Makemikari okisijeni okisijeni. Aya machubhu akakosha akagadzirirwa kumira kuti germes of the cod kuyedza maitiro, ayo anosanganisira kuyera huwandu hweokisijeni raida kuitira makemikari oxidize organizer nyaya mune yemvura. Ichi chinyorwa chinoongorora basa racho, kuvaka, uye zvikumbiro zveCod tubes, zvichiratidza kukosha kwavo mukurapwa kwezvakatemerwa nemamiriro ekunze uye kurwiswa kwematambudziko.

Kuti uwane rumwe ruzivo nezve cod test tubes uye zvavanoshandisa mukuongororwa kwemvura, kureva chinyorwa ichi: "Sei iyo COD bvunzo tube inoshandiswa mukuongororwa kwemvura."

Kunzwisisa makemikari okisijeni kudiwa (cod)

Cod ndiyo kiyi paramende yakashandiswa kuongorora iyo nhanho yeiyo organic kusvibiswa mumuviri wemvura. Zvinoyera huwandu hweokisijeni hunogadzirwa apo zvese organic makomputa mune sampuli ari oxidized neine yakasimba oxidant (kazhinji potassium dichromate) pasi pemamiriro ezvinhu ezvinyorwa. Maitiro eCodhi anogona kupa nzwisiso inogona kuitika pamatanho ezvematanda ezvematare, sekukatyamadza kwepamhepo kunogona kukonzera kuderera kweokisijeni mumvura, izvo zvinogona kukanganisa hupenyu hwemumvura.

Kuvakwa kweCOD bvunzo tubes

Cod test tubesinonyanya kugadzirwa kubva kuBoorosilrate girazi, inozivikanwa nekuda kwekurwisa kwayo kwemakemikari uye makemikari. Izvi zvinhu zvakakosha sezvo maitiro ekugaya anoda kupisa samples kusvika anenge 150 ° C kwemaawa maviri. MaTubes emuedzo akakodzera ne screw-cap kuvheneka ayo anowanzo tarisa ptfe \ / Silicone septum kudzivirira kubhururuka uye kusvibiswa panguva yekugaya.

ZVINOKOSHA ZVINOKOSHA

Zvinyorwa: Borosilrate girazi inovimbisa kusimba uye kuramba kuimba yekudyara uye yemakemikari kuronga.

Dhizaini: Iyo screw-cap dhizaini inobvumira kusimbisa chisimbiso panguva yakakwirira-tembiricha yekugaya.

Saizi Kusiyanisa: CoD Test Tubes inouya muhukuru hwakasiyana-siyana kuti dziwane masaga akasiyana, kubva kuderera (3-150 mg "/ l) kusvika kumusoro (200-15,000 mg" / l) organts.

Maitiro ekugaya

Iyo COD kuyedza maitiro inosanganisira matanho anoverengeka ekutsamwa:

Sampula Kugadzirira: Muenzaniso wemvura unounganidzwa uye wakachengetedzwa neslfuric acid kuti udzikise iyo organiz.

Aciquiting: Bhuku rakayerwa (kazhinji 2 mL) yemuenzaniso unoendeswa mune yekutanga-yakagadzirirwa cod test test tub.

Kugaya:Iyo bvunzo tubeinoiswa muCOD Setic yakaiswa kusvika ku150 ° C kwemaawa maviri. Pakati peino nguva, iyo organic nyaya ndeye oxidized ne potasium dichromate munzvimbo yemamiriro ekunze.

Kuyerwa: Mushure mekufa, iyo mhinduro yekugadzirisa inoyerwa uchishandisa spectrophotometer pane chaiyo wavelengths (kazhinji ichitenderedza mazana matanhatu) kuti uzive kusunganidzwa kweiyo oxidized organic zvinyorwa.

