pH metresfuthiconductivity metresasetshenziswa kabanzi amathuluzi okuhlaziya ocwaningweni lwesayensi, ukuqapha imvelo, kanye nezinqubo zokukhiqiza zezimboni. Ukusebenza kwawo okunembile nokuqinisekiswa kwe-metrological kuncike kakhulu kuzixazululo zenkomba ezisetshenziswayo. Inani le-pH kanye nokusebenza kukagesi kwalezi zixazululo kuthonywa kakhulu ukuhlukahluka kwezinga lokushisa. Njengoba izinga lokushisa lishintsha, womabili amapharamitha abonisa izimpendulo ezihlukile, ezingathinta ukunemba kokulinganisa. Phakathi nokuqinisekiswa kwe-metrological, kuye kwaphawulwa ukuthi ukusetshenziswa okungalungile kwezinxephezelo zokushisa kulawa mathuluzi kuholela ekuphambukeni okukhulu emiphumeleni yokulinganisa. Ngaphezu kwalokho, abanye abasebenzisi abaziqondi kahle izimiso eziyisisekelo zesinxephezelo sezinga lokushisa noma bayehluleka ukubona umehluko phakathi kwe-pH namamitha wokusebenza, okuholela ekusetshenzisweni okungalungile nedatha engathembekile. Ngakho-ke, ukuqonda okucacile kwezimiso kanye nomehluko phakathi kwezinqubo zokunxeshezelwa kwezinga lokushisa zalawa mathuluzi amabili kubalulekile ukuze kuqinisekiswe ukunemba kokulinganisa.

I. Izimiso kanye Nemisebenzi Yezinxephezelo Zezinga Lokushisa

1. Isinxephezelo Sezinga Lokushisa Kumamitha e-pH
Ekulinganisweni nasekusetshenzisweni okungokoqobo kwamamitha we-pH, izilinganiso ezingalungile ngokuvamile zivela ekusetshenzisweni okungafanele kwesinxephezelo sezinga lokushisa. Umsebenzi oyinhloko wesinxephezelo sezinga lokushisa imitha ye-pH ukulungisa i-coefficient yempendulo ye-electrode ngokuya ngesibalo se-Nernst, okunika amandla ukunqunywa okunembile kwe-pH yesixazululo kuzinga lokushisa lamanje.

Umehluko ongase ube khona (ku-mV) owenziwe uhlelo lwe-electrode yokulinganisa uhlala unjalo kungakhathaliseki izinga lokushisa; Nokho, ukuzwela kokusabela kwe-pH—okungukuthi, ukushintsha kwamandla kagesi ngeyunithi ngayinye ye-pH—kuyahlukahluka ngezinga lokushisa. I-equation ye-Nernst ichaza lobu budlelwano, ikhombisa ukuthi ukuthambekela kwethiyori kwempendulo ye-electrode kuyenyuka ngezinga lokushisa elikhuphukayo. Uma isinxephezelo sezinga lokushisa sisebenza, ithuluzi lilungisa isici sokuguqula ngokufanele, iqinisekise ukuthi inani le-pH elibonisiwe lihambisana nezinga lokushisa langempela lesixazululo. Ngaphandle kwesinxephezelo sezinga lokushisa esifanele, i-pH elinganisiwe izobonisa izinga lokushisa elilinganiselwe kunesampula lokushisa, okuholela kumaphutha. Ngakho-ke, isinxephezelo sezinga lokushisa sivumela ukukalwa okuthembekile kwe-pH kuzo zonke izimo ezishisayo ezishisayo.

2. Isinxephezelo Sezinga Lokushisa Kumamitha Okuqhuba
I-conductivity kagesi incike ezingeni le-ionization yama-electrolyte kanye nokuhamba kwama-ion esixazululweni, kokubili okuncike ekushiseni. Njengoba izinga lokushisa likhuphuka, ukuhamba kwe-ionic kuyanda, okuholela emazingeni aphezulu e-conductivity; ngokuphambene, amazinga okushisa aphansi anciphisa ukusebenza. Ngenxa yalokhu kuncika okuqinile, ukuqhathaniswa okuqondile kwezilinganiso ze-conductivity ezithathwe kumazinga okushisa ahlukene akusho lutho ngaphandle kokumiswa.

Ukuqinisekisa ukuqhathanisa, ukufundwa kwe-conductivity kuvame ukubhekiselwa kumazinga okushisa ajwayelekile—ngokuvamile angama-25 °C. Uma isinxephezelo sezinga lokushisa sikhutshaziwe, ithuluzi libika ukuqhutshwa kwezinga lokushisa lesixazululo langempela. Ezimweni ezinjalo, ukulungisa mathupha kusetshenziswa i-temperature efanelekile (β) kufanele kusetshenziswe ukuguqula umphumela ube izinga lokushisa eliyireferensi. Nokho, uma isinxephezelo sezinga lokushisa sinikwe amandla, ithuluzi lenza lokhu kuguqulwa ngokuzenzakalelayo ngokusekelwe ku-coefficient yezinga lokushisa echazwe ngaphambilini noma elungiseka umsebenzisi. Lokhu kunika amandla ukuqhathanisa okungaguquguquki kuwo wonke amasampuli futhi kusekela ukuhambisana namazinga okulawula emboni ethile. Uma kubhekwa ukubaluleka kwayo, amamitha wokusebenza wesimanje cishe ahlanganisa ukusebenza kwesinxephezelo sezinga lokushisa, futhi izinqubo zokuqinisekisa i-metrological kufanele zibandakanye ukuhlolwa kwalesi sici.

