Ndi mayeso a chubu a Aijiren COD, wogwiritsa ntchito aliyense amatha kuzindikira mosavuta komanso kuzindikira madzi molondola.
Wopangidwa mu Aijiren wagalasi lapamwamba kwambiri la Type 1 la borosilicate, machubu athu oyesera amakhala ndi nsonga zokhala ndi ulusi wozungulira. Machubu oyesa olemetsawa ali ndi 415 GPI thr...
Nthawi yofunikira pakuyezera imafupikitsidwa kwambiri, makamaka pakuwunika kokhazikika ndi kuyeza kwa mndandanda, pomwe kumachepetsa kwambiri ntchito.

Kufunika kwa okosijeni wa Chemical ndichiyeso chofunikira kwambiri pakuwunika kuchuluka kwa zonyansa ndi madzi otayira asanatulutsidwe. Mayeso a Chemical Oxygen Demand (COD) amalosera za oxygen yomwe imafunikira m'madzi otayira ndipo amagwiritsidwa ntchito poyang'anira ndikuwongolera kutayira, ndikuwunika momwe chomera chimagwirira ntchito. Mphamvu ya madzi otayira kapena otayidwa pamadzi omwe akulandira zimanenedweratu ndi kufunikira kwake kwa okosijeni. Zili choncho chifukwa kuchotsedwa kwa okosijeni m’madzi achilengedwe kumachepetsa mphamvu yake yochirikizira zamoyo za m’madzi. Kuyesa kwa COD kumachitidwa ngati chizolowezi m'malo opangira madzi ndi makampani opanga mafakitale.

Mayeso a Chemical Oxygen Demand (COD) amagwiritsidwa ntchito kwambiri ngati muyeso wa kuipitsidwa kwa organic pozindikira kuchuluka kwa okosijeni wofunikira kuti makutidwe ndi okosijeni amitundu yocheperako kuphatikiza zinthu zamoyo, m'chitsanzo chamadzi pogwiritsa ntchito oxidizing agent, kutentha ndi kuchepetsa nthawi. Kuyesa kwa COD ndi chizindikiro chabwino cha zoipitsa organic m'madzi otayidwa m'mafakitale okhala ndi ma cyanides ndi zitsulo zolemera. Kuyesa kwa COD kumathandizira kuyankha mwachangu pakusintha kwamavuto asanachitike.

The COD Test chubu ili ndi mlingo wolondola wa reagent. Chifukwa chake, kuchuluka kwa mankhwala kumapewedwa ndipo chitetezo chantchito chimapangidwa bwino.

Sikuti kukonzekera reagent akusowekapo nthawi iliyonse mayeso ikuchitika. The reagent akusoweka chubu akhoza kukhala okonzeka mlungu uliwonse ndi ntchito mobwerezabwereza ndi zitsanzo zonse anakonza kuchokera mtanda womwewo wa reagent machubu. The reagent akusowekapo ayenera kusungidwa mu mdima pakati ntchito.
Kuyesa kwa machubu pakuwunika kwa photometric kukhutitsidwa ndi kuwongolera kwawo kosavuta, chifukwa chake ndiye chisankho choyamba cha chizolowezi, labotale ndi kusanthula ndondomeko. Kuchuluka kolondola komanso kulondola kumaperekedwa pazotsatira zoyezera chifukwa cha ma reagents omwe adayikidwa kale mu 16mm cuvettes ndi ma reagents owonjezera.

Kuyeza kwa COD ndichizindikiro chabwino cha zinthu zoipitsa organic m'madzi oipa a m'mafakitale okhala ndi ma cyanides ndi zitsulo zolemera. Kuyesa COD kumathandizira kuti zinthu zisinthe msangamsanga mavuto aakulu asanayambe.

Mbalezi nthawi zambiri zimapangidwa ndi galasi lapamwamba kwambiri kapena galasi la borosilicate, lomwe silingagwirizane ndi machitidwe a mankhwala ndipo limatha kupirira kutentha kwakukulu kofunikira pa ndondomeko ya COD. Mbale zapangidwa kuti agwire enieni buku la chitsanzo madzi ndi reagents zofunika kwa COD mayeso.
COD Test Tube imapangidwa ndi galasi la borosilicate, lomwe lingachepetse kusintha kwa pH ndi zonyansa zomwe zimatha kutuluka mu galasi la soda. Chubu choyezera kugayidwa kwa magalasi chingagwiritsidwe ntchito kusanthula kutentha kopitilira 130 digiri Celsius. Amapangidwa ndi malo osungiramo ma labotale pazolinga zosiyanasiyana ndipo amatha kunyamula chilichonse.

Aijiren wakhala akugwira ntchito yopanga COD test chubu ndi Caps kwa zaka zoposa khumi, tili ndi chidziwitso chochuluka komanso njira zomwe timazidziwa bwino popanga chubu choyesera cha COD chokhala ndi kapu, ndipo titha kutsimikiziranso mtundu wa COD test chubu yopangidwa ndi Aijiren ndi mtengo wokwanira.

Ma COD Test Tubes opangidwa ndi Aijiren nthawi zambiri amagwiritsidwa ntchito pozindikira kufunikira kwa oxygen. Galasi yomwe imagwiritsidwa ntchito mu COD Test Tubes yopangidwa ndi Aijiren imakhala ndi kutentha kwambiri, kukana kwa dzimbiri, ndipo imatha kuteteza zitsanzo popanda kukhudza zotsatira zoyesera. Zopangira za Aijiren ndizapamwamba kwambiri komanso zopanga zambiri, zokhala ndi mitengo yabwino yazogulitsa, ndizogulitsa zapamwamba kwambiri zopangira ma chromatographic.

M'njira zambiri, "Test Tube" ingatanthauzenso njira ya YouTube yotchedwa "TestTube," yomwe ndi njira yotchuka ya sayansi ndi maphunziro ya Discovery Digital Networks. Njirayi imakhala ndi mitu yambiri, kuphatikizapo sayansi, luso lamakono, mbiri yakale, ndi chikhalidwe, ndipo imapereka mavidiyo ofotokozera komanso osangalatsa kwa owonera.

2mL ya madzi kapena madzi a watse amawonjezedwa ku chubu la chikhalidwe cha galasi la 16mm lomwe lili ndi digestion reagent ndi chothandizira. Chubucho chimakutidwa ndi polypropylene, kapu ya PTFE yokhala ndi mizere ndikutenthedwa mu chipika cha 150C kwa maola awiri. Chromium ya lalanje ya Hexavalent imachepetsedwa kukhala chromium yobiriwira yobiriwira. Kusanthula kwa njira ya spectrophotometric ndi 5-150ppm (yoyesedwa pa 420nm).

Ndi mayeso a chubu a Aijiren COD, wogwiritsa ntchito aliyense amatha kuzindikira mosavuta komanso kuzindikira madzi molondola. Nthawi yofunikira pakuyezera imafupikitsidwa kwambiri, makamaka pakuwunika kokhazikika ndi kuyeza kwa mndandanda, pomwe kumachepetsa kwambiri ntchito.

Ma COD Tubetes omwe amagwiritsidwa ntchito ali ndi asidi amphamvu a sulfuric ndi mankhwala ena, kotero ma reagents ayenera kusamaliridwa mosamala. Zomwe zili mupaipi ziyenera kutayidwa molingana ndi zofuna za maboma a m'deralo.
