Fuafuaga o vailaʻau faʻamaʻi (faʻaaogaina o suʻega faʻapitoa e fai ma faʻataʻitaʻiga)

1. Fuafuaga o le reagent (PPM) = [(numera pa'ū /20) × fa'asusu fa'afefeteina/volo ole su'esu'e vai otaota] ×106

★ PPM e tasi le vaega i le miliona, ma o le fua o le 1PPM, lea e tutusa ma le 1 tone o otaota otaota, o le fua o le sooupu o le 1 gram.

★ 1ML diluted fofo e tutusa ma le 20 mataua

2. Fa'aaoga se ipu inu e ave ai le 200ML ole su'esu'e vai otaota (chroma 200, COD 110), fa'afetaui le tau ole PH ile 8, fa'aopoopo 10 mataua olesui fa'a'ofuofuvaifofo ma le mata (1ML e tutusa ma le 20 mataua), faʻafefe, ona faʻaopopo lea o le 12 mataua o le PAC, faʻafefe, ma mulimuli ane faʻaopopo le 2 mataua o le PAM, faʻafefe, ma tu mo le minute e tasi. Ole su'esu'ega chroma ole 4(dilution multiple method) ma le COD o le 85, lea e fetaui ma le atunu'u emission standard.

3. Ole fua ole sauniuniga ole reagent:sui fa'a'ofuofu(2% fofo, o lona uiga, fa'afefeteina 50 taimi), PAC (2% fofo), PAM(1‰ vaifofo vai)

Ole aofaiga olesui fa'a'ofuofu= [(10/20) ×2%/200] ×106 = 50PPM

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

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

Ole aofaiga olesui fa'a'ofuofue 50PPM, lea e tutusa ma le 50 kalama o lesui fa'a'ofuofufa'asoa vaifofo i totonu o le tasi tone o vai otaota, ma isi, PAC e 60 kalama, ma PAM e 0.5 kalama.
