Kuyeserera kwamankhwala kwa oxygen (cod) kuyezetsa ndi njira yofunika kwambiri yowunikira mtundu wamadzi kuchokera ku madzi osiyanasiyana, kuphatikiza mitsinje, nyanja, ndi zomera zonyowa madzi. COD imayeza kuchuluka kwa mpweya wofunikira kuti mugwiritse ntchito mankhwala osokoneza bongo ambiri m'madzi, omwe angasonyeze kuchuluka kwa kuipitsidwa komwe kumapezeka. Kugwiritsa ntchito bwino machubu a cod ndikofunikira kuti mupeze zotsatira zabwino komanso zodalirika. Blog iyi ikuthandizani pakugwiritsa ntchito machubu a cod kuti muyese madzi abwino, kuphatikiza kukonzekera, njira, komanso machitidwe abwino.

CATT CATTamapangika makalasi kapena machubu oyeserera a pulasitiki omwe amakhala ndi ma reagents oyeserera a cod. Machubu awa amagwiritsidwa ntchito ndi makina a Phondometric kuti adziwe kuchuluka kwa cod m'matumba ammadzi. Kuyesaku kumakhazikitsidwa chifukwa chochita chiwopsezo cha organic chogwira ntchito, nthawi zambiri potaziyamu dichromate, mu yankho la acid.

Kodi mukudziwa kugwiritsa ntchito machubu a cod mumadzi akuwunika? Chonde werengani nkhaniyi: Momwe COBE YOPHUNZIRA IZI IMAPHUNZITSIDWA MU TOP

Mawonekedwe a COD kuyesa machubu

Zoyeserera Zoyeserera: Machubu a cod amabwera ndi ma reagent otayika kale, osavuta kusintha njira yokonzekera zitsanzo zowunikira.

Kugwirizana: Machubu awa amapangidwa kuti azigwiritsidwa ntchito ndi zithunzi zapadera kapena zokongoletsa, ndikuwonetsetsa zomveka.

Malo osindikizidwa: Mapangidwe osindikizidwa amalepheretsa kuipitsidwa ndi kusinthanitsa, kusunga umphumphu wa tempuya.

Kukonzekera kuyesa kwa cod

Musanayambe kusankha kwa cod, muyenera kukonzekera bwino. Nayi njira zotsatirira:

1. Sonkhanitsani zida zofunika

Onetsetsani kuti muli ndi zida zonse zofunikira, kuphatikiza:

CATT CATTndi zoyeserera zoyeserera
Madzi A Samp kuti ayesedwe
Photometer kapena mtundu wogwirizana ndi machubu a cod
Pipette kapena syringe kuti musonkhanitse zitsanzo
Zida zoteteza zaumwini (PPE) monga magolovesi ndi magalasi

2.

Sungani zitsanzo zamadzi kuti zisanthulidwe ndi cod. Ndikofunikira kutsatira njira zoyenerera zolondola kuti muwonetsetse kuti sampuliyo ndi yoimira kasupe wamadzi. Nayi malangizo otolera:

Gwiritsani ntchito zoyera: Onetsetsani kuti chidebe chomwe chimagwiritsidwa ntchito kutolera zitsanzozo ndi zoyera komanso zopanda vuto.

Pewani Kuipitsidwa: Samalani kuti mukonzenso zakunja zilizonse mu zitsanzo pa njira yosungiramo.

Pendani nthawi yomweyo: gwiranani ndi Cod posachedwa pambuyo pazokambirana. Ngati kusanthula sikutheka nthawi yomweyo, sungani zitsanzo pamalo abwino kuti muchepetse kusintha kwa mapangidwe.

3.. Kusunga zitsanzo (ngati kuli kofunikira)

Ngati mukulephera kusanthula zitsanzo zanu nthawi yomweyo, mungafunike kuyisunga. Kwa zitsanzo za COD, nthawi zambiri zimalimbikitsidwa kutsitsa PH mpaka 2 kapena zochepa powonjezera sulufuric acid (H₂so₄). Izi zikuthandizira kukhazikitsa zitsanzo ndikuchepetsa ntchito yachilengedwe mpaka kuyesa kumatha kuchitidwa. Nthawi zonse tsatirani malangizo otetezedwa akamagwira ma acid.

Kuchita mayeso a cod

Mukakonza zitsanzo zanu ndikusonkhanitsa zida zofunika, mutha kuyesa mayeso a cod. Nayi yotsogolera pa sitepe ndi sitepe:

1. Konzani machubu a cod

Lambulani machubu: lembani bwino chubu chilichonse ndi ID ya zitsanzo kuti mupewe chisokonezo pambuyo pake.

Onjezani sampu: Kugwiritsa ntchito pipette kapena syringe, onjezerani madzi mosamala ku chubu cha cod. Tsatirani malangizo a wopanga kuti mupeze zitsanzo za zitsanzo kuwonjezera.

2. Onjezani ma reagents

Zoyeserera Zoyeserera:CATT CATTbwerani ndi zoyeserera zoyesedwa. Onetsetsani kuti ma reagents ali osavomerezeka ndipo machubu amasindikizidwa musanachitike.

Sakanizani bwino: Mukatha kuwonjezera zitsanzo, cap chubu mwamphamvu ndikusakaniza bwino kuti zitsimikizidwe kwathunthu ndikuchita ndi chitsanzo.

3. Kutenthetsa chubu

Kutenthetsa Gawo: Ikani chubu choyesera mu block kapena kusamba kwamadzi ndikutenthetsa pamoto wotchulidwa (nthawi zambiri pafupifupi 150 ° C) kwa nthawi yovomerezeka (nthawi zambiri maola 2). Izi ndizofunikira kwambiri kuti maxidation achitike.

Kusamala: Gwiritsani ntchito mosamala mukamagwiritsa ntchito zida zotentha ndikuonetsetsa kuti chubu choyeserera siyikidwa bwino kuti isapewe masikono.

4. Kuzizira chubu choyesera

Pambuyo pa nthawi yotentha ikwanira, chotsani chubu choyeseracho kuchokera pa gwero la kutentha ndikulola kuti lizizire kutentha. Gawo ili ndilofunika kuti muchepetse kuwonongeka kwa chithunzi kapena mtundu wophatikizira.

5.

Kusanthula kwa Photometric: Kamodzi chubu choyeserera chazirala, ikani pamoto kapena mawonekedwe. A Carnibiza chida malinga ndi malangizo a wopanga ndikuyesa kuyamwa.

Kulemba Zotsatira zake: Chidacho chidzapereka kuwerenga komwe kumagwirizana ndi cod ndendeyo. Lembani molondola zotsatira zakusanthula zina.

Kugwiritsa ntchito bwinoCATT CATTKuyesa kwamadzi ndikofunikira kupeza zotsatira zolondola komanso zodalirika. Potsatira masitepe omwe afotokozedwa mu blog, kuphatikizapo kukonzekera kwake, njira zoyesera, komanso machitidwe abwino, mutha kuwonetsetsa kuti santhula wovomerezeka. Njirayi imatha kumvetsetsa zofunikira m'magawo a zounitsidwa ndi madzi, zimathandizira kuteteza thanzi la anthu komanso chilengedwe. Kuzindikira momwe mungagwiritsire ntchito bwino machubu a COD kungathandize kuwongolera bwino ndikuwunika madzi, kaya mu labotale kapena m'munda.
