Iṣiro ti iwọn lilo aṣoju decolorizing (mu idanwo kan pato bi apẹẹrẹ)

1.Dosage ti reagent (PPM) = [(nọmba silẹ / 20) × ifọkansi dilution / iwọn didun omi idọti idanwo] ×106

★ PPM jẹ apakan kan fun miliọnu kan, ati iwọn lilo jẹ 1PPM, eyiti o jẹ deede ton ti omi idọti, iwọn lilo aṣoju jẹ gram 1.

★ 1ML ti fomi ojutu jẹ deede si 20 silė

2.Lo beaker lati mu 200ML ti omi idọti idanwo (chroma 200, COD 110), ṣatunṣe iye PH si 8, ṣafikun 10 silė tiaṣoju decolorizingojutu pẹlu eyedropper (1ML jẹ deede si 20 silė), aruwo, lẹhinna fi 12 silė PAC, ru, ati nikẹhin fi 2 silė ti PAM, ru, ki o si duro fun iṣẹju kan. chroma wiwa jẹ 4 (ọna dilution ọpọ) ati COD jẹ 85, eyiti o ni ibamu pẹlu boṣewa itujade orilẹ-ede.

3. Iwọn lilo ti igbaradi reagent:aṣoju decolorizing(ojutu 2%, iyẹn ni, fomipo awọn akoko 50), PAC (ojutu 2%), PAM (ojutu olomi 1‰)

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

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

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

Awọn iye tiaṣoju decolorizingni 50PPM, eyi ti o jẹ deede si 50 giramu ti awọnaṣoju decolorizingojutu ọja ni toonu kan ti omi idọti, ati bẹbẹ lọ, PAC jẹ giramu 60, ati PAM jẹ giramu 0.5.
