Iyunithi yokuthengisa ilori iyathengiswa

Kwingqondo ebanzi, "ityhubhu yovavanyo" inokubhekisa kwi-YouTube Channel ebizwa ngokuba yi "vavanyo," enguMjelo weSayensi odumileyo kunye nomjelo wezemfundo ngenethiwekhi yedijithali. Ijelo ligubungela uluhlu olubanzi lwezihloko, kubandakanya nesayensi, itekhnoloji, imbali kunye nenkcubeko, kwaye ibonelela ngeevidiyo ezinolwazi kunye nokuzonwabisa iividiyo zababukeli.
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.

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.

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).
* INKCAZO:

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-cod diegs i-vills i-vials zikhohlakele ezisetyenzisiweyo kuhlalutyo lweekhemikhali zokumisela imfuno yeoksijini yeoksijini (i-COD) yesampulu yamanzi. I-COD ngumlinganiso wenani leoksijini efunekayo ekufumaneni izikhephe ze-sporganic kunye ne-inorganic machie ekhoyo emanzini.

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.

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.

Uvavanyo lwe-Tube lohlalutyo lwe-thongtric uqiniseka ngokuphatha ngokulula kwaye ke lukhetho lokuqala lwendlela, elebhu kunye nohlalutyo lwenkqubo. Ubuninzi bokuchaneka kunye nokuchaneka kunikezelwa ngenxa yeziphumo zomlinganiso ngenxa yeeregents zangaphambili kwi-16mm Cupettes kunye ne-regeents eyongezelelweyo.

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.

I-16mm ityhubhu ye-16MM

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.

Uvavanyo lwetyhubhu ligama elinokubhekisa kwizinto ezahlukeneyo ngokuxhomekeke kwimeko. Kwimeko yesayensi, ityhubhu yovavanyo yiglasi ye-cylindrical okanye ityhubhu yeplastiki esetyenziselwa ukubamba kwaye idibanise izixa ezincinci zolwelo ngexesha lovavanyo kwiilebhu. Ihlala isetyenziswa kwi-chemistry, yebhayoloji, kunye nezinye iindlela zenzululwazi.
Ezi vils ziqhele okwenziwa ngeglasi ekumgangatho ophezulu okanye iglasi ye-borosilicate, engaxhakisi ukuphendula kweekhemikhali kwaye inokumelana namaqondo obushushu aphezulu ayimfuneko kwi-CoD Depenity Inkqubo yokugaya i-CoD. Iiphenyi zenzelwe ukubamba ivolumu ethile yesampulu yamanzi kunye neeRegents eziyimfuneko kuvavanyo lweCOD.

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 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.

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. I-lovibond's cods i-cods ihambelana nayo zombini imibala ye-lovibond kunye ne-hach ®.

I-Aijiren COD I-COD yenziwe ngeglasi ye-borossilicate, enokunciphisa iinguqu ze-PH kunye ne-Pillbals ezinokuthi zibhalwe kwiglasi ye-soda.

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.

Iityhubhu zovavanyo ze-Aijiren zisetyenziswa kwisixhobo sokugaya abantu

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.
