Ana mau ʻana o ka ʻAmonia i ka wai o ka muliwai

Ua loiloi ʻia ka maikaʻi o ka wai o ka muliwai e ka Environment Agency ma o ka papahana General Quality Assessment (GQA) a he mea nui e kāohi ʻia nā kemika ʻino i loko o ka muliwai. He meaʻai koʻikoʻi ka ʻamonia no nā mea kanu a me nā limu e noho ana i loko o ka wai o ka muliwai. Eia nō naʻe, ke loli ka mahana o ka muliwai, loli ka ʻamonia ionized i ke kinoea ʻamonia ʻaʻole i ionized. He mea make kēia i nā iʻa a me nā mea ola wai ʻē aʻe i loko o ka muliwai, no laila he mea nui e nānā mau i nā pae ʻamonia.

He mea nui nō hoʻi ka maikaʻi o ka wai no nā hale hana hoʻomaʻemaʻe wai e hoʻohana ana i ka wai muliwai ma ke ʻano he kumu. Hiki i nā pae kiʻekiʻe o ka ammonia i loko o ka wai ke hana i nā pilikia nui no ke kaʻina hana disinfection. Ma ka ana pono ʻana i nā pae ammonia i loko o ka wai muliwai ma ke komo ʻana o kahi hale hana hoʻomaʻemaʻe wai, hiki i ka hui ke pale i ka lako komo. I kekahi mau noi, hiki ke pani ʻia ke komo ʻana ke hiki i nā pae ammonia i nā pae kiʻekiʻe loa.

He pipiʻi a paʻakikī hoʻi nā ʻano hana nānā ʻana i ka ammonia o kēia manawa, hoʻohana i nā electrodes ion-selective a me nā reagents pipiʻi, he ʻawahia a paʻakikī hoʻi e lawelawe. ʻAʻole kikoʻī kēia mau monitor a koi ʻia ka hoʻoponopono mau ʻana e hoʻololi i nā pono like ʻole, e like me ka mālama ʻana i ka wai hoʻoneoneo, ka mālama ʻana i ka wai inu a me ke ana ʻana i nā pae ammonia i loko o ka wai muliwai. ʻO ka maʻamau, pono nā electrodes ion-selective i ka zeroing i kēlā me kēia lā a me ka calibration me nā reagents.

Pale aku ka mea nānā ammonia HONDE i nā pilikia o nā mea nānā ammonia kuʻuna ma ka hoʻohana ʻana i kahi ala kū hoʻokahi loa. Hoʻololi ʻia ka ammonia i kahi hui monochloramine paʻa ma kahi kūlike e like me ka pae ammonia mua. A laila ua ana ʻia ka nui o ka chloramine me ka hoʻohana ʻana i kahi sensor membrane polarographic me kahi pane linear koho i ka chloramine. Hāʻawi ka kemika hopena i ka mea nānā i ka ʻike maikaʻi loa ʻoiai ma nā pae ammonia haʻahaʻa loa (ppb).

He maʻalahi ka reagent, haʻahaʻa ke kumukūʻai a haʻahaʻa ka hoʻohana ʻana. No laila, haʻahaʻa loa ke kumukūʻai o ka loaʻa ʻana.

Ke hoʻohana nei nā ʻoihana wai nui o UK a me kekahi mau keʻena hoʻokolohua i ʻae ʻia e ka Environment Agence i nā monitor HONDE e nānā pono i nā pae ammonia i loko o ka wai o ka muliwai. Hāʻawi kēia ʻōnaehana ammonia hou mai Analytica Technologies i nā mea hoʻohana i kahi monitor i maʻalahi ke hoʻohana, hoʻokele waiwai ke kūʻai, haʻahaʻa ke holo a ʻaʻohe pilikia o ke ana ʻana.