Iyi nzira inobvumidza yekuongorora nekukurumidza kwehunhu hwemvura uchienzaniswa ne biochemical oxygenicial fanicgen

Unoda kuziva zvakawanda nezve cod test tube, ndapota tarisa chinyorwa ichi:COD bvunzo tube ne pp screw cap yekuongorora kwemvura

Zvikumbiro zveCOD bvunzo tubes

1. Kubata kwemarara

Muzvivakwa zvekurapa zvekurapa Nekuyera iyo cod mazinga isati yatanga uye mushure mekurapwa, vashandisi vanogona kuongorora kana nzvimbo yacho ichizisa inobvisa organic pollutants kubva kumarara. Ruzivo urwu rwakakosha pakururamisa kurapwa maitiro uye kuona kutevedzera nemitemo yezvakatipoteredza iyo inotaura zvinogamuchirwa discharge.

2. Kuongorora Kwepomberedza

Masangano ezvemamiriro ekunze anoshandisa cod kuongororwa kuti aongorore mhando yemvura mumhiko, nyanza, uye mamwe miviri yemvura. Kugara uchiedza kunobatsira kuziva masosi ekusvibisa uye ongorora hutano hwezvisikwa kwenzvimbo dzekutengesa. Yakakwira cod mazinga inogona kuratidza kusvibiswa kubva kuindasitiri kubva kuindasitiri kana kumhanya kubva kune zviitiko zvekurima, zvichiita kuti uwedzere kuferefetwa uye kugadzirisa basa.

3. Regulatory kutevedzera

Zvizhinji zvinosungwa zvine miganho yekudzora miganhu ye cod mazinga mune yakaratwa marara kuti udzivirire equitic ecosystems. Nekuitisa nguva dzose COD bvunzo uchishandisa nzira dzakarongeka dzichishandisa nzira dzakaenzana tubes tubes, zvidyarwa zvekurapa zvinogona kuratidza kutevedzera mitemo iyi uye kudzivisa kuwana faindi kana kuita zviri pamutemo.

4. Kutsvaga uye Kubudirira

Mune zvedzidzo uye maindasitiri ekutsvaga marongero,Cod test tubesvanoshandirwa muzvidzidzo zvakanangwa pakukudziridza mutsva wemagetsi tema tekinoroji kana kunzwisisa organic kusvibisa maitiro munzvimbo dzakasiyana siyana. Kuyera kwakakwana kweCod kwakakosha kuti uongorore nzira nyowani dzekurapa kana kuenzanisa sarudzo dzakasiyana dzekurapwa.

Maitiro akanakisa ekushandisa cod test tubes

Kuve nechokwadi chechokwadi mhedzisiro kana uchishandisaCod test tubes, zvakakosha kutevedzera zvakanakisa maitiro:

Kusvibisa kudzivirira: Ita shuwa kuti midziyo yese yakachena uye yakasununguka kubva kuchimisikidzwa usati washandisa.

Kubata Kwakakodzera: Shandisa Zvakakodzera Zvivakwa Zvekudzivirira Kwemunhu (PPE) paunenge uchibata dzinza zvine hazardous rine mukati memabhuru bvunzo.

Calibration: inogara calibrate spectrophotric michina inoshandiswa pakuyera kubata kuchengetedza kuchengetedza kurongeka.

Tevera mirayiridzo yemigadziri: kuomerera zvakanyanyisa kune nhungamiro dzakapihwa nevanogadzira maererano nekugadzirira kwemapepa, kuchera nguva, uye tembiricha yekugadzirisa.

Mhedziso

Cod test tubeschishandiso chakakosha mukuongororwa kwezvakatipoteredza, kupa data rakakosha pamvura yemvura uye mazinga ekusvibisa. Danho ravo rakasvibirira rinovabikisa kuti vasiye mamiriro ezvinhu anoedza paunenge uchipa zviyero zvakaringana zvinokoshesesa kumanzvimbo zvinobudirira manejimendi uye kudzivirirwa kwezvakatipoteredza. Semitemo ine chekuita nemvura inowedzera kuwanda, kuongororwa kweCOD kucharamba kuchingoenderera mberi nekutamba kwakakosha mukudzivirira maAquitic ecosystems uye hutano hweveruzhinji kuburikidza nesarudzo dzeveruzhinji dzakavakirwa pane yakavimbika data.

Kunzwisisa kwakadzama kwekuti coD vials anoshanda mukuedzwa kwemvura, ndapota tarisa kuchinyorwa ichi: "Iyo inoshanda nheyo ye cod vial."
