Lus Cims rau kev siv chloride ion electrode
1. Ua ntej siv, muab tso rau hauv 10-3M Muab cov tshuaj sodium chloride rau hauv lub raj mis kom ua haujlwm li 1 teev. Tom qab ntawd ntxuav nrog dej deionized kom txog thaum lub zog dawb paug yog li + 300mV.
2. Lub electrode siv yog Ag / AgCl hom ob npaugkev sib txuas kuasiv. Tus choj ntsev sab saud puv nrog 3.3MKCI (rkev txhawb nqa nyiaj chloride saturation) thiab tus choj ntsev qis dua yog puv nrog 0.1M sodium nitrate. Yuav kom tiv thaiv cov kua siv los ntawm kev xau sai dhau, thov kaw lub qhov chaw sau nrog daim kab xev nplaum tom qab ntxiv cov kua txhua zaus.
3. Lub electrode yuav tsum tiv thaiv lub diaphragm los ntawm raug khawbor muaj kuab paug. It yuav tsum tsis txhob siv ntev hauv cov tshuaj chloride ion uas muaj cov tshuaj ntau kom tsis txhob muaj xeb ntawm daim nyias nyias ntawm lub electrode. Yog tias qhov chaw ntawm zaj duab xis rhiab heev raug hnav lossis muaj kuab paug, nws yuav tsum tau txhuam rau ntawm lub tshuab txhuam kom hloov kho qhov chaw rhiab heev.
4. Tom qab siv lawm, yuav tsum ntxuav kom huv si kom txog thaum nws muaj peev xwm dawb paug, ziab nrog daim ntawv lim dej thiab khaws cia kom deb ntawm lub teeb.
5. Tus neeg xyuas pib yuav tsum khaws cia kom qhuav.
