ʻO ka wai ke kumu o ke ola.Pono mākou e māʻona i nā kānaka a pau (kūpono, palekana a maʻalahi hoʻi) ka lako wai.ʻO ka hoʻomaikaʻi ʻana i ka loaʻa ʻana o ka wai inu palekana hiki ke lawe mai i nā pōmaikaʻi maoli i ke olakino lehulehu, a pono e hana ʻia nā hana āpau e hōʻoia i ka hoʻohana palekana ʻana i ka wai inu.Ua hoʻokumu pū ka World Health Organization (WHO) i ka "Drinking Water Quality Guidelines" e pili ana i ka palekana o ka wai inu, kahi i wehewehe ʻia a wehewehe ʻia nā mea e pili ana i ke olakino o ke kanaka i ka wai inu, ʻo ia hoʻi kā mākou pae no ka hōʻoia ʻana i ka palekana o ka wai inu. .E like me ka hoʻokolokolo ʻana, ua ʻike ʻia he mau haneli o nā mea kemika i ka wai inu, ʻo kekahi o ia mau mea he disinfection by-products, e like me bromate, chlorite, chlorate, a me nā anion inorganic ʻē aʻe, e like me ka fluoride, chloride, nitrite, nitrate a pēlā aku. ma.
ʻO ka Ion chromatography ka mea i makemake ʻia no ka nānā ʻana i nā pūhui ionic.Ma hope o 30 mau makahiki o ka hoʻomohala ʻana, ua lilo ka ion chromatography i mea pono pono no ka ʻike ʻana i ka maikaʻi o ka wai.Hoʻohana ʻia ʻo Ion chromatography i mea koʻikoʻi no ka ʻike ʻana i ka fluoride, nitrite, bromate a me nā mea ʻē aʻe i loko o nā alakaʻi maikaʻi o ka wai inu.
Ka ʻike ʻana o nā anion i ka wai inu
Hoʻopili ʻia nā laʻana e 0.45μm microporous kānana membrane a i ʻole centrifuged.Ke hoʻohana nei i ka CIC-D120 ion chromatograph, SH-AC-3 anion column, 2.0 mM Na2CO3/8.0 mM NaHCO3 eluent a me ka bipolar pulse conductance method, ma lalo o nā kūlana chromatographic i ʻōlelo ʻia, penei ka chromatogram.
