pH electrode tu thiab tu
1, PH electrode tsis nquag siv, tuaj yeem muab tso rau hauv 3mol / l kcl tov lossis saturated kcl tov, nruj me ntsis txwv tsis pub cov electrode rau hauv dej distilled, dej demineralised lossis kais dej, thiab lwm yam, cov ntsiab lus plasma ntawm cov kua yog me me heev.
2, Yog tias PH electrode tau raug huab cua ntev ntev, ua ntej rov siv dua, thov tsau cov electrode hauv 3mol / l kcl tov los yog saturated kcl tov rau 2 ~ 3 hnub kom cov electrode active dua, yog tias muaj. tej yam kev mob, thov tsau cov electrode nyob rau hauv 9895 electrode regeneration tov rau 1 feeb los yog li ntawd, thiab ces ntxuav nws nrog distilled dej, thiab ces tsau lub electrode nyob rau hauv 3 mol / l kcl tov los yog saturated kcl tov rau tsawg kawg yog 1 hnub ua ntej siv nws. daws yam tsawg kawg 1 hnub ua ntej siv.
3, yog hais tias lub electrode rhiab membrane los yog dawb ceramic diaphragm qhov los ntawm cov kuab paug thiab yellowing, koj muaj peev xwm yuav 9891 electrode tu tov, lub electrode yuav immersed nyob rau hauv nws ob peb teev, thiab ces ntxuav nrog distilled dej, thiab thaum kawg immersed nyob rau hauv 3. mol / l ntawm kcl lossis saturated kcl tov rau yam tsawg 1 hnub ua ntej siv.
4, yog tias lub electrode dawb ceramic diaphragm qhov los ntawm Aq2S cov pa phem thiab dub, koj tuaj yeem yuav 9892 diaphragm ntxuav cov tshuaj, cov electrode yuav muab tso rau hauv ob peb teev kom txog thaum lub qhov diaphragm thiab tom qab ntawd dawb, thiab tom qab ntawd ntxuav nrog dej distilled, thiab thaum kawg. immersed nyob rau hauv 3 mol / l kcl los yog saturated kcl tov rau tsawg kawg yog 1 hnub ua ntej siv.
5, yog tias cov khoom siv hluav taws xob siv tau ntev thiab ua rau cov tawv nqaij rhiab heev, koj tuaj yeem yuav 9895 electrode regeneration tov, cov electrode yuav immersed nyob rau hauv uas 1 ~ 10 feeb (raws li kev laus ntawm cov rhiab membrane thiab txoj kab nqes. ntawm qhov kev txiav txim siab ntawm lub sijhawm immersion), thiab tom qab ntawd ntxuav nrog dej distilled, thiab thaum kawg muab tso rau hauv 3mol / l ntawm kcl thiab saturated kcl tov rau tsawg kawg 1 hnub ua ntej siv, nruj me ntsis txwv tsis pub txoj kab nqes ntawm PH electrodes saum toj no 56mv / ph nrog txoj kab nqes ntawm 56mv / ph, lub electrode yuav siv tsawg kawg yog 1 hnub, cov electrode yuav siv tsis tau. PH electrode nrog txoj kab nqes siab tshaj 56mv / ph yog nruj me ntsis txwv tsis pub ua los ntawm 9895, vim hais tias 9895 electrode regeneration tov muaj HF tov, lub hauv paus ntsiab lus ntawm 9895 yog corrode tawm cov laus txheej ntawm cov rhiab membrane ntawm qhov chaw nrog HF, yog hais tias tus tshiab electrode yog immersed nyob rau hauv 9895 electrode regeneration tov los yog cov qub electrode yog immersed ntev dhau lawm nyob rau hauv nws, HF yuav corrode tawm qhov zoo ntawm cov rhiab membrane ib yam nkaus.
6, yog hais tias tus PH electrode yog paug los ntawm inorganic tshuaj yuav ua tau 0.1 mol / l ntawm Hcl los yog NaOH tov rau ob peb feeb, thiab ces ntxuav nrog distilled dej.
7, yog hais tias tus PH electrode yog paug los ntawm cov organic tshuaj, yuav tsum tau ntxuav nrog cawv los yog acetone, thiab ces ntxuav nrog distilled dej.
8, Yog tias koj paub tias yam khoom twg tuaj yeem siv los ua kom cov khoom ua paug rau cov electrode, koj tuaj yeem siv yam khoom los ntxuav nws.
9, thov nco ntsoov, nrog 9891, 9892 lossis 9895 kho PH electrode, thov tsis txhob ntsuas lossis ntsuas tam sim, vim tias tom qab ntawd cov electrode tsis tuaj yeem ntsuas, koj yuav tsum tsau cov electrode hauv 3 mol / l lossis saturated kcl daws yam tsawg 1. hnub ua ntej siv.
10, PH electrode sab sauv kawg thiab cable txuas yog qhov siab impedance, txwv tsis pub dej thiab lwm yam kua los yog chav thiab lwm yam huab cua yaig, tuaj yeem siv los npog cov electrode tshiab nrog cov txiv ntseej liab me me, electrode cable connectors kuj muaj rau siab impedance. qhov chaw, yog nruj me ntsis txwv tsis pub los ntawm dej thiab lwm yam kua los yog chav thiab lwm yam huab cua yaig, nco ntsoov khaws cia rau hauv qhov chaw qhuav.
