I-Shanghai Chun Ye "izinikele kwiingenelo zokusingqongileyo kwindalo kwiingenelo zoqoqosho kwindalo" zenjongo yenkonzo.Ububanzi beshishini bugxile kakhulu kwisixhobo sokulawula inkqubo yemizi-mveliso, isixhobo sokujonga ngokuzenzekelayo somgangatho wamanzi kwi-intanethi, inkqubo yokujonga kwi-intanethi ye-VOCs (iikhompawundi zendalo eziguquguqukayo) kunye nenkqubo ye-alamu yokujonga kwi-intanethi ye-TVOC, ukufunyanwa kwedatha ye-Intanethi yezinto, isiphelo sokuhambisa nokulawula, inkqubo yokujonga ngokuqhubekayo umsi we-CEMS, isixhobo sokujonga ingxolo yothuli kwi-intanethi, ukujonga umoya kunye nezinye iimveliso zophando nophuhliso, imveliso, intengiso kunye nenkonzo.
Isishwankathelo seMveliso
Ithiyori ephambilipHumlinganiselo we-electrode nguI-equation yeNernst. Iisensa ezisetyenziswa kuhlalutyo lwe-potentiometric zibizwa ngokuba ziiseli ze-galvanic. Iseli ye-galvanic yinkqubo eguqula amandla e-chemical reaction abe ngamandla ombane. I-voltage yale seli ibizwa ngokuba yi-electromotive force (EMF). Le electromotive force (EMF) ineeseli ezimbini ezinesiqingatha. Iseli enye enesiqingatha ibizwa ngokuba ziisensa zokulinganisa, kwaye amandla azo anxulumene nomsebenzi othile we-ion; Elinye isiqingatha seseli yiseli yesiqingatha sesalathiso, edla ngokubizwa ngokuba yisensa yesalathiso, edla ngokudityaniswa nesisombululo sokulinganisa kwaye iqhagamshelwe kwiisixhobo sokulinganisa.
I-ORP(i-REDOX potential) luphawu olubalulekileyo lomgangatho wamanzi. Nangona ingenakubonakalisa ngokuzimeleyo umgangatho womgangatho wamanzi, inokudibanisa ezinye izalathisi zomgangatho wamanzi ukuze ibonise imeko-bume yendalo kwinkqubo ye-aquarium.
Emanzini, into nganye ineyayoIipropati zeREDOXNgamazwi alula, sinokuqonda ukuba: kwinqanaba elincinci, into nganye eyahlukileyo inomthamo othile wokunciphisa i-oxidation, kwaye ezi zinto zineempawu ezahlukeneyo zokunciphisa i-oxidation zinokuchaphazela enye kwenye, kwaye ekugqibeleni zenze ipropati ethile yokunciphisa i-oxidation ye-macroscopic. I-REDOX potential isetyenziselwa ukubonisa iimpawu zokunciphisa i-oxidation ye-macroscopic yazo zonke izinto kwi-aisisombululo samanziOkukhona amandla e-REDOX ephezulu,kokukhona i-oxidation iqina ngakumbi, okukhona amandla esezantsi, kokukhona i-oxidation ibuthathaka. Amandla e-positive abonisa ukuba isisombululo sibonisa i-oxidation ethile, kwaye amandla angenamandla abonisa ukuba isisombululoibonisa ukuncitshiswa.
Uqhagamshelo lwe-electrode
Ukuze uqhagamshele i-electrode ye-pH/ORP kwisixhobo, i-electrode enobushushu nayo kufuneka iqhagamshele i-terminal yobushushu kwisixhobo, kwaye ikhethe inkqubo yokuhlawula ubushushu ehambelanayo kwisixhobo.
Umzobo woFakelo
① Ufakelo lodonga olusecaleni: qinisekisa ukuba i-engile yojongano ingaphezulungaphezu kwama-degrees ayi-15;
② Ufakelo lweflange ephezulu:nikela ingqalelo kubungakanani beflengikunye nobunzulu bokufakwa kwe-electrode;
③ Ukufakelwa kwepayipi:nika ingqalelo kububanzi bombhobho, izinga lokuhamba kwamanzi kunye noxinzelelo lwemibhobho;
④Ufakelo lomlambo: nika ingqalelo kwisantya sokuhamba kwamanzi kunye noxinzelelo lokuhamba kwamanzi;
⑤ Ufakelo olutshisiweyo:qaphela ubude benkxaso.
Ukugcinwa kunye nokugcinwa kwe-electrode
Xa usebenzisa i-electrode, isigqubuthelo sokukhusela i-electrode kufuneka siqale sikhutshwe, kwayeIbhalbhu ye-electrode kunye ne-liquid junction kufuneka zifakwe kulwelo olulinganisiweyo.
Ukuba kufunyaniswe ukubaiikristale zetyuwaZenziwe entlokweni ye-electrode nakwisigqubuthelo sokukhusela ngenxa yokuphuma komphunga kwe-electrolyte ngaphakathi kwe-electrode ngefilimu ye-dialysis, ayichaphazeli ukusetyenziswa okuqhelekileyo kwe-electrode, nto leyo ebonisa ukuba ifilimu ye-electrode dialysis iqhelekile, kwaye inokubaihlanjwe ngamanzi.
Qaphela ukuba ngabakukho amaqamza kwibhalbhu yeglasi, ungabamba isiphelo esingaphezulu se-electrode uze ushukumise amaxesha ambalwa.
Ukuqinisekisa ukuba ixesha lokuphendula likhawuleza, ifilimu yesenzi seglasi ye-electrode kufuneka ihlale imanzi, kwaye emva kokulinganisa okanye ukulinganisa, i-electrode kufuneka icocwe ngokuchanekileyo kwaye inani elithile lolwelo lokukhusela i-electrode kufuneka lifakwe kwisigqubuthelo sokukhusela i-electrode. Isisombululo sokugcina yayiyi-3mol/L potassium chloride solution.
Jonga ukuba isiphelo se-electrode somile na. Ukuba kukho ibala, lisule ngeutywala obungenamanzi uze womise nge-air ngaphambi kokuba uyisebenzise.
Ukuntywiliselwa ixesha elide emanzini acocekileyo okanye kwizisombululo zeproteni kufuneka kuthintelwe, kwayeUkudibana negrisi ye-silicone kufanele kuthintelwe.
Ukuba i-electrode isetyenziswa ixesha elide, ifilimu yayo yeglasi inokuba lukhazimla okanye ibe neediphozithi, ezinokuthihlanjwa nge-10% ye-hydrochloric acid exutywe ne-10% uze uhlanjwe ngamanziKucetyiswa ukuba umsebenzisi ayicoce rhoqo i-electrode aze ayilinganise ngesixhobo.
Ukuba i-electrode ayinakulungiswa kwaye ilinganiswe ngokwesiqhelo emva kokugcinwa nokugcinwa kwe-electrode kusetyenziswa ezi ndlela zingasentla, i-electrode ayinakufumana impendulo yayo, nceda uyitshintshe i-electrode.
