I-COD yovavanyo lwe-COD ngohlalutyo lwemfuno

I-16mm ityhubhu ye-16mm ye-16 yi-tube ekhethekileyo yeglasi eyenzelwe uvavanyo lweoksijini yeoksijini (i-COD) kwilabhoratri. Inobubanzi be-16mm, ukubonelela ngesithuba esaneleyo sokuqokelelwa kwesampulu kunye nohlalutyo. I-tube yenziwa ngeglasi ekumgangatho ophezulu, ekuqinisekiseni ukuqina kunye nokuhambelana nemilinganiselo echanekileyo ye-COD echanekileyo.

I-Aijiren ibandakanyeka kwimveliso yetyhubhu yovavanyo lwe-COD kunye ne-caps ngaphezulu kweminyaka elishumi, sinolwazi olupheleleyo kunye neenkqubo eziqhelekileyo zokubonisa ityhubhu ye-COD eveliswe yi-aijiren ngexabiso elifanelekileyo.

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.

I-Aijiren COD I-TUBE yenziwa ngeglasi ye-borossilicate, enokunciphisa utshintsho lwe-PH kwaye inokuthi ihlawulwe kwiglasi ye-soda iglasi ..
I-2.0 ml yesisombululo sesampulu yesampulu evela kwi-tube yokuphendula ngaphandle kokuxuba ukuze imilebe mibini eyahlukileyo

I-PP Cap yenziwa kwisiqwengana esinye se-InErt, i-polythylene enganyangekiyo. Izilayidi ze-Starburst zivumela ukungena lula kwenaliti. Ukuphuhliswa kwezicelo zobuntununtunu obungaphezulu, ngakumbi kwimarike ye-LCMs, ukucoceka kwale cap yokukhutshelwa kuphele kuluhlu lwePitogram. Le proothde i-Pealyethylene ayinayo imiba yokungcolisa i-ptfe \ / isiliki sePTA ibonisa imigangatho ephantsi yokufunyanwa, ngelixa ikwatywina kakhulu.

Ityhubhu ye-Aijiren ye-Aijiren ye-Aijiren ye-Aij ityhubhu ye-CD inokuthi ixhotywe ngokutshonayo ngeBhodi yokubhala, elungele ukumakishwa kwepensile. Ikwaxhasa iilogo zesiko. I-COD yovavanyo lwe-CoD eveliswe nge-aijiren inokuba ...

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. 
I-COD esetyenzisiweyo ye-COD iqukethe i-sulfuric acid kunye nezinye iichemicals, ke iiRegents kufuneka ziphathwe ngononophelo. Iziqulatho zombhobho kufuneka zichithwe ngokungqinelana neemfuno zabasemagunyeni.

Kwenziwe kwi-Aijiren yohlobo oluphezulu lomgangatho 1 we-borosililicate iglasi, i-tubes yethu yovavanyo lwe-tube ikhutshelwe i-tops kunye neebhotile ezijikelezileyo. Ezi tubs-screw-rictions eziphezulu zovavanyo eziphezulu zine-415 GPI tes ...

Le tube yovavanyo ye-COD yenzelwe ngokuchanekileyo nangokusebenza engqondweni. Ibonisa ulwakhiwo olunenkani olunokumelana neengqolowa zovavanyo lwe-COD, kubandakanya nobushushu obuphakamileyo kunye nokubonisa iichemicals ezahlukeneyo.

I-tube ye-CoD ebonelelwe yi-Aijiren isebenzisa iglasi ephezulu, eyi-Intert engaphezulu kwaye ayizukusabela ngeerejista. Ngovavanyo lwe-tube ye-Aijiren ye-Aijiren, ixesha elifunekayo lokufumana inkqubo yokulinganisa lifutshane kakhulu, ngakumbi lohlalutyo olusezantsi kunye nokunciphisa umthwalo.

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.

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).

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.
Isetyenziselwe uvavanyo lwamanzi amdaka kaMasipala; Amanzi amdaka omzi-mveliso kunye novavanyo lolawulo lwenkqubo; Uvavanyo lwamanzi okusingqongileyo

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 ukuze inaliti. I-Aijiren yenqanaba le-Aijuls icocwe ngokukodwa kwaye ipakishwe ukunciphisa i-TOC ukuya kumanqanaba asezantsi anokwenzeka, aqinisekise ngemvelaphi ephantsi kuvavanyo lwakho.

Ityhubhu ye-Aijiren Cod incinci ngobukhulu kunye nokukhanya kubunzima. Inokuvavanywa ngaphandle kokuba ezinye izixhobo zelebhu kunye neengcali; Kuthatha kuphela imizuzu engama-3-5 kuphela ukuvavanya isampulu, ngaphandle kwezinto ezongezelelweyo okanye izixhobo, kwaye kulula ukusebenza.

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.

Ityhubhu yovavanyo lweCod yenziwa ngeglasi ye-borossilicate, enokunciphisa utshintsho lwe-PH kunye nongcoliseko olunokukhupha kwiglasi yesoda. Ityhubhu yokugaya iglasi inokusetyenziselwa uhlalutyo kumaqondo obushushu angaphezulu kwe-130 degrees Celsius. Yenziwe ngokutshelwa kwelebhu yeenjongo ezahlukeneyo kwaye kunokubamba nantoni na.
