Iityhubhu zoVavanyo lwe-COD eziveliswe yi-Aijiren zihlala zisetyenziselwa ukubona imfuno ye-oksijini yemichiza. Iglasi esetyenziswa kwi-COD Test Tubes eveliswe ngu-Aijiren inokumelana nobushushu obuphezulu, ukumelana nokugqwala, kwaye inokukhusela iisampulu ngaphandle kokuchaphazela iziphumo zovavanyo. Iimathiriyeli ekrwada zika-Aijiren zikumgangatho ophezulu kunye namava emveliso Ubuninzi, ngamaxabiso alungileyo emveliso, ngumboneleli okumgangatho ophezulu wezinto ezityiwayo zechromatographic./p>

Uvavanyo lwe-Chemical Oxygen Demand (COD) lusetyenziswa ngokubanzi njengomlinganiselo wokungcola kwezinto eziphilayo ngokumisela ubuninzi be-oksijini efunekayo kwi-oxidation yeentlobo ezincitshisiweyo ezibandakanya izinto eziphilayo, kwisampuli yamanzi usebenzisa i-agent ethile ye-oxidizing, ubushushu kunye nokunciphisa ixesha. Uvavanyo lwe-COD luphawu olungcono longcoliseko lwendalo kumanzi amdaka emizi-mveliso aneecyanides kunye neentsimbi ezinzima. Uvavanyo lwe-COD lunika impendulo ngokukhawuleza kwiimeko eziguqukayo ngaphambi kokuba kuphuhliswe iingxaki ezinzima. Iibhotile ze-COD zikaLovibond ziyahambelana ne-BOTH Lovibond kunye ne-Hach® colorimeters.

I-2mL yesampula yamanzi okanye i-watse yamanzi yongezwa kwi-tube ye-glass ye-16mm yenkcubeko equlethe i-reagent digestion kunye ne-catalyst. I-tube ifakwe i-polypropylene, i-PTFE ifakwe i-cap kwaye ishushu kwi-block digester kwi-150C ngeeyure ze-2. I-chromium ye-Hexavalent e-orenji iyancitshiswa ibe yi-chromium e-greenish trivalent. Uluhlu lokuhlalutya kwindlela ye-spectrophotometric yi-5-150ppm (ilinganiswe kwi-420nm).

Kolu vavanyo kusetyenziswa i-reagent engenanto endaweni yesiqhelo samanzi esingenanto ekubhekiswa kuyo kwimiyalelo yokusebenza yephotometer ngokubanzi. I-reagent blank ilungiswa ngokudibanisa amanzi adityanisiweyo okanye adibeneyo kwi-tube ye-reagent kwaye emva koko ukugaya ityhubhu ngendlela efanayo nesampuli yamanzi.

Iimvavanyo zetyhubhu zohlalutyo lwefotometric ziqinisekisa ngokuphathwa kwazo ngokulula kwaye ke lukhetho lokuqala lwesiqhelo, ilabhoratri kunye nohlalutyo lwenkqubo. Ubuninzi bokuchaneka kunye nokuchaneka kunikezelwe kwiziphumo zokulinganisa ngenxa ye-reagents esele idosi yangaphambili kwi-cuvettes ye-16mm kunye ne-reagents ezongezelelweyo.

I-COD Test Tube yenye yeemveliso eziphambili ze-Aijiren. Iyakwazi ukugqiba iimvavanyo ezininzi ezibalulekileyo, ezifana ne-digestion colorimetry, uvavanyo lomgangatho wamanzi, uvavanyo lwemfuno ye-oxygen, njl njl. I-COD Test Tube eveliswa ngu-Aijiren ine-inertness ephezulu, umgangatho omhle kunye ne-tube ezinzile. U-Aijiren uye waba ngumvelisi owaziwayo we-chromatography yezinto ezisetyenziswayo kumazantsi e-China ngenxa yomgangatho omhle we-COD Test Tube.

I-tube ye-COD ebonelelwe ngu-Aijiren isebenzisa iglasi ekumgangatho ophezulu, engasebenzi kakhulu kwaye ayiyi kusabela ngee-reagents. Ngovavanyo lwe-tube ye-Aijiren COD, ixesha elifunekayo kwinkqubo yokulinganisa lifutshane kakhulu, ngakumbi uhlalutyo oluqhelekileyo kunye nokulinganisa uchungechunge, olunciphisa kakhulu umsebenzi.
I-COD Test Tube yenziwe ngeglasi ye-borosilicate, enokunciphisa utshintsho lwe-pH kunye neengcoliseko ezinokuphuma kwiglasi ye-soda-lime. Ityhubhu yokuvavanya ukwetyisa kweglasi ingasetyenziselwa uhlalutyo kumaqondo obushushu angaphezu kwe-130 degrees Celsius. Yenziwe ngokugcinwa kwebhubhoratri kwiinjongo ezahlukeneyo eziqhelekileyo kwaye inokubamba phantse nantoni na.

