Te tātaitanga o te inenga o te kaihoko whakaheke tae (whakamatautau motuhake hei tauira)

1.Te inenga o te reagent (PPM) = [(te nama maturuturu /20) × te kukū waimeha/te rahi o te wai para whakamatautau] ×106

★ Ko te PPM tetahi wahanga mo te miriona, a ko te inenga he 1PPM, he rite ki te 1 tana o te wai para, ko te inenga o te kaihoko he 1 karamu.

★ 1ML otinga diluted he rite ki te 20 pata

2.Whakamahia he ipurau hei tango i te 200ML o te wai para whakamatautau (chroma 200, COD 110), whakatikahia te uara PH ki te 8, taapirihia kia 10 nga pata ote kai whakakore taete otinga me te karu (1ML he rite ki te 20 pata), whakaohokia, katahi ka tapirihia kia 12 nga pata o te PAC, whakaohokia, ka mutu ka tapirihia kia 2 nga pata PAM, whakaohokia, ka tu mo te meneti kotahi. Ko te chroma rapunga he 4(nga tikanga maha te dilution) me te COD he 85, e tutuki ana ki te paerewa tukunga a-motu.

3. Ko te inenga o te whakarite reagent:te kai whakakore tae(2% wairewa, ara, waimeha 50 wa), PAC (2% otinga), PAM(1‰ wairewa wai)

Te nui ote kai whakakore tae= [(10/20) ×2%/200] ×106 = 50PPM

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

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

Te nui ote kai whakakore taehe 50PPM, he rite ki te 50 karamu o tete kai whakakore taehe otinga kararehe i roto i te kotahi tana o te wai para, me era atu, ko te PAC he 60 karamu, ko te PAM he 0.5 karamu.
