I-T9000 CODcr Umgangatho Wamanzi Okwi-Intanethi Ozenzekelayo

Inkcazo emfutshane:

Imfuno ye-oksijini yekhemikhali (i-COD) ibhekisa kuxinzelelo olukhulu lwe-oksijini esetyenziswa zii-oxidants xa kufakwa izinto ezincitshisayo ze-organic kunye ne-inorganic kwiisampuli zamanzi ezine-oxidants ezinamandla phantsi kweemeko ezithile. I-COD ikwaluphawu olubalulekileyo olubonisa inqanaba longcoliseko lwamanzi yizinto ezincitshisayo ze-organic kunye ne-inorganic. I-analyzer yenza ngokuzenzekelayo indlela eqhelekileyo ye-dichromate oxidation. Itsala rhoqo isampuli yamanzi, yongeza iivolumu ezichanekileyo ze-potassium dichromate (K₂Cr₂O₇) oxidant kunye ne-concentrated sulfuric acid (H₂SO₄) nge-silver sulfate (Ag₂SO₄) njenge-catalyst, kwaye ifudumeza umxube ukukhawulezisa i-oxidation. Emva kokugaya, i-dichromate eseleyo ilinganiswa nge-colorimetry okanye i-potentiometric titration. Isixhobo sibala uxinzelelo lwe-COD ngokusekelwe ekusetyenzisweni kwe-oxidant. Iimodeli eziphambili zidibanisa ii-reactors zokugaya, iinkqubo zokupholisa, kunye neemodyuli zokuphatha inkunkuma ukuze kukhuseleke kwaye kuchaneke.

1.Isishwankathelo seMveliso:

Imfuno ye-oksijini yekhemikhali (i-COD) ibhekisa kuxinzelelo olukhulu lwe-oksijini esetyenziswa zi-oxidants xa kufakwa i-oxidizethi yezinto ezinciphisayo ze-organic kunye ne-inorganic kwiisampuli zamanzi ezine-oxidants ezinamandla phantsi kweemeko ezithile. I-COD ikwaluphawu olubalulekileyo olubonisa inqanaba longcoliseko lwamanzi zizinto ezinciphisayo ze-organic kunye ne-inorganic.

I-analyzer ingasebenza ngokuzenzekelayo nangokuqhubekayo ixesha elide ngaphandle kokujonga ngokwezicwangciso zendawo. Isetyenziswa kakhulu kumanzi amdaka akhutshwayo avela kumthombo wongcoliseko lwemizi-mveliso, amanzi amdaka enkqubo yemizi-mveliso, amanzi amdaka esityalo sokucocwa kwamanzi amdaka emizi-mveliso, amanzi amdaka esityalo sokucocwa kwamanzi amdaka kamasipala kunye neminye imicimbi. Ngokweemeko zovavanyo lwendawo, inkqubo yonyango lwangaphambi konyango efanelekileyo inokukhethwa ukuqinisekisa ukuba inkqubo yovavanyo ithembekile, iziphumo zovavanyo zichanekile, kwaye ziyahlangabezana ngokupheleleyo neemfuno zeziganeko ezahlukeneyo.

2.Umgaqo weMveliso:

Iisampulu zamanzi, isisombululo sokugaya i-potassium dichromate, isisombululo se-silver sulfate (i-silver sulfate njenge-catalyst ingongezwa kwi-oxidize linear aliphatic compounds ngempumelelo ngakumbi) kunye nomxube we-sulfuric acid oxineneyo oshushu ukuya kwi-175℃. Umbala wee-organic compounds kwisisombululo se-dichromate ion oxidation uya kutshintsha. I-analyzer ibona utshintsho lombala kwaye iguqula utshintsho lube yi-COD value ize ikhuphe ixabiso. Ubungakanani be-dichromate ion esetyenzisiweyo bulingana nobungakanani be-oxidizable organic matter, oko kukuthi i-COD.
