COD chubhu

Kudiwa kwemakemikari okisijeni muyedzo wakakosha wekuongorora mhando yemvura inoyerera uye tsvina isati yaburitswa. Muedzo weChemical Oxygen Demand (COD) unofanotaura zvinodikanwa zveokisijeni mutsvina uye inoshandiswa pakutarisa nekudzora zvinobuda, uye kuongorora mashandiro echirimwa. Mhedzisiro yekuyerera kwetsvina kana tsvina yemvura pamvura inotambirwa inofanotaurwa nekudiwa kwayo kweokisijeni. Izvi zvinodaro nekuti kubviswa kweokisijeni kubva mumvura yakasikwa kunoderedza kugona kwayo kuchengetedza hupenyu hwemumvura. Kuongorora kweCOD kunoitwa senguva dzose mumarabhoritari ezvemvura nemakambani emaindasitiri.

Aijiren COD Test Tube idiki mukukura uye yakareruka mukurema. Inogona kuedzwa pasina chero mimwe michina yerabhoritari uye matekiniki; zvinongotora 3-5 maminetsi kuyedza sampuli, pasina zvimwe zvekushandisa kana zviridzwa, uye iri nyore kushanda.

COD testing chiratidzo chirinani chezvinosvibisa zvinosvibisa mumaindasitiri mvura ine tsvina ine macyanides nemasimbi anorema. Kuongorora kweCOD kunopa mhinduro nekukurumidza kumamiriro ekuchinja kusati kwaitika matambudziko akanyanya.

Kuyedzwa kweCOD chiratidzo chirinani chekusvibisa organic mumvura yetsvina yemaindasitiri ine cyanides uye zvinorema simbi. Kuyedzwa kweCOD kunopa mhinduro nekukurumidza kune shanduko yemamiriro ezvinhu asati atanga matambudziko akakomba. 

Iyo COD Test Tube yakagadzirwa negirazi yeborosilicate, iyo inogona kuderedza pH shanduko uye zvinosvibisa zvinogona kubuda kunze kwesoda-lime girazi. Iyo girazi digestion test chubhu inogona kushandiswa kuongororwa patembiricha yakakwira kupfuura 130 degrees Celsius. Yakagadzirwa nekuchengetedza marabhoritari kune zvakasiyana-siyana zvezvinangwa uye inogona kubata chero chinhu.

COD Test Tube ndeimwe yezvigadzirwa zvikuru zveAijiren. Inogona kupedzisa kuedza kwakakosha kwakawanda, senge digestion colorimetry, bvunzo yemhando yemvura, bvunzo yeoxygen inoda, etc. Iyo COD Test Tube inogadzirwa neAijiren ine inertness yakakwirira, yakanaka kunaka uye yakagadzikana chubhu. Aijiren yave mugadziri anozivikanwa wechromatography consumables kumaodzanyemba kweChina nekuda kwemhando yakanaka yeCOD Test Tube.

Iyo COD Test Tube inogadzirwa naAijiren inowanzo shandiswa mumakemikari ekudiwa kweokisijeni. Sezvo kemikari yeokisijeni inoda bvunzo iri bvunzo inoda mareagents akasimba ekuora, Aijiren inoshandisa yakanyanya inert uye yakagadzikana girazi kugadzira COD Test Tube, iyo inogadzirwa neAijiren. COD Test Tube inosangana nezvinodiwa nevatengi pakuyedzwa kwekudiwa kweokisijeni.

Muyedzo iyi reagent isina chinhu inoshandiswa pachinzvimbo chemvura yakajairwa isina chinhu inotaurwa mune yakajairika photometer yekushandisa mirayiridzo. Iyo reagent isina chinhu inogadzirwa nekuwedzera deionised kana distilled mvura kune reagent chubhu uye ipapo kugaya chubhu nenzira yakafanana neyeyemvura sampuli.
Izvo hazvifanirwe kugadzirira reagent isina chinhu pese panoitwa bvunzo. Iyo reagent isina chubhu inogona kugadzirirwa vhiki nevhiki uye inoshandiswa kakawanda nemasampuli ese akagadzirwa kubva kune imwechete batch reagent machubhu. Iyo reagent isina chinhu inofanira kuchengetwa murima pakati pekushandisa.

Iyo yakashandiswa COD Tubetests ine yakasimba sulfuric acid uye mamwe makemikari, saka reagents inofanirwa kubatwa nemazvo. Zviri mupombi zvinofanira kuraswa maererano nezvinodiwa nevakuru venzvimbo.
Aya machubhu ebvunzo ane SGC anosimbiswa. Aya machubhu anogona kushandiswa kamwe chete, saka haagone kushandiswa zvakare.

Kuti ushandise hita yedhijitari pabvunzo yeCOD, isa tembiricha padhijitari kuratidza kusvika 150°C. Hapana chikonzero kuti hita inofanira kuiswa patembiricha yepamusoro kupfuura iyo yataurwa sezvo izvi zvichigona kukonzera njodzi kuburikidza nekumanikidza kuvaka-up mumachubhu eCOD.

