Mea loiloi COD pūnaewele
Kumumanaʻo ʻIke
E hoʻohui i kahi nui i ʻike ʻia o ka hopena potassium dichromate i ka hāpana wai, a hoʻohana i ka paʻakai kālā ma ke ʻano he mea hoʻoulu a me ka mercury sulfate ma ke ʻano he mea uhi i loko o kahi ʻawaʻawa ikaika. Ma hope o ka hopena digestion wela kiʻekiʻe a me ke kaomi kiʻekiʻe, e ʻike i ka absorbance o ka huahana ma kahi nalu kikoʻī. Wahi a ke kānāwai o Lambert Beer, aia kahi pilina linear ma waena o ka nui o ke koi oxygen kemika i loko o ka wai a me ka absorbance, a laila e hoʻoholo i ka nui o ke koi oxygen kemika i loko o ka wai. Nānā: He paʻakikī ke oxidize i nā mea e like me nā hydrocarbons aromatic a me pyridine i loko o ka hāpana wai, a hiki ke hoʻolōʻihi ʻia ka manawa digestion.

1. Hoʻemi iki ʻia ka nui o ka mea kālailai, kahi kūpono no ka mālama ʻana i kēlā me kēia lā;
2. Hoʻohana ʻia ka ʻenehana ana ʻana a me ka ʻike ʻana o ke kiʻekiʻe kiʻekiʻe e hoʻololi i nā kino wai paʻakikī like ʻole;
3. ʻEkolu mau pae (0-100mg/L), (0-200mg/L) a me (0-1000mg/L) e hoʻokō i ka hapa nui o nā koi nānā ʻana i ka maikaʻi o ka wai. Hiki ke hoʻonui ʻia ka pae e like me ke kūlana maoli;
4. ʻO nā ʻano ana paʻa, ka manawa, ka mālama ʻana a me nā ʻano ana ʻē aʻe e hoʻokō i nā koi o ke alapine ana;
