Isikhokelo esipheleleyo: Isebenza njani i-Peoporographic?

Kwintsimi yokuhlolwa kweliso kwindalo esingqongileyo kunye novavanyo lwamanzi lwamanzi, ukuchithwa kweoksijini (ngaba) imilinganiselo yeoksijini idlala indima ebalulekileyo. Enye yezona teknoloji ezisetyenziswa ngokubanzi zenza ukuba i-polarographic yenziwa.

Esi sikhokelo sibanzi, siya kuqhuba kwimithetho-siseko yokusebenza ye-polarographic do probe, izinto zayo, kunye nezinto ezichaphazela ukuchaneka kwayo. Ekupheleni kweli nqaku, uya kuba nokuqonda okuqinileyo kwendlela esisebenza ngayo esi sixhobo sibalulekileyo.

Ukuqonda ukubaluleka kokulinganisa ioksijini:

Indima yeoksijini echithwe kwi-Oxegen kumgangatho wamanzi:

Ngaphambi kokuba siqhubeke ekusebenzeni kwe-polarographic do probe Pebe, masiqonde isizathu sokuba ioksijini yiparamitha ebalulekileyo yokuvavanya umgangatho wamanzi. Yenza amanqanaba achaphazela ngokuthe ngqo ubomi base-sumatic, njengoko bemisela inani leoksijini ekhoyo yeentlanzi kunye nezinye izinto ezikwimibutho yamanzi. Ukubeka iliso kwenza kubaluleke kakhulu ekugcineni impilo yendalo kunye nokuxhasa iinkqubo ezahlukeneyo zebhayoloji.

Isishwankathelo se-polarographic do probe:

Yintoni i-polarographic do probe?

I-polarographic do probe yinzwa ye-elektroniki ye-elektroniki eyilelwe ukunyibilikisa ioksijini kwiindawo ezahlukeneyo ze-Aquatic. Ixhomekeke kumgaqo wokuncitshiswa kweoksijini kumhlaba omatshini, owenza ukuba yeyeyona ndlela ichanekileyo nezisetyenzisiweyo zendlela yokwenza oko.

Izinto ze-polarographic do probe:

I-polarographic ye-Probe inamacandelo aphambili:

a) I-Cathode: I-Cathode yeyona nto iphambili yenzeka apho kuncitshiswa ioksijini.

b) Anode: I-anode igqibezela iseli ye-electrochemical, ivumela ukuncitshiswa kweoksijini kwi-Mahode.

c) Isisombululo se-electrolyte: Iprobe inesisombululo se-electrolyte eququzelela impendulo ye-elektroniki.

d) I-membrane: I-membrane yegesi yegesi igubungela izinto ezivaliweyo, ukuthintela ukunxibelelana ngqo namanzi ngelixa uvumela ioksijini.

Imigaqo esebenzayo ye-polarographic do probe:

•  Impendulo yokunciphisa ioksijini:

Isitshixo se-polarographic do Umsebenzi we-probe ubuxoki kwi-OXYHENT YOKUGQIBELA. Xa iprojeki ingene emanzini, ioksijini evela kwindawo engqongileyo yahluka ngokusebenzisa i-membrane yegesi kwaye inxibelelana ne-cahode.

• Inkqubo yeseli ye-electroniki:

Ekunxibelelaneni ne-Mahode, iimolekyuli zeoksijini zithathe inxaxheba ekuphenduleni, apho bafumana ii-elektroni. Olu ncedo lokunciphisa luququzelelwa bubukho besisombululo se-electrolyte, esisebenza njengendawo yokudluliselwa kwe-elektroni phakathi kwe-Makhaya kunye ne-ATODE.

•  Isizukulwana sangoku kunye nomlinganiselo:

I-Electroniptriction ivelisa ngokulinganayo ngokuhambelana neoksijini echithwe emanzini. I-Probe's Elektroniki ilinganisa le yangoku, kwaye emva kokungacingeli ngokufanelekileyo, iguqulwa ibe yichiza leoksijini yeoksijini (umzekelo, mg / l okanye i-PPM).

Izinto ezichaphazela i-polarographic zenza ukuchaneka kwe-probe:

a.Iqondo lokushisa:

Iqondo lokushisa liyiphembelela ukuchaneka kwe-polarographic do probe. Uninzi lwenzeka lufikelwe kwimbuyekezo yobushushu eyakhiwe, eqinisekisa imilinganiselo echanekileyo nakwiimeko ezahlukeneyo zobushushu.

b.Ityuwa kunye noxinzelelo:

Ityuwa kunye noxinzelelo lwamanzi lunokuchaphazela ukufundwa kwenkqubo. Ngethamsanqa, i-protsies yanamhlanje ixhotyiswe ngeempawu zokuhlawula ezi zinto, ziqinisekisa imilinganiselo ethembekileyo kwiindawo ezahlukeneyo.

c.Ukulungelelanisa kunye nokugcinwa:

Ukulinganisa rhoqo kunye nokulungiswa ngokufanelekileyo kwe-polarographic do probe kubaluleke kakhulu ukufumana ukufundwa ngokuchanekileyo. Ukulinganisa kufuneka kwenziwe ngezisombululo zokulinganisa ezisemgangathweni, kwaye izinto zeProbe kufuneka zicocwe kwaye zitshintshwe njengoko kufuneka.

I-Boquetritha yedijithali ye-Poularographita ye-Probe-Ukuqhubela phambili ukubekwa kweliso kumanzi

I-Boquameding ibonelela ngezisombululo zomphetho ezinqumlayo kwindalo yokubekwa kweliso kumanzi. Enye yeemveliso zabo zokuzimaI-Digital Polarographic do probe, i-IOI ye-IOIP ephezulu enikwe amandla e-electrode eyenzelwe ukubonelela ngomgangatho weoksijini echanekileyo nethemba.

Emva koko, siya kuphonononga izibonelelo ezibalulekileyo zeli nkalo yokufumana intsha kwaye siqonde ukuba kutheni imele ukuba inyulu phezulu kumashishini ahlukeneyo.

IINGXAKI ZOKUGQIBELA I-POREAROMIT

A.Uzinzo lwexesha elide kunye nokuthembeka:
