Daim ntawv thov ntawm PHO MOOT hauv kev ntsuas tus nqi ntawm cov av
Cov xov tooj hluav taws xob anidity yog cov cuab yeej siv thiab cov cuab yeej siv tau ntau, feem ntau yog siv los ntsuas qhov ntsuas ntawm PHIC. Nws tseem tuaj yeem ntsuas ION electrode tej peev xwm MV tus nqi thaum nruab nrog cov ion xaiv cov hluav taws xob. Ph Metres tau siv dav hauv kev tiv thaiv ib puag ncig, dej pheeb suab, kev tshawb fawb, kev lag luam tshuaj, dej aquaculture, coj mus rhaub dej thiab lwm thaj chaw. Cov twj paj nruag no tseem yog ib qho khoom siv tshuaj ntsuam tseem ceeb rau QS thiab HACCP ntawv pov thawj hauv cov khoom noj khoom haus thiab cov nroj tsuag dej. Hauv qab no yog cov lus qhia luv luv rau cov ntawv thov hom ntawm xov tooj hauv cov ntsuas hauv av hauv av. Nws ntsuas ntau yam thiab precision nyob ntawm tus xaiv E Electrode thiab Ph 'metre. Feem ntau yog qhov tseeb rau 0. 01 PHIB units.
Ntsuas ntsuas lub hauv paus
PH yog ib qho ntawm cov khoom tseem ceeb thiab nquag ua haujlwm hauv cov dej tshuaj xyuas, thiab yog ib qho tseem ceeb rau kev ntsuas dej zoo. Thaum cov dej muaj paug, nws yuav ua rau hloov pauv tseem ceeb hauv PHIC. Thaum dej muaj cov nyiaj ntau ntawm cov pa roj carbon dawb dawb, nws tuaj yeem txo qis ph tus nqi ntawm cov dej.
Cov qauv no siv cov ntawv PHICE rau hauv qhov ntsuas hluav taws xob thiab cov calomel electrode raws li cov ntaub ntawv hluav taws xob, raus hauv kev ntsuas ntsuas hluav taws xob kom tsim cov cell. Ntawm 25 degree, txhua koog ntawm ps tus nqi yog sib npaug rau 59.1MV hloov hauv hluav taws xob quab yuam. Rau txhua 59.1MV hloov hauv hluav taws xob quab yuam, tus nqi ntawm tus nqi ntawm kev daws teeb meem los ntawm ib chav. Tom qab muab txoj haujlwm nrog tus qauv ntas cov tshuaj, muab cov electrode rau hauv cov qauv kom ncaj qha ntsuas tus nqi PHO. Qhov kub sib txawv tuaj yeem kho tau los ntawm qhov ntsuas kub uas tau them rau ntawm qhov ntsuas. Cov xim, cov tshuaj khib nyiab, cov tshuaj colloidal, oxidants, txo cov neeg sawv cev, thiab cov ntsev kom tsawg ntawm cov dej ua piv txwv tsis cuam tshuam nrog kev ntsuas. Tab sis hauv kev daws teeb meem zoo nkauj alkaline, yuam kev tuaj yeem tshwm sim thaum muaj nyiaj ntau ntawm sodium ions yog tam sim no, ua rau nyeem tsawg dua.
Yuav tsum reagents
Yog tias tsis muaj lwm yam lus qhia, cov reagents siv nyob rau hauv hom no yog siv reagents lossis pH cov neeg sawv cev, thiab cov dej siv yog dej distilled lossis dej deionized.
Npaj ntawm PHC cov qauv kev daws teeb meem: hnyav cov nyiaj ntawm reagent rau hauv cov dej npau, thiab thaum muaj dej nyob ntev li 25 degree, dilute nws nrog dej mus rau lub cim thiab co kom zoo. Cov dej deionized yuav tsum tau rhaub kom tshem cov pa roj carbon dioxide ua ntej siv, thiab txias ua ntej siv. Qhov kev tshaj tawm ntawm cov dej deionized yuav tsum tsawg dua 2 μ S / cm, thiab cov ntawv yuav yuav tsum yog nyob nruab nrab ntawm 5.6 thiab 6.0.
