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 lweCOD ke ngoko lwenziwa njengesiqhelo kwiilabhoratri zamanzi kunye neenkampani zoshishino.

Ngengqiqo ebanzi, "iTube yoVavanyo" inokubhekisa nakwijelo likaYouTube elibizwa ngokuba yi "TestTube," isijelo esidumileyo sesayensi kunye nemfundo ephethwe yiDiscovery Digital Networks. Ijelo ligubungela uluhlu olubanzi lwezihloko, kubandakanya isayensi, itekhnoloji, imbali, kunye nenkcubeko, kwaye ibonelela ngeevidiyo ezifundisayo nezokonwabisa ababukeli.

I-Aijiren COD Test Tube yenziwe ngeglasi ye-borosilicate, enokunciphisa utshintsho lwe-pH kunye nezingcolisi ezinokutsalwa kwiglasi yekalika yesoda. Ityhubhu yokuvavanya ukwetyisa kweglasi ingasetyenziselwa uhlalutyo ...

Kuyafaneleka ukuba uqaphele ukuba ukuba i-COD Tubetests esetyenzisiweyo iqulethe i-asidi ye-sulfuric eqinile kunye nezinye iikhemikhali, i-reagents kufuneka iphathwe ngokucophelela. Izinto ezikwipayipi kufuneka zilahlwe ngokuhambelana neemfuno zabasemagunyeni basekhaya. Le mibhobho ingasetyenziswa kube kanye kwaye ayinakuphinda isetyenziswe.

U-Aijiren uye wabandakanyeka kwimveliso ye-COD test tube kunye ne-Caps iminyaka engaphezu kweshumi, sinamava atyebileyo ngokupheleleyo kunye neenkqubo eziqhelekileyo zokuvelisa ityhubhu yokuvavanya i-COD ene-cap, kwaye sinokuqinisekisa umgangatho ophezulu we-COD yokuhlola ityhubhu eveliswa ngu-Aijiren ngexabiso elifanelekileyo.

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.

I-COD Tubetests esetyenzisiweyo iqulethe i-asidi eqinile ye-sulfuric kunye nezinye iikhemikhali, ngoko ke ii-reagents kufuneka ziphathwe ngononophelo. Iziqulatho zombhobho kufuneka zilahlwe ngokuhambelana neemfuno zamagunya asekuhlaleni.

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. <\/p>

Iingqayi zeCOD zokwetyisa zizikhongozeli ezikhethekileyo ezisetyenziswa kuhlalutyo lwekhemikhali ukuze kubonwe imfuno yemichiza yeoksijini (COD) yesampulu yamanzi. I-COD ngumlinganiselo wobungakanani beoksijini efunekayo kwikhemikhali i-oxidize i-organic and inorganic compounds ekhoyo emanzini.
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.

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.

Uvavanyo lweCOD ke ngoko lwenziwa njengesiqhelo kwiilabhoratri zamanzi kunye neenkampani zoshishino.

Uvavanyo lweTube ligama elinokuthi libhekiselele kwizinto ezahlukeneyo ngokuxhomekeke kumxholo. Kwimeko yenzululwazi, ityhubhu yovavanyo yiglasi ecylindrical okanye ityhubhu yeplastiki esetyenziselwa ukubamba kunye nokuxuba ulwelo oluncinci ngexesha lovavanyo kwiilabhoratri. Isetyenziswa ngokuqhelekileyo kwi-chemistry, biology, kunye nezinye iinkalo zenzululwazi.

I-COD Test Tube eveliswe ngu-Aijiren inomthamo we-10ml, 12ml, kunye ne-15ml. Umgangatho yi-16mm. Ihlala isetyenziselwa uvavanyo lomgangatho wamanzi kwaye iqulethe iirejenti zolwelo. Isetyenziswa kakhulu kwishishini lepetroleum kunye nohlalutyo lweekhemikhali.

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.

Yenziwe kwi-Aijiren yodidi oluphezulu lweglasi ye-borosilicate yeglasi, iibhubhu zethu zokuvavanya zibonisa imisonto ephothiweyo kunye nezantsi ezijikelezileyo. Ezi tyhubhu zovavanyo ezisindayo zine-415 GPI thr...

Amanzi okuvavanya iTotal Organic Carbon (TOC) awasekho kushishino lokusingqongileyo kuphela. Ngeendlela zamva nje ze-USP, i-TOC ngoku ixhalabile kuyo nayiphi na imboni esebenzisa Amanzi acocekileyo kunye naManzi okuTofa. IiVials ze-TOC ze-Aijiren eziphantsi zicocwa ngokukodwa kwaye zipakishwe ukunciphisa i-TOC ukuya kumanqanaba aphantsi kunokwenzeka, ukuqinisekisa imvelaphi ephantsi yovavanyo lwakho.
