I-T9000 CODcr Ikhwalithi Yamanzi Ezenzakalelayo Ekwi-inthanethi Isithombe Esifakiwe

I-T9000 CODcr Ikhwalithi Yamanzi Ezenzakalelayo Eku-inthanethi

Incazelo emfushane:

Isidingo se-oxygen yamakhemikhali (i-COD) sibhekisela ekugxilweni okukhulu kwe-oxygen edliwa ama-oxidant lapho kufakwa i-oxidizing izinto ezincishisa izinto eziphilayo nezingaphili kumasampula amanzi anama-oxidant aqinile ngaphansi kwezimo ezithile. I-COD futhi iyinkomba ebalulekile ekhombisa izinga lokungcoliswa kwamanzi yizinto ezincishisa izinto eziphilayo nezingaphili. I-analyzer yenza ngokuzenzakalelayo indlela ejwayelekile ye-dichromate oxidation. Idonsa njalo isampula yamanzi, yengeze amavolumu aqondile e-potassium dichromate (K₂Cr₂O₇) oxidant kanye ne-concentrated sulfuric acid (H₂SO₄) nge-silver sulfate (Ag₂SO₄) njenge-catalyst, futhi ifudumale ingxube ukuze isheshise i-oxidation. Ngemuva kokugaya, i-dichromate esele ilinganiswa nge-colorimetry noma i-potentiometric titration. Ithuluzi libala ukugxilwa kwe-COD ngokusekelwe ekusetshenzisweni kwe-oxidant. Amamodeli athuthukile ahlanganisa ama-reactor okugaya, izinhlelo zokupholisa, kanye namamojula okuphatha imfucuza ukuze kuphephe futhi kunembile.

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

1.Ukubuka konke komkhiqizo:

Isidingo se-chemical oxygen (COD) sibhekisela ekuqongeleleni okukhulu kwe-oxygen edliwa ama-oxidants lapho kufakwa i-oxidizing organic kanye ne-inorganic reduction stuff kumasampula amanzi anama-oxidants aqinile ngaphansi kwezimo ezithile. I-COD futhi iyinkomba ebalulekile ekhombisa izinga lokungcoliswa kwamanzi yizinto ezincishisa izinto eziphilayo kanye ne-inorganic.

I-analyzer ingasebenza ngokuzenzakalelayo nangokuqhubekayo isikhathi eside ngaphandle kokufika ngokwezilungiselelo zesayithi. Isetshenziswa kabanzi emanzini angcolile okukhishwa ngumthombo wokungcola kwezimboni, amanzi angcolile enqubo yezimboni, amanzi angcolile esitshalo sokwelapha indle sezimboni, amanzi angcolile esitshalo sokwelapha indle sikamasipala kanye nezinye izikhathi. Ngokuya ngobunzima bezimo zokuhlola indawo, uhlelo lokwelapha oluhambisanayo lungakhethwa ukuqinisekisa ukuthi inqubo yokuhlola ithembekile, imiphumela yokuhlolwa inembile, futhi ihlangabezana ngokugcwele nezidingo zezikhathi ezahlukene.

2.Isimiso Somkhiqizo:

Amasampula amanzi, isixazululo sokugaya i-potassium dichromate, isixazululo se-silver sulfate (i-silver sulfate njenge-catalyst ingangezwa ukuze i-oxidize ama-compounds e-aliphatic aqondile kahle kakhulu) kanye nengxube ye-sulfuric acid egxilile eshiswa ku-175℃. Umbala wama-compounds e-organic kusisombululo se-dichromate ion oxidation uzoshintsha. I-analyzer ithola ushintsho lombala bese iguqula ushintsho lube yinani le-COD bese ikhipha inani. Inani lama-ion e-dichromate asetshenziswayo lilingana nenani lezinto eziphilayo ezikwazi uku-oxida, okuyi-COD.

3.Amapharamitha Obuchwepheshe:
