Amanzi awumthombo wokuphila.Kufanele senze bonke abantu baneliseke (anele, aphephile futhi kulula ukuwathola) amanzi.Ukwenza ngcono ukutholakala kwamanzi okuphuza aphephile kungaletha izinzuzo ezibonakalayo empilweni yomphakathi, futhi kufanele kwenziwe yonke imizamo yokuqinisekisa ukusetshenziswa okuphephile kwamanzi okuphuza.I-World Health Organization (WHO) iphinde yenza "Iziqondiso Zekhwalithi Yamanzi Okuphuza" mayelana nokuphepha kwamanzi okuphuza, lapho kuchazwa futhi kuchazwa izinto ezithinta impilo yomuntu emanzini okuphuza, okubuye kube uphawu lwethu lokuqinisekisa ukuphepha kwamanzi okuphuza. .Ngokophenyo, kuye kwatholakala amakhulukhulu ezinto zamakhemikhali emanzini okuphuza, ezinye zazo okuyimikhiqizo ebulala amagciwane, njenge-bromate, i-chlorite, i-chlorate, namanye ama-anion angaphili, njenge-fluoride, i-chloride, i-nitrite, i-nitrate nokunye. ku.
I-Ion chromatography iyindlela ekhethwayo yokuhlaziywa kwezinhlanganisela ze-ionic.Ngemva kweminyaka engaphezu kwengu-30 yokuthuthuka, i-ion chromatography isiphenduke isisetshenziswa esibalulekile sokuthola ikhwalithi yamanzi.I-Ion chromatography iphinde isetshenziswe njengendlela ebalulekile yokuthola i-fluoride, i-nitrite, i-bromate nezinye izinto Eziqondisweni Zekhwalithi Yamanzi Okuphuza.
Ukutholwa kwama-anion emanzini okuphuza
Amasampuli ahlungwa ngolwelwesi lwesihlungi se-microporous esingu-0.45μm noma i-centrifuged .Kusetshenziswa i-CIC-D120 ion chromatograph, ikholomu ye-anion ye-SH-AC-3, 2.0 mM Na2CO3/8.0 mM NaHCO3 eluent kanye nendlela ye-bipolar pulse conductance, ngaphansi kwezimo ze-chromatographic ezinconyiwe, i-chromatogram imi kanje.
