I-16mm ye-16mm ye-16 ye-COD eveliswe yi-Aijiren isetyenziselwa uhlalutyo lweekhompyuter. I-Aijiren ikholelwa ukuba ityhubhu ye-CoD ifuna izinto eziphezulu eziphezulu kunye netekhnoloji ephambili ukugqiba imveliso, ke i-Aijiren inomdla kakhulu kwimveliso yetyhubhu yovavanyo lweCOD. I-Aijiren ibiyigqala kwicandelo le-chromatography enokuthathwa iminyaka engama-20 yamava emveliso. Usagcina injongo yakhe yantlandlolo kwaye ubeka ukuphuculwa komgangatho wemveliso kwindawo yokuqala.

* INKCAZO:

Ityhubhu ye-Aijiren ye-Aijiren ye-Aijiren ye-Aij ityhutyha i-COD ye-OICE inokuthi ixhotyiswe ngokhetho ngebhodi ebhaliweyo, elungele ukumakishwa kwepensile. Ikwaxhasa iilogo zesiko. I-COD yovavanyo lwe-CoD eveliswe nge-aijiren inokuba ...

Ibango leoksijini yeoksijini luvavanyo olubalulekileyo lokuvavanya umgangatho wamanzi amdaka kunye namanzi anqabileyo ngaphambi kokukhutshwa. Uvavanyo lwe-OXYGN WOKUGQIBELA (CoD) vavanya imfuneko efunekayo kwimfuno ye-therighgen ye-Ekrekran kwaye isetyenziselwa ukubeka esweni nokulawulwa kokusebenza kunye nokuvavanya ukusebenza kwezityalo zonyango. Impembelelo yamanzi amdaka okanye amanzi akhutshiweyo amanzi anokufumana amanzi afumanayo axelwe kwangaphambili yimfuno yayo yeoksijini. Kungenxa yokuba ukususwa kweoksijini evela kumanzi endalo kunciphisa amandla ayo okuxhasa ubomi basemanzini. Uvavanyo lwe-COD ke lusenziwa njengenkqubo kwiilebhu zezinto ezisetyenziswayo zamanzi kunye neenkampani zemveliso.

Iityhubhu zovavanyo zeCOD eziveliswa yi-aijiren zihlala zisetyenziselwa iimvavanyo zovavanyo. Olu hlobo lovavanyo luneemfuno eziphezulu zeeTubs zovavanyo ze-COD kwaye zinoluhlu olubanzi lwezicelo. Amayeza, ipetroleum, imichiza, umgangatho wamanzi, njl. Njl. Uvavanyo. Iityhubhu zovavanyo ze-Aiiren ze-Aijiren zinokuhlangabezana neemfuno zezinto ezinokuthengiswa kovavanyo lokugaya.

I-COD yovavanyo lwe-COD yenye yeemveliso eziphambili ze-aijiren. Ingazigqibezela iimvavanyo ezibalulekileyo ezibalulekileyo, ezinjengokugaya i-Deepemilt Livation, uvavanyo lwe-OXYGENT, uvavanyo lwe-OXYGENT, njl. I-Aijiren iye yaba ngumenzi owaziwayo we-chromatographys enokuthethwa emazantsi e-China ngokulunga komgangatho olungileyo wetyhubhu yovavanyo lweCOD.

Kufanelekile ukuba uqaphele ukuba ukuba i-tubetes esetyenzisiweyo inee-tubests ezisetyenzisiweyo ze-sulfuric acid kunye nezinye iikhemikhali, iiRegents kufuneka ziphathwe ngononophelo. Izinto ezenziwe ngemibhobho kufuneka zichithwe ngokungqinelana neemfuno zabasemagunyeni. Ezi tyhubhu zinokusetyenziswa kuphela kwaye azinakuphinda zisetyenziswe.
Ukusebenzisa iheeter yedijithali yovavanyo lwe-COD, setha ubushushu kumboniso wedijithali ukuya kwi-150 ° C. Akukho akhawunti kufuneka i-heater ibekwe kwiqondo lobushushu eliphezulu kunelo elichazwe njengoko oku kunokubangela ingozi kulwakhiwo loxinzelelo kwi-CoD.