Iityhubhu zovavanyo zenzelwe ukumelana namaqondo obushushu aphezulu kunye neekhemikhali eziphendulayo, nto leyo ezenza zilungele uluhlu olubanzi lweemvavanyo kunye nohlalutyo.
Ityhubhu yoVavanyo lwe-COD iqulethe idosi echanekileyo ye-reagent. Ke ngoko, uluhlu olugqithisileyo lweekhemikhali luyaphetshwa kwaye ukhuseleko lomsebenzi luyaphuculwa.

Le ityhubhu yovavanyo lwe-COD yenzelwe ngokuchanekileyo kunye nokusebenza kwengqondo. Ibonisa ulwakhiwo oluqinileyo olunokumelana nobunzima bovavanyo lwe-COD, kubandakanya amaqondo obushushu aphezulu kunye nokuvezwa kweekhemikhali ezahlukeneyo.

I-Aijiren isebenzisa izixhobo ezikumgangatho ophezulu ukwenza iTube yoVavanyo eyi-16mm yoHlalutyo lwaManzi. Ukwaneliseka kwabathengi kunye nendumiso yenze i-Aijiren yaba yenye yezona zinto zithengiswa kakhulu kwilabhoratri kumazantsi eTshayina. Okokuqala, i-Aijiren iya kubambelela injongo yokuqala yokuqinisekisa umgangatho we-16mm Test Tube yokuHlalutya kwamanzi.

Akuyimfuneko ukulungiselela i-reagent engenanto ngexesha ngalinye uvavanyo luqhutywa. I-tube engenanto ye-reagent inokulungiswa ngeveki kwaye isetyenziswe ngokuphindaphindiweyo kunye nazo zonke iisampuli ezilungiselelwe ukusuka kwibhetshi efanayo yeetyhubhu ze-reagent. I-reagent engenanto kufuneka igcinwe ebumnyameni phakathi kokusetyenziswa.
Ukusebenzisa isifudumezi sedijithali kuvavanyo lwe-COD, seta ubushushu kwisiboniso sedijithali ukuya kwi-150°C. Akukho akhawunti kufuneka isifudumezi simiselwe kwiqondo lobushushu elingaphezulu kwelo lichaziweyo njengoko oku kunokubangela ingozi ngokunyuka koxinzelelo kwiityhubhu zeCOD.

I-TOC sisishunqulelo seTotal Organic Carbon. Indlela eNgqo ye-TOC esuka e-Aijiren ibonelela ngeendlela ezithembekileyo nezisebenzayo kumaziko okucoca amanzi ukulinganisa rhoqo i-organic carbon ukuze kuphuculwe iinkqubo zonyango. Esikhundleni sokuthenga i-TOC ebiza kakhulu, i-analyzer yendabuko ye-TOC okanye ukukhutshwa kwe-TOC kwi-laboratory yekhontrakthi, le ndlela inokubonelela ngeziphumo ze-TOC - ngokuchanekileyo nangexabiso eliphantsi - kanye kwindawo yakho, kwaye ngaphandle kwenkunkuma enobungozi.

I-PP cap yenziwe kwisiqwenga esinye esibunjiweyo se-inert, i-polyethylene ekwazi ukumelana neekhemikhali. I-slits ye-starburst ivumela ukungena kwenaliti lula. Iphuhliswe kwizicelo ezinovakalelo oluphezulu, ngakumbi kwiMakethi ye-LCMS, ukucoceka kwesi simboli se-extractable singaphantsi koluhlu lwepicogram. Le polyethylene yomgangatho ophezulu ayinayo imiba yongcoliseko PTFE\/Silicone septa bonisa kumanqanaba asezantsi okubhaqwa, ngelixa ikwatywinwa ngokukhethekileyo.

Imfuno ye-oksijini yemichiza luvavanyo olubalulekileyo lokuvavanya umgangatho wamanzi amdaka kunye namanzi amdaka phambi kokuba alahlwe. Uvavanyo lwe-Chemical Oxygen Demand (COD) luqikelela imfuneko ye-oksijini yamanzi amdaka kwaye isetyenziselwa ukubeka iliso kunye nokulawula ukukhutshwa, kunye nokuvavanya ukusebenza kwezityalo zonyango. Impembelelo yokukhutshwa kwamanzi amdaka okanye asetyenzisiweyo kumanzi afunyenweyo iqikelelwa yimfuno yawo ye-oxygen. Oku kungenxa yokuba ukukhutshwa kweoksijini emanzini endalo kunciphisa amandla ayo okugcina ubomi basemanzini. Uvavanyo lwe-COD ke ngoko lwenziwa njengesiqhelo kwiilabhoratri zamanzi kunye neenkampani zoshishino.
