1.Umthamo we-reagent (PPM) = [(inombolo yokulahla /20) × ukugxiliswa kwe-dilution/umthamo wamanzi angcolile okuhlola] ×106
★ I-PPM ingxenye eyodwa kwesigidi, futhi umthamo yi-1PPM, okulingana nethani elingu-1 lamanzi angcolile, umthamo we-ejenti yi-1 gram.
★ Isixazululo esihlanjululwe esingu-1ML silingana namathonsi angama-20
2.Sebenzisa ibhika ukuthatha u-200ML wamanzi angcolile okuhlola (chroma 200, COD 110), lungisa inani le-PH libe ngu-8, engeza amaconsi angu-10i-ejenti ye-decolorizingisixazululo nge-eyedropper (i-1ML ilingana namaconsi angu-20), gubungula, bese wengeza amaconsi angu-12 e-PAC, ugovuze, futhi ekugcineni wengeze amaconsi angu-2 we-PAM, ugovuze, futhi ume umzuzu owodwa. I-chroma yokuthola ithi 4(indlela yokuhlanjululwa okuningi) futhi i-COD ingu-85, ehlangabezana nezinga likazwelonke lokukhipha umoya.
3. Umthamo wokulungiswa kwe-reagent:i-ejenti ye-decolorizing(2% isixazululo, okungukuthi, dilution izikhathi 50), PAC (2% isixazululo), PAM (1‰ isixazululo aqueous)
Inani lei-ejenti ye-decolorizing= [(10/20) ×2%/200] ×106 = 50PPM
PAC umthamo = [(12/20) ×2%/200] ×106 = 60PPM
Inani le-PAM = [(2/20) ×1‰/200] ×106 = 0.5PPM
Inani lei-ejenti ye-decolorizingingu-50PPM, okulingana namagremu angu-50 we-i-ejenti ye-decolorizingisixazululo sesitoko ethoni elilodwa lamanzi angcolile, nokunye, i-PAC ingamagremu angu-60, kanti i-PAM ingu-0.5 amagremu.
