T9000ʻO ka maikaʻi o ka wai ʻo CODcr ma luna o ka laina
Kumu Huahana
ʻO nā laʻana wai, potassium dichromate digestion solution, silver sulfate solution (silver sulfate as catalyst to oxidize linear aliphatic compounds ʻoi aku ka maikaʻi) a concentrated sulfuric acid mixture i hoʻomehana ʻia i 175 ℃. E hoʻololi ke kala o nā mea hoʻohui i loko o ka dichromate ion oxidation solution. ʻIke ka mea anala i ka hoʻololi kala a hoʻololi i ka hoʻololi ʻana i ka waiwai COD a laila hoʻopuka i ka waiwai. ʻO ka nui o ka dichromate ion i hoʻopau ʻia e like me ka nui o nā mea organik oxidizable, ʻo ia hoʻi COD.

10 | ʻAna pōʻaiapuni | He 20 minuke. E like me ka laʻana wai maoli, hiki ke hoʻonohonoho ʻia ka manawa digestion mai 5 a 120 mau minuke. |
11 | Ka wā laʻana | Hiki ke hoʻonohonoho ʻia ke ʻano ana o ka manawa (hoʻololi ʻia), ka hola hoʻohui a i ʻole ke ʻano hoʻokalakupua. |
12 | Hoʻolālikelike pōʻaiapuni | ʻO ka calibration aunoa (1-99 mau lā hiki ke hoʻololi ʻia), e like me nā ʻano wai maoli, hiki ke hoʻonohonoho ʻia ka calibration manual. |
13 | pōʻai mālama | ʻOi aku ka manawa o ka mālama ʻana ma mua o hoʻokahi mahina, ma kahi o 30 mau minuke i kēlā me kēia manawa. |
