Ukubalwa kwedosi ye-arhente ye-decolorizing (ukuthatha uvavanyo oluthile njengomzekelo)

1.Umthamo we-reagent (PPM) = [(inombolo yokulahla / 20) × i-dilution concentration / umthamo wamanzi amdaka ovavanyo] × 106

★ I-PPM yinxalenye yesigidi ngasinye, kwaye i-dosage yi-1PPM, elingana ne-1 ton yamanzi amdaka, i-dosage ye-arhente yi-1 gram.

★ 1ML isisombululo esihlanjululweyo silingana namathontsi angama-20

2.Sebenzisa ibhekile ukuthatha i-200ML yamanzi amdaka ovavanyo (chroma 200, COD 110), lungisa ixabiso le-PH kwi-8, yongeza i-10 yehlaiarhente yokususa umbalaisisombululo nge-eyedropper (i-1ML ilingana namaconsi angama-20), ugxobhoze, uze udibanise i-12 ye-PAC, ugxobhoze, kwaye ekugqibeleni udibanise ama-2 amaconsi e-PAM, ugxobhoze, kwaye ume ngomzuzu omnye. I-chroma yokubona yi-4 (i-dilution multiple method) kunye ne-COD yi-85, ehlangabezana nomgangatho wokukhutshwa kwelizwe.

3. Umthamo wokulungiswa kwe-reagent:iarhente yokususa umbala(2% isisombululo, oko kukuthi, i-dilution amaxesha angama-50), i-PAC (isisombululo se-2%), i-PAM (1 ‰ isisombululo samanzi)

Isixa seiarhente yokususa umbala= [(10/20) ×2%/200] ×106 = 50PPM

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

Isixa sePAM = [(2/20) × 1‰/200] × 106 = 0.5PPM

Isixa seiarhente yokususa umbalayi 50PPM, nto leyo ilingana 50 grams yeiarhente yokususa umbalaisisombululo sesitokhwe kwitoni enye yamanzi amdaka, njalo njalo, iPAC yi-60 grams, kunye ne-PAM yi-0.5 grams.
