Imisebenzi kunye neempawu ze-ammonia nitrogen electrode
1. Ukulinganisa ngokuntywiliselwa ngqo kwiprobe ngaphandle kokuthatha iisampulu kunye nonyango lwangaphambi konyango;
2. Akukho reagent yeekhemikhali kwaye akukho ungcoliseko lwesibini;
3. Ixesha elifutshane lokuphendula kunye nomlinganiselo oqhubekayo okhoyo;
4. Ngokucocwa ngokuzenzekelayo kunciphisa ubuninzi bokugcinwa;
5. Ukhuseleko loqhagamshelo olubuyela umva lwezibonda ezilungileyo nezingalunganga zombane we-sensor;
6. Ukhuseleko lwe-RS485A / B terminal eqhagamshelwe gwenxa kumbane;
7. Imodyuli yokudlulisa idatha engenazingcingo enokukhetha
Uvavanyo lwe-ammonia nitrogen olukwi-intanethi lusebenzisa indlela ye-electrode yokuva igesi ye-ammonia
Isisombululo se-NaOH songezwa kwisampuli yamanzi size sixutywe ngokulinganayo, kwaye silungise ixabiso le-pH yesampuli ubuncinane i-12. Ngoko ke, zonke ii-ion ze-ammonium kwisampuli ziguqulwa zibe yi-NH3 enegesi kwaye i-ammonia ekhululekileyo ingena kwi-electrode yokuva igesi ye-ammonia nge-membrane evulekayo ukuze ithathe inxaxheba kwi-chemical reaction, etshintsha ixabiso le-pH ye-electrolyte kwi-electrode. Kukho ubudlelwane obuchanekileyo phakathi kokwahluka kwexabiso le-pH kunye noxinzelelo lwe-NH3, olunokungcanyulwa yi-electrode kwaye luguqulwe lube luxinzelelo lwe-NH4-N ngumatshini ophetheyo.
Rumjikelo wokutshintshwa kwe-electrode ye-ammonia nitrogen
Umjikelo wokutshintshwa kwe-electrode uya kwahluka kancinci ngokomgangatho wamanzi. Umzekelo, umjikelo wokutshintshwa kwe-electrode esetyenziswa emanzini acocekileyo angaphezulu wahlukile kowe-electrode esetyenziswa kwisityalo senkunkuma. Umjikelo wokutshintshwa ocetyiswayo: kanye ngeveki; Intloko yefilimu etshintshiweyo ingasetyenziswa kwakhona emva kokuvuselelwa. Amanyathelo okuvuselelwa: faka intloko yefilimu ye-ammonia nitrogen etshintshiweyo kwi-citric acid (isisombululo sokucoca) iiyure ezingama-48, emva koko emanzini acocekileyo ezinye iiyure ezingama-48, uze uyibeke kwiindawo ezipholileyo ukuze yomiswe emoyeni. Ubungakanani obongezelelweyo be-electrolyte: tyekisa i-electrode kancinci uze wongeze i-electrolyte ide izalise i-2/3 yentloko yefilimu, uze uyiqinise i-electrode.
Ukulungiswa kwe-electrode ye-ammonium ion
1. Susa isigqubuthelo sokukhusela entlokweni ye-electrode. Qaphela: musa ukuchukumisa nayiphi na indawo ebuthathaka ye-electrode ngeminwe yakho.
2. Kwi-electrode enye: yongeza isisombululo sesalathiso kwi-electrode yesalathiso ehambelanayo.
3. Kwi-electrode edityanisiweyo yokongeza ulwelo: yongeza isisombululo sesalathiso kwindawo yokubeka uphawu kwaye uqinisekise ukuba umngxuma wokongeza ulwelo uvulekile ngexesha lovavanyo.
4. Kwi-electrode edibeneyo engazaliswayo: ulwelo olubhekisayo luyijeli kwaye lutywiniwe. Akukho lwelo lokuzalisa lufunekayo.
5. Coca i-electrode ngamanzi acocekileyo uze uyifunxe yome. Musa ukuyisula.
6. Beka i-electrode kwisibambi se-electrode. Ngaphambi kokuba uyisebenzise, faka isiphelo esingaphambili se-electrode emanzini acocekileyo imizuzu eli-10, uze uyifake kwisisombululo se-chloride ion esixutyiweyo iiyure ezi-2.