II. Ukucatshangelwa kokusebenza kwe-pH kanye namamitha okuqhuba anesinxephezelo sezinga lokushisa

1. Imihlahlandlela Yokusebenzisa Izinxephezelo Zezinga Lokushisa Lemitha ye-pH
Njengoba isignali ye-mV elinganisiwe ingahlukani nezinga lokushisa, indima yesinxephezelo sezinga lokushisa iwukushintsha umthamo (i-conversion coefficient K) yempendulo ye-electrode ukuze ifane nezinga lokushisa lamanje. Ngakho-ke, kubalulekile ukuqinisekisa ukuthi izinga lokushisa lezixazululo zebhafa elisetshenziswa ngesikhathi sokulinganisa lifana nesampula elilinganiswayo, noma ukuthi kusetshenziswa isinxephezelo esinembile sokushisa. Ukwehluleka ukwenza kanjalo kungase kubangele amaphutha esimiso, ikakhulukazi uma kulinganiswa amasampula kude nezinga lokushisa lokulinganiswa.

2. Imihlahlandlela Yokusebenzisa Izinxephezelo Zemitha Yezinga Lokushisa Le-Conductivity
I-coefficient yokulungisa izinga lokushisa (β) idlala indima ebalulekile ekuguquleni izinga lokushisa elilinganisiwe libe izinga lokushisa eliyireferensi. Izixazululo ezihlukene zibonisa amanani ahlukene ka-β—isibonelo, amanzi emvelo ngokuvamile ano-β cishe ongu-2.0–2.5 %/°C, kuyilapho ama-asidi aqinile noma izisekelo zingahluka kakhulu. Amathuluzi anama-coefficients okulungisa angaguquki (isb, 2.0 %/°C) angase ethule amaphutha lapho akala izixazululo ezingajwayelekile. Ngezinhlelo zokusebenza ezinemba okuphezulu, uma i-coefficient eyakhelwe ngaphakathi ingakwazi ukulungiswa ukuze ifane no-β wangempela wesixazululo, kuyanconywa ukukhubaza umsebenzi wokunxeshezelwa kwezinga lokushisa. Kunalokho, linganisa izinga lokushisa lesixazululo ngokunembile futhi wenze ukulungisa mathupha, noma gcina isampula liku-25 °C ncamashi phakathi nokulinganisa ukuze ukhiphe isidingo sesinxephezelo.

III. Izindlela Zokuxilonga Ezisheshayo Zokuhlonza Ukungasebenzi Kwezinxephezelo Zezinga Lokushisa

1. Indlela Yokuhlola Ngokushesha Yezinxephezelo Zezinga Lokushisa Lemitha ye-pH
Okokuqala, linganisa imitha ye-pH usebenzisa izixazululo ezimbili zebhafa ezijwayelekile ukuze uthole umthambeka olungile. Bese, ulinganisa isisombululo sesithathu esiqinisekisiwe esijwayelekile ngaphansi kwezimo ezinxeshezelwe (ngesinxephezelo sezinga lokushisa esinikwe amandla). Qhathanisa ukufundwa okutholiwe nevelu ye-pH elindelwe ezingeni lokushisa langempela lesixazululo, njengoba kucaciswe "Kumthethonqubo Wokuqinisekisa Wamamitha e-pH." Uma ukuchezuka kudlula umkhawulo wephutha elivumelekile lesigaba sokunemba sethuluzi, isinxephezelo sezinga lokushisa singase singasebenzi kahle futhi sidinga ukuhlolwa kochwepheshe.

2. Indlela Yokuhlola Esheshayo Yezinxephezelo Zemitha Yezinga Lokushisa Ye-Conductivity
Linganisa i-conductivity kanye nezinga lokushisa kwesisombululo esizinzile usebenzisa imitha ye-conductivity ngesinxephezelo sokushisa esinikwe amandla. Rekhoda inani le-conductivity elinxeshezelwe elibonisiwe. Ngokulandelayo, khubaza isinxephezelo sezinga lokushisa futhi urekhode i-conductivity eluhlaza ezingeni lokushisa langempela. Usebenzisa i-coefficient yezinga lokushisa elaziwayo lesixazululo, bala ukuqhutshwa okulindelekile kumazinga okushisa ereferensi (25 °C). Qhathanisa inani elibaliwe nokufunda okunxeshezelwe kwethuluzi. Umehluko omkhulu ubonisa iphutha elingaba khona ku-algorithm yesinxephezelo sezinga lokushisa noma inzwa, edinga ukuqinisekiswa okwengeziwe ngelebhorethri ye-metrology eqinisekisiwe.

Sengiphetha, imisebenzi yesinxephezelo sezinga lokushisa kumamitha we-pH namamitha wokusebenza kufeza izinjongo ezihluke kakhulu. Kumamitha e-pH, isinxephezelo silungisa ukuzwela kwempendulo ye-electrode ukuze ibonise imiphumela yezinga lokushisa lesikhathi sangempela ngokuya ngesibalo se-Nernst. Kumamitha we-conductivity, isinxephezelo senza ukufundwa kujwayeleke kuzinga lokushisa eliyireferensi ukuze kuvunyelwe ukuqhathanisa kwamasampula ahlukahlukene. Ukudida lezi zindlela kungaholela ekuchazeni okuyiphutha kanye nekhwalithi yedatha esengozini. Ukuqonda okuphelele kwezimiso zabo kuqinisekisa izilinganiso ezinembile nezithembekile. Ukwengeza, izindlela zokuxilonga ezichazwe ngenhla zivumela abasebenzisi ukuthi benze ukuhlola kokuqala kokusebenza kwesinxephezelo. Uma kwenzeka kutholwa noma yikuphi okudidayo, ukuthunyelwa ngokushesha kwethuluzi lokuqinisekiswa okusemthethweni kwe-metrological kuyelulekwa ngokuqinile.

Bhala umlayezo wakho lapha futhi usithumelele wona
