvura yeasidhi yakasviba isati yapinda anion resin kudzivirira catalysis yesimbi inorema pane resin. Mushure mekushandisa kwega kwega, mvura yakasviba iri mukoramu yeAAC inozodzoserwa mutangi remvura yakasviba, uye ndokunyudzwa mumvura yemupombi kana kunatswa mvura pachinzvimbo. Mushure mekuzara kwedhinari, haina kukodzera kunyudza nekupaka musarudzo yekutanga kwenguva yakareba mushure mekunge yazara, uye inofanira kusukwa munguva.
Kunyangwe iri cation resin kana anion resin, kana ichishandiswa pamatanho akati wandei, iyo AC kugona kuchaderera. Kune rimwe divi, chikonzero chekuderera kwesimba ndechekuti kusarudzwa hakuna kukwana, uye huwandu hweiyoni pane resini isiri pasi inounganidzwa zvishoma nezvishoma, izvo zvinokanganisa kuchinjika kwakajairika; Kune rimwe divi, H2CrO4 uye H2Cr2O7 mune chromium ine yakasviba mvura ine oxidation mhedzisiro, izvo zvinoita kuti cr3 + iwedzere uye yakawanda muiri, izvo zvinokanganisa mashandiro anoita resini. Naizvozvo, kana iro resin chinzvimbo chadzikira zvakanyanya, iro resin activation rinofanira kuitwa.
Iyo yekumisikidza nzira yeionion resin inofanirwa kuve yakasiyana zvinoenderana nemvura yakasviba. Chiitiko chemumba pakurapwa kwechromium ine yakasviba mvura neayion resin activation iri kubudirira. Iyo yekushanda mashandiro iri seinotevera: soak the anion resin in 2-2.5mol / 1h2so4 solution after normal, wozotora chikamu muNaHSO3 pasi pekusanganiswa zvishoma, uye kudzikisa cr6 + pane resin kusvika cr3 +. Iyo resin yakanyoroveswa mune iri pamusoro mhinduro kune rimwe zuva neusiku, ndokuzogezwa nemvura yakajeka. Dzokorora maitiro ari pamusoro aya 1-2 mazwi, wobva wabvisa cr6 + uye cr3 + muiri, wobva washandisa NaOH kushandura kuti ushandise.
Chinangwa chikuru checation activation ndechekubvisa simbi inorema ions yakaunganidzwa pane resini, kunyanya iwo akakwira mitengo ine masitepisi akasimba ane resini, senge fe3 +, cr3 +. Inogona kuitiswa mu vivo. Huwandu hwemvura yakamisikidzwa yakapetwa kaviri vhoriyamu resini. Hydrochloric acid midziyo ine huwandu hwe3.0mol / 1 inoshandiswa. Iyo dura dhata yakanyoroveswa neiyo kuyerera rate ye1-2 nguva iyo vhoriyamu resini, uye iko kusungwa kuri 2.0-2.5mol / 1 sulfuric acid solution. Zvinotora zuva rimwe chete uye zuva (kanokwana maawa masere). Iyo fe3 +, cr3 + uye mamwe esimbi inorema ioni muresini inonyatso kubviswa. Mushure mekuchenesa, iyo resin inogona kushandiswa.
