Imitha yokugxilisa i-ion iyithuluzi elivamile lokuhlaziya i-electrochemical elabhorethri elisetshenziselwa ukukala ukugxila kwe-ion esixazululweni.Ama-electrode afakwa esixazululweni ukuze akalwe ndawonye ukuze akhe uhlelo lwe-electrochemical lokulinganisa.
Imitha ye-ion, eyaziwa nangokuthi imitha yomsebenzi we-ion, umsebenzi we-ion ubhekisela ekuhlanganiseni okuphumelelayo kwama-ion abamba iqhaza ekuphenduleni kwe-electrochemical kusixazululo se-electrolyte.Umsebenzi wemitha yokugxilisa i-ion: uhlobo lokuthinta lwesikrini esikhulu se-LCD isibonisi, isixhumi esibonakalayo sokusebenza sesiNgisi esigcwele.Ngokulinganiswa kwamaphuzu amaningi (kufika kumaphuzu angu-5) kuvumela abasebenzisi ukuthi benze isethi yabo evamile yemisebenzi.
I-ion analyzer ingathola kalula futhi ngokushesha ngobuningiI-fluoride ions, i-nitrate radicals, i-pH, ubulukhuni bamanzi (Ca 2 + , Mg 2 + ions), F-, Cl-, NO3-, NH4+, K+, Na+ ionsemanzini, kanye nokugxila okunembile kwezinto ezingcolile ezihlukahlukene.
Ukuhlaziywa kwe-ion kubhekisela ekukhetheni izindlela zokuhlaziya ezihlukene zokuhlaziya nokuhlolwa ngokuya ngezici ezihlukene zesampula ukuze kutholwe uhlobo nokuqukethwe kwezinto noma ama-ion kusampula, ukuze kubonwe ukuhlaziywa kohlobo nokuqukethwe kwezinto noma ama-ion kusampula, kanye nokuhlangabezana nezidingo zamakhasimende zokuhlaziywa kwe-ion element.
WorkingPi-rinciple
I-ion analyzer isebenzisa kakhulu indlela yokulinganisa i-ion ekhethiwe ukuze kutholakale ukutholakala okunembile.Ama-Electrode ensimbi: i-fluorine, i-chlorine, i-sodium, i-nitrate, i-ammonia, i-potassium, i-calcium, nama-electrode ereferensi.I-electrode ngayinye inolwelwesi olukhethayo lwe-ion, olusabela nama-ion ahambisanayo kusampula ezohlolwa.Ulwelwesi luwukushintshanisa i-ion, futhi amandla phakathi koketshezi, isampula kanye nolwelwesi lungatholwa ngokusabela ngenkokhelo ye-ion ukuze kushintshwe amandla olwelwesi..Umehluko phakathi kwamandla amabili atholwe nhlangothi zombili zolwelwesi uzokhiqiza i-current.Isampula, i-electrode eyireferensi, kanye noketshezi lwe-electrode eyireferensi lwakha uhlangothi olulodwa lwe-"loop", futhi ulwelwesi, uketshezi lwe-electrode yangaphakathi, kanye ne-electrode yangaphakathi yakha ngakolunye uhlangothi.
Umehluko ekugxilweni kwe-ionic phakathi kwesisombululo se-electrode yangaphakathi kanye nesampula ikhiqiza amandla kagesi e-electrochemical kuwo wonke ulwelwesi lwe-electrode esebenzayo, eholela ku-amplifier nge-electrode yangaphakathi esebenza kakhulu, kanye ne-electrode eyireferensi nayo iholelwa endaweni ye-electrode esebenzayo. i-amplifier.Ijika lokulinganisa litholwa ngokulinganisa isisombululo esinembile esijwayelekile sokugxiliswa kwe-ion okwaziwayo ukuze kutholwe ukugxiliswa kwe-ion kusampula.
Ukufuduka kwe-ion kwenzeka ngaphakathi kongqimba olunamanzi lwe-matrix ye-electrode ekhethiwe ye-ion lapho ama-ion alinganisiwe esixazululo ethintana nama-electrode.Ushintsho ekushajweni kwama-ion afudukayo lunamandla, okushintsha amandla phakathi kwezindawo zolwelwesi, okudala umehluko ongaba khona phakathi kwe-electrode yokulinganisa kanye ne-electrode eyireferensi.
Aisicelo
Gada izilinganiso ze-ammonia, i-nitrate, njll. emanzini angaphezulu, emanzini angaphansi komhlaba, izinqubo zezimboni, kanye nokuhlanza indle.
Iimitha yokuhlushwa ye-fluoride ionyakhelwe ukukala iokuqukethwe kwe-fluoride ionkwisisombululo esinamanzi, ikakhulukazi ukuqapha ikhwalithi yamanzi ahlanzekile kakhulu ezitshalweni zikagesi (njengesitimu, i-condensate, amanzi okuphakelayo okubhayela, njll.) Amakhemikhali, ama-microelectronics neminye iminyango, inquma ukugxila (noma umsebenzi)i-fluoride ionsemanzini emvelo, amanzi ezimbonini nakwamanye amanzi.
Mukulungiswa
1. Ungaxazulula kanjani uma umtshina wehluleka
Kunezizathu ezi-4 zokuthi kungani umtshina wehluleka:
①Ipulaki yomtshina ikhululekile ngesihlalo sebhodi lomama;
②Umtshina ngokwawo uphukile;
③ Isikulufu sokulungisa kumongo wevalvu kanye ne-motor shaft ejikelezayo ayiboshelwa endaweni;
④ I-spool ngokwayo iqine kakhulu ukuthi ingaphenduka.I-oda lokuhlola lithi ③-①-④-②.
2. Izizathu nezindlela zokwelapha zokumunca isampula eliphansi
Kunezizathu ezine eziyinhloko zesifiso esibi sesampula, esihlolwa ngendlela "elula ukuya kokuyinkimbinkimbi":
①Hlola ukuthi ingabe amapayipi axhumayo okuxhumana ngakunye kwepayipi (okuhlanganisa namapayipi axhumayo phakathi kwama-electrode, phakathi kwama-electrode namavalvu, naphakathi kwama-electrode namapayipi ephampu) ayavuza.Lesi simo sibonakaliswa njengokuthi alikho isampula lokumunca;
② Hlola ukuthi ishubhu lepompo libambekile yini noma likhathele kakhulu, futhi ishubhu lepompo elisha kufanele lishintshwe ngalesi sikhathi.Isimanga ukuthi ishubhu lepompo lenza umsindo ongajwayelekile;
③ Kukhona ukuna kwamaprotheni epayipini, ikakhulukazi emajoyintini.Lesi simo sibonakala njengokuma okungazinzile kwenqubo yesivinini sokugeleza koketshezi, ngisho noma ishubhu yepompo ithathelwa indawo entsha.Isixazululo ukususa amalunga bese uwahlanza ngamanzi;
④ Kunenkinga ngevalvu ngokwayo, ngakho yihlole ngokucophelela
