Cemical oxygen inodikanwa (cod) ndiyo nzira yakakosha yekuongorora mhando yemvura kubva kune dzakasiyana siyana dzemvura dzemvura, kusanganisira nzizi, dzinza, uye zvirimwa zvine marara. COD matanho huwandu hweokisijeni hunodiwa kuti makeme oxidize organic makomputa mumvura, izvo zvinogona kuratidza huwandu hwekusvibiswa chiripo. Kushandisa zvinobudirira kweCOD bvunzo tubes kwakakosha kuti uwane mibairo chaiyo uye yakavimbika. Iyi blog ichakutungamira mukushandiswa kwakakodzera kweCOD bvunzo tubes yemvura yekuyedza, kusanganisira kugadzirira, maitiro, uye maitiro akanakisa.

Cod test tubesdzakanyatsogadzirwa girazi kana mapurasitiki emapurasitiki materu ane matanho ekutanga-akaenzana reagents yeCOD ongorora. Iyi tubs tubs inowanzo shandiswa neyemmetric ongorora masisitimu ekunyatsoona cod mumatura emvura. Muedzo wakavakirwa pane zvakaitwa neiyo organic nyaya neine yakasimba oxidizing mumiririri, kazhinji potassium dichromate, mune mhinduro ye acidic.

Iwe unoziva here kushandiswa kweCOD bvunzo machubhu mumvura kuongorora? Ndokumbirawo kuti muverenge chinyorwa ichi: Maitiro eCOD bvunzo tube inoshandiswa mukuongororwa kwemvura

ZVINOKOSHA ZVINOKOSHA zveCOD bvunzo tubes

Pre-yakayerwa Reagents: CoD Test Tubes inouya nePre-Paired Reagents, kurerutsa maitiro ekugadzirira samples yekuongorora.

Kuenderana: Iyi machubhu yakagadzirirwa kushandiswa nemhando yakatarwa kana mavara emavara, anoverengera zvakaringana.

Nzvimbo Yakasimbiswa: Gadzira rakasungwa rinodzivirira kusvibiswa uye kubuda kwemvura, kuchengetedza kutendeka kwemuenzaniso panguva yekuedzwa.

Kugadzirira kweCOD kuedzwa

Usati watanga iyo cod kuyedza maitiro, iwe unofanirwa kuve wakagadzirirwa zvizere. Heano matanho ekutevera:

1. Unganidza zvishandiso zvinodiwa

Ita shuwa kuti iwe une zvese zvinodiwa nemidziyo uye zvigadzirwa, kusanganisira:

Cod test tubesine dzimba dzisina kuyerwa
Muenzaniso wemvura kuti uongororwe
Photometer kana colorimeter inoenderana neCOD bvunzo tubes
Pipette kana syringe yekuunganidza samples
Zvivakwa zvekudzivirira pachako (ppe) senge magurovhosi uye goggles

2. Muenzaniso wekuunganidza

Unganidza iyo yemvura sampuli kuti uongororwe yeCOD. Izvo zvakakosha kutevedzera maitiro akakodzera ekuratidzira kuti uve nechokwadi chekuti muenzaniso uri mumiriri weSurware mvura. Heano mamwe matanho ekuunganidza ekuunganidza:

Shandisa midziyo yakachena: Ita shuwa kuti mudziyo unoshandiswa kuunganidza sampu yakachena uye isina kusvibiswa.

Dzivisa kusvibiswa: Chenjera kuti udzivise chero nyaya yekune dzimwe nyika mumuenzaniso panguva yekuunganidza maitiro.

Ongorora pakarepo: ita cod ongorora nekukurumidza sezvinobvira mushure mekuunganidzwa kwemuenzaniso. Kana kuongororwa hakugoneki pakarepo, chengetedza muenzaniso munzvimbo inotonhorera yekudzora shanduko.

3. SAMPLE KUSVIRA (kana zvichidikanwa)

Kana iwe usingakwanise kuongorora yako sampula pakarepo, ungangoda kuuchengetedza. Kune cod samples, inowanzo kukurudzirwa kudzikisa iyo PH kusvika ku2 kana kushoma nekuwedzera yakadzika Sulfutic acid (h₂so₄). Izvi zvichabatsira kusimbisa muenzaniso uye kuderedza zviito zvezvinhu kusvikira kuongororwa kunogona kuitwa. Gara uchitevera nhungamiro dzekuchengetedza kana uchibata acids.

Kuita bvunzo coD

Paunenge uchinge wagadzirira yako sampux uye yakaunganidza michina inodiwa, unogona kuita bvunzo yeCOD. Heino nhanho-ne-nhanho gwara:

1. Gadzirira COD Test Tubes

Label the machubhu: zvakajeka chinyorwa chega chega chebhuruu neiyo sampuli id kuti udzivise mukana uyu.

Wedzera sample: uchishandisa pipette kana syringe, nyatsowedzera sampuli yemvura kune iyo cod test tube. Tevedza mirayiridzo yemugadziri yehuwandu hwemuenzaniso kuti uwedzere.

2. Wedzera Reagents

Pre-yakayerwa Reagents:Cod test tubeshuya neyekuyerwa marefu. Ita shuwa kuti adzorasve dzakakwana uye machubhu akaiswa chisimbiso usati waenderera.

Sakanidza mushe

3. Kupisa iyo bvunzo tube

Inopisa nhanho: Isa iyo test tube muchivhara kana yekugezera yemvura uye kupisa iyo pane yakatsemuka tembiricha (kazhinji inotenderedza 150 ° C) yenguva yakakurudzirwa (kazhinji maawa anokurudzirwa (kazhinji maawa maviri). Iyi nhanho ndeyekutsoropodza kweiyo oxidation maitiro kuti zviitike.

Kuchengetedza Kwekuchengetedza: Shandisa Chenjedzo Kana uchibata michina inopisa uye ona kuti bvunzo tube yakaiswa zvakachengeteka kuti udzivise kupururudza.

4. Kutonhora iyo bvunzo tube

Mushure mekunge nguva yekudziya yazara, bvisa iyo test tube kubva kune inopisa sosi uye ubvumire kuti itonhore kutonhora mukamuri tembiricha. Iyi nhanho yakakosha kudzivirira kukuvadza kune iyo Photometer kana colorimeter panguva yekuongorora.

5. Kuyera Cod

Ongorora ongororo: Kamwe bvunzo yeTebhu yakadzora, inoiisa mumota kana colorimeter. Calibrate chiridzwa zvichienderana nemirairo yemugadziri uye kuyera iyo yekubata.

Kurekodha mhinduro: Chiridzwa chinopa kuverenga kunoenderana neye cod coldration mune sampuli. Nyora zvakaringana mhedzisiro yekuwedzera kuongororwa.

Iwe unoziva here kuti basa rekushanda reCOD vial? Ndokumbirawo kuti muverenge chinyorwa ichi:Iyo inoshanda nheyo ye cod vial

Mhedziso

Kushandiswa kwakakodzera kweCod test tubesKuti uwane mvura yemvura kuyedzwa ndeyekutsoropodza kuwana mhedzisiro yakarurama uye yakavimbika. Nekutevera nhanho dzakatsanangurwa mune ino blog, kusanganisira kugadzirira kwemigwagwa, maitiro ekuedzwa, uye maitiro akanakisa, iwe unogona kuve nechokwadi chekuongorora kweCOD. Iyi nzira inogona kupa zvakakosha ruzivo mumatanho ekusvibiswa organic mumvura, kubatsira kuchengetedza hutano hwevanhu uye nharaunda. Kunzwisisa maitiro ekushandisa zvinobudirira cod test tubes kunogona kubatsira zvirinani kubata uye kutarisa kwemvura mhando, kungave mubharatori kana mumunda wemunda.
