Madzi ndiye gwero la moyo.Tiyenera kupangitsa anthu onse kukhala okhutira (okwanira, otetezeka komanso osavuta kupeza) madzi.Kupititsa patsogolo mwayi wopeza madzi abwino akumwa kungabweretse phindu lowoneka paumoyo wa anthu, ndipo kuyesetsa kulikonse kuyenera kuchitidwa kuti madzi akumwa agwiritsidwe ntchito moyenera.Bungwe la World Health Organization (WHO) lapanganso "Drinking Water Quality Guidelines" pa chitetezo cha madzi akumwa, momwe zinthu zomwe zimakhudza thanzi la munthu m'madzi akumwa zimafotokozedwa ndi kufotokozedwa, zomwenso ndi chizindikiro chathu chowonetsetsa chitetezo cha madzi akumwa. .Malinga ndi kafukufukuyu, mazana azinthu zamadzimadzi zapezeka m'madzi akumwa, zina zomwe zimapha tizilombo toyambitsa matenda, monga bromate, chlorite, chlorate, ndi ma anion ena osakhazikika, monga fluoride, chloride, nitrite, nitrate ndi zina zotero. pa.
Ion chromatography ndiyo njira yabwino kwambiri yowunikira ma ionic mankhwala.Pambuyo pazaka zopitilira 30 zachitukuko, chromatography ya ion yakhala chida chofunikira kwambiri chodziwira madzi.Ion chromatography imagwiritsidwanso ntchito ngati njira yofunikira yodziwira fluoride, nitrite, bromate ndi zinthu zina mu Upangiri wa Madzi Akumwa.
Kuzindikira kwa anions m'madzi akumwa
Zitsanzozo zimasefedwa ndi 0.45μm microporous filter membrane kapena centrifuged.Pogwiritsa ntchito CIC-D120 ion chromatograph, SH-AC-3 anion column, 2.0 mM Na2CO3/8.0 mM NaHCO3 eluent ndi bipolar pulse conductance njira, pansi pa chromatographic yovomerezeka, chromatogram ili motere.