Inokodzera colorimeters uye test kits pamusika
Uyewo akakodzera zviridzwa uye test kits
Zvirinyore-ku-kuvhurika zvakavharwa mabhodhoro anobvisa njodzi yekukanganiswa-kusvibiswa
Wedzera hupenyu hwesherufu kusvika kumakore mashanu
Inoshandiswa pakuongorora mvura yetsvina yekanzuru; indasitiri yetsvina yemvura uye maitiro ekudzora maitiro; kuongororwa kwemvura yezvakatipoteredza

Vhura COD test chubhu, ibate pakona uye wowedzera zvishoma nezvishoma
2.0 mL ye pretreated sampuli mhinduro kubva kune reaction chubhu pasina kusanganisa kuitira kuti maviri akaparadzana akaturikidzana
zvinoumbwa.
Kavha kepu yakachengeteka kuti uedze chubhu, bata chubhu nekavha, isa chubhu mubhodhoro rekuchengetedza uye zunza
(Kuchenjerera, test tube inopisa). Isa chubhu mumudziyo wekudziya. Tanga kudziyisa purogiramu.
Mushure memaawa maviri bvisa test tube kubva pakupisa block, bvumira kutonhora kusvika kukamuri tembiricha uye zunza zvinyoro
kakawanda.
Chenesa kunze kwechubhu yebvunzo uye kuyera.
Gadzirisa photometer kusvika zero nekushandisa isina chinhu kukosha "NULL"

Kudiwa kwemakemikari okisijeni muyedzo wakakosha wekuongorora mhando yemvura inoyerera uye tsvina isati yaburitswa. Muedzo weChemical Oxygen Demand (COD) unofanotaura zvinodikanwa zveokisijeni mutsvina uye inoshandiswa pakutarisa nekudzora zvinobuda, uye kuongorora mashandiro echirimwa. Mhedzisiro yekuyerera kwetsvina kana tsvina yemvura pamvura inotambirwa inofanotaurwa nekudiwa kwayo kweokisijeni. Izvi zvinodaro nekuti kubviswa kweokisijeni kubva mumvura yakasikwa kunoderedza kugona kwayo kuchengetedza hupenyu hwemumvura. Iyo COD bvunzo saka inoitwa semazuva ese mumarabhoritari ezvemvura zvinoshandiswa nemakambani emaindasitiri.

NeAijiren COD chubhu bvunzo, mushandisi wega wega anogona kuita nyore kuona uye kuona kwemvura kwakaringana.
Iyo nguva inodiwa yekuyera maitiro inopfupikiswa zvakanyanya, kunyanya kuongororwa kwakajairwa uye kuyerwa kwakatevedzana, uku ichideredza zvakanyanya basa.
Iyo COD Yekuyedza chubhu ine chaiyo dosi reiyo reagent. Naizvozvo, yakawandisa kemikari inventory inodziviswa uye kuchengetedzwa kwebasa kunovandudzwa.

Muedzo weChemical Oxygen Demand (COD) unoshandiswa zvakanyanya sechiyero chekusvibiswa kwehupenyu kuburikidza nekuona huwandu hweokisijeni hunodiwa pakuita oxidation yemhando dzakaderedzwa dzinosanganisira organic matter, mumucherechedzo wemvura uchishandisa imwe oxidizing agent, tembiricha uye kuderedza nguva. Kuyedzwa kweCOD chiratidzo chirinani chekusvibisa organic mumvura yetsvina yemaindasitiri ine cyanides uye zvinorema simbi. Kuyedzwa kweCOD kunopa mhinduro nekukurumidza kune shanduko yemamiriro ezvinhu asati atanga matambudziko akakomba. Lovibond's COD vials inoenderana neBOTH Lovibond uye Hach® colorimeters.

Tube bvunzo dzekuongororwa kwephotometric dzinogutsikana nekubata kwavo nyore uye saka ndiyo yekutanga sarudzo yemaitiro, marabhoritari uye maitiro ekuongorora. Iyo yakawanda mukurongeka uye nemazvo inopihwa kune kuyerwa kwemhedzisiro nekuda kweiyo pre-dosed reagents mu16mm cuvettes uye mamwe mareagents.

Kuedza mvura yeTotal Organic Carbon (TOC) haichave yakasarudzika kune indasitiri yezvakatipoteredza. Neazvino USP nzira, TOC yave kunetseka kune chero indasitiri inoshandisa Yakanatswa Mvura uye Mvura Yejekiseni. Aijiren Yakaderera Level TOC Vials yakanyatsocheneswa uye yakarongedzwa kudzikisa TOC kune yakaderera mazinga anogoneka, ichivimbisa yakaderera kumashure kwekuyedzwa kwako.

TOC ndiyo pfupiso neTotal Organic Carbon. Iyo TOC Direct Method kubva kuAijiren inopa yakavimbika uye inoshanda nzira dzekuti nzvimbo dzekurapa mvura dzigare dzichiyera organic kabhoni kuti ikwidze maitiro ekurapa. Panzvimbo pekutenga inodhura, yechinyakare TOC analyzer kana kuendesa kunze zvakatemerwa TOC kune kondirakiti laboratori, nzira iyi inogona kupa TOC mhinduro - nemazvo uye zvisingadhure - panzvimbo yako chaipo, uye pasina chero tsvina ine ngozi.

Aijiren yave ichiita kugadzirwa kweCOD test chubhu neCaps kwemakore anopfuura gumi, tine ruzivo rwakanyanya uye maitiro akajairwa kugadzira COD test chubhu ine cap, uye tinogona kuvimbisa mhando yepamusoro yeCOD test chubhu inogadzirwa neAijiren nemutengo unonzwisisika.

Aijiren inoshandisa zvemhando yepamusoro mbizha kugadzira 16mm Test Tube yeKuongorora Mvura. Kugutsikana kwemutengi uye kurumbidza kwakaita kuti Aijiren ive imwe yevagadziri vakakura murabhoritari zvigadzirwa kumaodzanyemba kweChina. Chekutanga, Aijiren inonamatira yepakutanga chinangwa chekuva nechokwadi chemhando ye16mm Test Tube yeKuongorora Mvura.
