Mvura ndiyo tsime rehupenyu.Tinofanira kuita kuti vanhu vose vagutsikane (yakakwana, yakachengeteka uye iri nyore kuwana) mvura.Kunatsiridza kuwaniswa kwemvura yekunwa yakachena kunogona kuunza pundutso dzinobatika kuutano hweveruzhinji, uye nhamburiko dzose dzinofanira kuitwa kuti pave nechokwadi chokuti mvura yokunwa yashandiswa zvisina ngozi.Sangano reWorld Health Organisation (WHO) rakagadzirawo "Drinking Water Quality Guidelines" pamusoro pekuchengetedzwa kwemvura yekunwa, umo zvinhu zvinokanganisa hutano hwevanhu mumvura yekunwa zvinotsanangurwa nekutsanangurwa, zvinova zvakare chiratidzo chedu chekuona kuchengetedzwa kwemvura yekunwa. .Maererano neongororo yakaitwa, mazana emakemikari akawanikwa mumvura yekunwa, mamwe acho ari ekuuraya utachiona ne-products, senge bromate, chlorite, chlorate, uye mamwe anion inorganic, senge fluoride, chloride, nitrite, nitrate zvichingodaro. on.
Ion chromatography ndiyo nzira inosarudzika yekuongororwa kweiyo ionic makomisheni.Mushure memakore anopfuura makumi matatu ebudiriro, ion chromatography yave chinhu chakakosha chekuona michina yekuona mhando yemvura.Ion chromatography inoshandiswawo senzira yakakosha yekuona fluoride, nitrite, bromate uye zvimwe zvinhu muDrinking Water Quality Guidelines.
Kuonekwa kweanions mumvura yekunwa
Iwo masampula anosefa ne 0.45μm microporous filter membrane kana centrifuged.Uchishandisa CIC-D120 ion chromatograph, SH-AC-3 anion column, 2.0 mM Na2CO3/8.0 mM NaHCO3 eluent uye bipolar pulse conductance method, pasi pezvinokurudzirwa chromatographic mamiriro, chromatogram ndeyotevera.
