T9000 CODcr Nyochaa Akpaaka n'ịntanetị nke Ogo Mmiri
Nkọwa Dị Mkpirikpi:
Onye nyocha ahụ na-emepụta usoro oxidation dichromate ọkọlọtọ. Ọ na-ese ihe nlele mmiri mgbe ụfọdụ, na-agbakwụnye oke ziri ezi nke potassium dichromate (K₂Cr₂O₇) oxidant na concentrated sulfuric acid (H₂SO₄) na silver sulfate (Ag₂SO₄) dị ka ihe na-akpali akpali, ma na-ekpo ọkụ ngwakọta ahụ iji mee ka oxidation dịkwuo ngwa ngwa. Mgbe mgbaze gasịrị, a na-atụ dichromate fọdụrụ site na iji colorimetry ma ọ bụ potentiometric titration. Ngwaọrụ ahụ na-agbakọ mkpokọta COD dabere na oriri oxidant.
