Amanzi ngumthombo wobomi.Kufuneka senze bonke abantu baneliseke (abanele, akhuselekile kwaye kulula ukuwafumana) ubonelelo lwamanzi.Ukuphucula ukufikelela kumanzi okusela akhuselekileyo kunokuzisa iingenelo ezibonakalayo kwimpilo yoluntu, kwaye kufuneka kwenziwe zonke iinzame zokuqinisekisa ukusetyenziswa okukhuselekileyo kwamanzi okusela.I-World Health Organization (WHO) iye yaqulunqa "Izikhokelo zoMgangatho waManzi okusela" malunga nokhuseleko lwamanzi okusela, apho izinto ezichaphazela impilo yabantu kumanzi okusela zichazwe kwaye zichazwe, nto leyo ikwayi-benchmark yethu yokuqinisekisa ukhuseleko lwamanzi okusela. .Ngokophando, amakhulu ezinto zekhemikhali ziye zachongwa kumanzi okusela, ezinye zazo ziyi-disinfection by-products, ezifana ne-bromate, i-chlorite, i-chlorate, kunye nezinye i-anion ezingaphili, ezifana ne-fluoride, i-chloride, i-nitrite, i-nitrate kunye nokunye. kwi.
Ion chromatography yindlela ekhethiweyo yohlalutyo lwee-ionic compounds.Emva kweminyaka engaphezulu kwe-30 yophuhliso, i-ion chromatography iye yaba sisixhobo esiyimfuneko sokubona umgangatho wamanzi.I-Ion chromatography ikwasetyenziswa njengendlela ebalulekileyo yokufumanisa i-fluoride, i-nitrite, i-bromate kunye nezinye izinto kwiZikhokelo zoMgangatho waManzi okuSela.
Ukufunyanwa kwee-anion emanzini okusela
Iisampuli zihluzwa nge-0.45μm ye-microporous filter membrane okanye i-centrifuged.Ukusebenzisa iCIC-D120 ion chromatograph, SH-AC-3 anion column, 2.0 mM Na2CO3/8.0 mM NaHCO3 eluent kunye nebipolar pulse conductance method, phantsi kweemeko ezicetyiswayo zechromatographic, ichromatogram imi ngolu hlobo lulandelayo.
