The chemical oxygen demand test is
The chemical oxygen demand test is used widely to estimate the amount of organic matter in waste water. It is a measurement of the oxygen equivalent of the materials present in tehe waste water that are subject to oxidation by a stong chemical oxydant, in this case dichromate. The ultra low range COD reagent is designed for use with water and waste water effluent samples. In the reactor digestion method test, the COD procedure is greatly simplified. 2 ml water samples are pipetted ito vials are digest at 150⁰C for two hour and cooled.then the COD determination is made with a
Because of the low measurement and sensitivity of this method t is important the container does not contribute to final COD measurement. Collect sample in gass bottles if possible. Plastics bottle can be used only o if they are known to be free of organic contamination. Biologically active sample should be tested as son as possible. Sample containing solids should to well-mixed or homoginezed to permit the removalof a representative aliquot. Note : the following storage instruction are necessary only when prompt analysis is impossible. Add two ml sulfuric acid, ACS, for each liter or quart of sample using a glass serological pipet and pipet filler. Mix. Check the sample to be sure the pH is 2 or less. Add more acid if necessary. Sample preserved in ths manner can be stored for 7 days. Where significant amounts of preservatives are used, a volume correction should be made for the extra acid by dividing the total volume (sample + acod) by the sample volume and multiplying the test result by this factor.

Tes kimia oksigen demand digunakan secara luas untuk memperkirakan jumlah bahan organik dalam air limbah. Itu adalah pengukuran oksigen setara dengan bahan-bahan yang hadir dalam tehe air limbah yang dapat oksidasi oleh stong oxydant kimia, dalam dichromate kasus ini. Kisaran rendah ultra COD reagen dirancang untuk digunakan dengan air dan air limbah limbah sampel. Dalam reaktor pencernaan tes metode, prosedur COD sangat disederhanakan. 2 ml air sampel pipetted ito cawan mencerna di 150⁰C untuk dua jam dan penentuan cooled.then COD dibuat dengan Karena rendah pengukuran dan kepekaan dari metode ini t penting wadah tidak berkontribusi pada akhir pengukuran COD. Mengumpulkan sampel dalam botol gass jika mungkin. Botol plastik dapat digunakan hanya o Jika mereka dikenal harus bebas dari kontaminasi organik. Sampel biologis aktif harus diuji sebagai anak mungkin. Sampel yang mengandung padatan harus baik campuran atau homoginezed untuk mengizinkan removalof wakil aliquot. Catatan: instruksi penyimpanan berikut diperlukan hanya bila prompt analisis mustahil. Menambahkan dua ml asam sulfat, ACS, untuk setiap liter atau liter contoh menggunakan pipet serological kaca dan pipet pengisi. Campuran. memeriksa sampel untuk memastikan pH 2 atau kurang. Tambahkan lebih banyak asam jika diperlukan. Sampel yang diawetkan dengan cara ths dapat disimpan selama 7 hari. Mana sejumlah besar bahan pengawet yang digunakan, koreksi volume harus dibuat untuk asam tambahan dengan membagi total volume (sampel + acod) dengan volume sampel dan mengalikan hasil tes dengan faktor ini.
