mtengo wa cod test tube

16mm COD Test Tube ndi chubu lagalasi lapadera lopangidwira kuyesa kwa Chemical Oxygen Demand (COD) mu labotale. Ili ndi mainchesi a 16mm, yopatsa malo okwanira kusonkhanitsa ndi kusanthula zitsanzo. Chubucho chimapangidwa ndi galasi lapamwamba kwambiri, kuwonetsetsa kukhazikika komanso kuyanjana kwamankhwala pamiyezo yolondola komanso yodalirika ya COD.

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 chifukwa chake kumachitidwa monga mwachizolowezi m'ma laboratories a zamadzi ndi makampani amakampani.

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 amapanga COD Test Tube poyesa madzi. COD Test Tube itha kugwiritsidwanso ntchito pazida zosiyanasiyana zowunikira. Chifukwa kusanthula kumafuna kutentha, ma reagents mu COD Test Tube amafunikira kutentha kwapamwamba kapena mphamvu zina zamakemikolo, zomwe zimakhudza mtundu wagalasi. Ndi zofunika kwambiri, Aijiren amagwiritsa ntchito galasi la inert lapamwamba kwambiri kuti apange COD Test Tube, yomwe imathandizira kuti pakhale zochitika za mankhwala.

Ma COD Test Tubes opangidwa ndi Aijiren nthawi zambiri amagwiritsidwa ntchito poyesera digestion colorimetric. Kuyesera kwamtunduwu kuli ndi zofunikira kwambiri pa COD Test Tubes ndipo kumakhala ndi ntchito zambiri. Mankhwala, mafuta, mankhwala, khalidwe la madzi, etc. onse ayenera kugwiritsa ntchito chimbudzi colorimetric kuyesa. kuyesa. Machubu Oyesa a Aijiren a COD amatha kukwaniritsa zofunikira pazakudya pakuyesa kwamtundu wa digestion.

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.

Pachiyeso ichi, reagent yopanda kanthu imagwiritsidwa ntchito m'malo mwa madzi omwe alibe kanthu omwe amatchulidwa mu malangizo ogwiritsira ntchito photometer. The reagent akusowekapo anakonza ndi kuwonjezera deionised kapena osungunulidwa madzi kwa reagent chubu ndiyeno kugaya chubu chimodzimodzi monga madzi chitsanzo.
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.

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

Tsatanetsatane wa Mayeso a Chemical Oxygen Demand:

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).

Ma COD Tubetests omwe amagwiritsidwa ntchito ali ndi sulfuric acid ndi mankhwala ena, kotero ma reagents ayenera kusamaliridwa mosamala. Zomwe zili mupaipi ziyenera kutayidwa malinga ndi zofunikira za akuluakulu a boma.
Machubu oyesera awa ndi ovomerezeka a SGC. Machubuwa atha kugwiritsidwa ntchito kamodzi kokha, kotero sangathe kugwiritsidwanso ntchito.

Kuti mugwiritse ntchito chotenthetsera cha digito poyesa COD, ikani kutentha pa chiwonetsero cha digito kufika 150°C. Palibe chifukwa chotenthetsera chotenthetsera chapamwamba kuposa chomwe chatchulidwa chifukwa izi zingayambitse ngozi chifukwa cha kuchuluka kwa mphamvu mu machubu a COD.

Oyenera ma colorimeter ndi zida zoyesera pamsika
Komanso oyenera zida ndi zida mayeso
Zosavuta kutsegula Mbale zomata zimachotsa chiopsezo cha kuipitsidwa
Wonjezerani moyo wa alumali mpaka zaka zisanu
Amagwiritsidwa ntchito poyesa madzi onyansa a tauni; Kuyesa kwamadzi otayira m'mafakitale ndi kuwongolera njira; kuyesa madzi zachilengedwe

Tsegulani chubu choyesera cha COD, igwireni pakona ndikuwonjezera pang'onopang'ono
2.0 mL wa pretreated chitsanzo njira kuchokera anachita chubu popanda kusakaniza kuti awiri osiyana zigawo
Kugwiritsa ntchito
Pewani kapu mosamala kuti muyese chubu, gwira chubu ndi kapu, ikani chubu mu botolo lachitetezo ndikugwedezani
(Chenjezo, chubu choyesera chimakhala chotentha). Ikani chubu mu chotenthetsera chipika. Yambani pulogalamu yotenthetsera.
Pambuyo pa 2 h chotsani chubu choyezera pa chotenthetsera chotenthetsera, lolani kuti chizizire mpaka kutentha ndikugwedezani pang'ono
Botolo la Reagent
Yesani kunja kwa chubu choyesera ndi kuyeza.
Sinthani chithunzithunzi kukhala ziro pogwiritsa ntchito mtengo wopanda kanthu "NULL"

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.

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

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. Mbale za COD za Lovibond zimagwirizana ndi BOTH Lovibond ndi Hach® colorimeters.