Uvavanyo lweemfuno zeoksijini (i-COD) lusetyenziswa ngokubanzi njengomlinganiso we-oxganic ngokumisela ubungakanani obufunekayo kwi-oxygen ye-oxygen kubandakanya iarhente ye-organing, kwi-arhente yamanzi usebenzisa iarhente ethile ye-oxidif, iqondo lobushushu kunye nokuncitshiswa kwexesha. Ukuvavanywa kwe-COD yisalathiso esingcono se-organic sokungcoliseka kwe-organic kumanzi amdaka omzi-mveliso aqukethe i-cyenasides kunye nentsimbi enzima. Uvavanyo lwe-COD lubonelela ngempendulo ekhawulezileyo yokutshintsha kweemeko ngaphambi kokuphuhlisa iingxaki.

2mL of a water or watse water sample are added to a 16mm glass culture tube containing the digestion reagent and a catalyst. Ityhubhu ivalwe nge-polyproplene, i-ptfe ifakwe i-PAYP kwaye ishushu kwibhloko ye-BROGEST nge-150c iiyure ezi-2. I-chromium ye-orenji ye-hextavalent ye-chromium incitshisiwe kwi-chromium eluhlaza. Uluhlu lohlalutyo lwendlela ye-spectraphotometric yi-5-150ppm (ilinganiswe nge-420nm).

Ukuvavanywa kwamanzi kwikhabhoni ye-orbon ye-orbon (i-TOC) ayisasebenzi ishishini lezendalo. Ngeendlela ze-USP zakutshanje, i-TOC ngoku iyinkxalabo ngayo nayiphi na ishishini usebenzisa amanzi acocekileyo kunye namanzi ...

Ukuphinda ufumane ii-CAPS kunye ne-vials Vula ukuba kungenzeka ukuba ungcoliseko, ukusuka kwi-Solvent (i-FILVent (i-Listia okanye i-vapor) inxibelelana ngezinto zeSepta kunye nemozulu. Oku kunokuba nefuthe elikhulu kwiziphumo zakho zohlalutyo, oonobangela luphawu lwesampulu, ukuphendula kwamachiza, okanye ukuvela. Zombini iimpazamo zenqanaba kunye nobungakanani zinokubangela, zifuna ixesha lokutya, ukubiza kakhulu, nokugungqa iingxaki kunye nokusebenza kwakhona.
Emva kwe-2 h Susa ityhubhu yovavanyo kwibhloko yokufudumeza, vumela ukuba uphole kubushushu begumbi kwaye shala ngobunono

I-Aijiren isebenzisa izixhobo ezikumgangatho ophezulu ukwenza ityhubhu yovavanyo lwe-16mm yohlalutyo lwamanzi. Ukoneliseka kwabathengi kunye nokudunyiswa kwenze i-Aijiren yenye yezona zinto zininzi zelebhoratri ezinokuthengiswa kwelebhu emazantsi eTshayina. Okokuqala, i-Aijiren izakunamathela injongo yoqobo ukuqinisekisa ukuba umgangatho we-16mm yovavanyo lohlalutyo lwamanzi.

I-Aijiren COD I-TUBE yenziwa ngeglasi ye-borossilicate, enokunciphisa utshintsho lwe-PH kunye nokungcoliseka okunokuthi kuhlawulwe kwiglasi yesoda.  I-tube yokuganga kweglasi inokusetyenziselwa uhlalutyo ...

Iityhubhu zovavanyo zeCOD eziveliswa nge-aijiren zihlala zisetyenziselwa imfuno yokufunwa kweoksijini. Iglasi isetyenziswe kwiiTubs zovavanyo lwe-CoD eziveliswa yi-Aijiren inamaqondo obushushu obushushu, ukuxhathisa ubuchule, kwaye kungazikhusela iisampulu ngaphandle kokuchaphazela iziphumo zovavanyo. Izinto ezingafunekiyo ze-Aijiren zikumgangatho ophezulu kunye nolwalamano oluninzi, oluhle ngexabiso lemveliso, ngumthengisi owona mgangatho uphambili we-chromatographic enokuthengiswa.

Ukuvavanywa kwe-COD yisalathiso esingcono se-organic sokungcoliseka kwe-organic kumanzi amdaka omzi-mveliso aqukethe i-cyenasides kunye nentsimbi enzima. Uvavanyo lwe-COD lubonelela ngempendulo ekhawulezileyo yokutshintsha kweemeko ngaphambi kokuphuhlisa iingxaki.
