Shanghai Chun Ye "cog lus rau qhov zoo ntawm ib puag ncig mus rau hauv qhov zoo ntawm kev lag luam ecological" ntawm lub hom phiaj kev pabcuam.Lub hom phiaj ua lag luam feem ntau yog tsom mus rau cov cuab yeej tswj kev lag luam, cov cuab yeej saib xyuas dej zoo online, VOCs (cov khoom sib xyaw ua ke) online saib xyuas system thiab TVOC online saib xyuas lub tswb ceeb toom system, Internet of Things cov ntaub ntawv tau txais, kis thiab tswj chaw nres nkoj, CEMS pa luam yeeb tas mus li saib xyuas system, plua plav suab nrov online saib xyuas cuab yeej, saib xyuas huab cua thiab lwm yam khoom R & D, ntau lawm, muag khoom thiab kev pabcuam.
Txheej Txheem Cej Luam Khoom
Lub hauv paus ntsiab lus ntawmpHkev ntsuas electrode yogNernst equationCov sensors siv hauv kev tshuaj xyuas potentiometric hu ua galvanic cells. Lub galvanic cell yog ib lub kaw lus uas hloov lub zog ntawm cov tshuaj lom neeg mus rau hauv lub zog hluav taws xob. Lub zog ntawm lub cell no hu ua electromotive force (EMF). Lub zog electromotive (EMF) no muaj ob lub cell thiab ib nrab. Ib lub cell thiab ib nrab hu ua measuring sensors, thiab lawv lub peev xwm muaj feem cuam tshuam nrog kev ua haujlwm ion tshwj xeeb; Lub cell ib nrab yog lub cell ib nrab siv, feem ntau hu ua reference sensor, uas feem ntau sib txuas lus nrog cov tshuaj ntsuas thiab txuas nrogntsuas ntsuas.
ORP(REDOX muaj peev xwm) yog ib qho tseem ceeb hauv cov dej zoo. Txawm hais tias nws tsis tuaj yeem cuam tshuam qhov zoo ntawm cov dej zoo, nws tuaj yeem koom ua ke lwm cov ntsuas dej zoo los cuam tshuam qhov chaw ib puag ncig hauv lub thoob dej yug ntses.
Hauv dej, txhua yam khoom muaj nws tus kheejCov khoom REDOXHauv cov lus yooj yim, peb tuaj yeem nkag siab tias: ntawm qib micro, txhua yam khoom sib txawv muaj qee qhov peev xwm oxidation-reduction, thiab cov khoom no nrog cov khoom sib txawv oxidation-reduction tuaj yeem cuam tshuam rau ib leeg, thiab thaum kawg tsim cov khoom macroscopic oxidation-reduction. Lub peev xwm hu ua REDOX yog siv los qhia txog cov khoom macroscopic oxidation-reduction ntawm txhua yam khoom hauv ib qhocov kua dejQhov siab dua ntawm REDOX peev xwm,qhov muaj zog dua qhov oxidation, qhov qis dua qhov muaj peev xwm, qhov oxidation tsis muaj zog. Qhov muaj peev xwm zoo qhia tau tias cov tshuaj qhia qee qhov oxidation, thiab qhov muaj peev xwm tsis zoo qhia tau tias cov tshuajqhia txog kev txo qis.
Kev sib txuas ntawm electrode
Yuav kom txuas lub pH/ORP electrode rau lub cuab yeej, lub electrode uas muaj qhov kub thiab txias kuj yuav tsum txuas lub qhov kub thiab txias rau lub cuab yeej, thiab xaiv qhov kev pab cuam them nyiaj kub sib phim ntawm lub cuab yeej.
Daim duab teeb tsa
① Kev teeb tsa phab ntsa sab: xyuas kom meej tias lub kaum sab xis ntawm lub interface loj duakub tshaj 15 degrees;
② Kev teeb tsa flange sab saum toj:them sai sai rau qhov loj ntawm flangethiab qhov tob ntawm qhov ntxig electrode;
③ Kev teeb tsa kav dej:them sai sai rau lub cheeb ntawm cov kav dej, tus nqi dej ntws thiab lub zog ntawm cov kav dej;
④Kev teeb tsa ntws: xyuam xim rau qhov ntws thiab qhov siab ntws;
⑤ Kev teeb tsa hauv qab dej:ua tib zoo saib qhov ntev ntawm kev txhawb nqa.
Kev saib xyuas thiab txij nkawm ntawm electrode
Thaum siv lub electrode, lub hau tiv thaiv electrode yuav tsum tau unscrewed ua ntej, thiablub teeb electrode thiab qhov sib txuas ua kua yuav tsum tau muab tso rau hauv cov kua ntsuas.
Yog pom tias muaj li ntawdcov ntsev siv lead uaraug tsim nyob rau hauv lub taub hau electrode thiab lub hau tiv thaiv vim yog qhov evaporation ntawm electrolyte sab hauv electrode los ntawm dialysis zaj duab xis, nws tsis cuam tshuam rau kev siv electrode ib txwm muaj, qhia tias electrode dialysis zaj duab xis yog qhov ib txwm muaj, thiab tuaj yeem ua tauntxuav nrog dej.
Saib seb puas yogmuaj cov npuas dej hauv lub teeb iav, koj tuaj yeem tuav qhov kawg sab saud ntawm lub electrode thiab co ob peb zaug.
Yuav kom paub tseeb tias lub sijhawm teb sai, daim zaj duab xis iav sensor electrode yuav tsum tau khaws cia kom ntub, thiab tom qab ntsuas lossis calibration, lub electrode yuav tsum tau ntxuav kom huv si thiab ib qho kua tiv thaiv electrode yuav tsum tau nchuav rau hauv lub hau tiv thaiv electrode. Cov kua khaws cia yog 3mol / L potassium chloride kua.
Xyuas seb lub qhov kawg ntawm lub electrode puas qhuav. Yog tias muaj tej yam tsis huv, so nws nrogcawv anhydrous thiab tshuab kom qhuav ua ntej siv.
Yuav tsum tsis txhob muab tso rau hauv dej distilled lossis cov kua protein ntev ntev, thiabyuav tsum tiv thaiv kev sib cuag nrog cov roj silicone.
Yog tias lub electrode siv ntev, nws cov iav zaj duab xis yuav ua rau pom tseeb lossis muaj cov av tso, uas tuaj yeemntxuav nrog 10% dilute hydrochloric acid thiab ntxuav nrog dej. Nws raug pom zoo kom tus neeg siv ntxuav lub electrode tas li thiab calibrate nws nrog lub cuab yeej.
Yog tias lub electrode tsis tuaj yeem kho thiab ntsuas tau ib txwm tom qab kev saib xyuas thiab kev saib xyuas ntawm lub electrode siv cov txheej txheem saum toj no, lub electrode tsis tuaj yeem rov qab tau nws cov lus teb, thov hloov lub electrode.
