Ƙididdigar adadin adadin wakilai na lalata (ɗaukakin gwaji na musamman a matsayin misali)

1.Dosage na reagent (PPM) = [(digo lamba / 20) × dilution maida hankali / girma na gwajin sharar gida] ×106

★ PPM kashi daya ne ga miliyan daya, kuma adadin shine 1PPM, wanda yayi daidai da ton 1 na ruwan datti, ma'auni na wakili shine gram 1.

★ Maganin diluted 1ML daidai yake da saukad da 20

2.Yi amfani da beaker don ɗaukar 200ML na gwajin datti (chroma 200, COD 110), daidaita ƙimar PH zuwa 8, ƙara digo 10 nawakili decolorizingMagani tare da eyedropper (1ML daidai yake da digo 20), motsawa, sannan a ƙara digo 12 na PAC, motsawa, sannan a ƙara digo 2 na PAM, motsawa, sannan a tsaya na minti daya. Gano chroma shine 4 (hanyar dilution mahara) kuma COD shine 85, wanda ya dace da ma'aunin fitar da iska na ƙasa.

3. The sashi na reagent shiri:wakili decolorizing(2% bayani, wato, dilution sau 50), PAC (2% bayani), PAM (1 ‰ aqueous bayani)

Adadinwakili decolorizing= [(10/20) ×2%/200] ×106 = 50PPM

Matsakaicin PAC = [(12/20) ×2%/200] ×106 = 60PPM

Adadin PAM = [(2/20) ×1‰/200] ×106 = 0.5PPM

Adadinwakili decolorizingshine 50PPM, wanda yayi daidai da gram 50wakili decolorizingMaganin jari a cikin tan ɗaya na ruwan sharar gida, da sauransu, PAC shine gram 60, kuma PAM shine gram 0.5.
