ibipimo bya pHnaibipimo by'ubushobozi bwo gutwara ibinyabizigani ibikoresho bikoreshwa cyane mu bushakashatsi bwa siyansi, kugenzura ibidukikije, no mu mikorere y'inganda. Imikorere yabyo neza no kugenzura ibipimo bishingiye cyane ku bisubizo bikoreshwa. Agaciro ka pH n'ubushobozi bw'amashanyarazi bw'ibi bisubizo bigira ingaruka zikomeye ku ihindagurika ry'ubushyuhe. Uko ubushyuhe buhinduka, ibipimo byombi bigaragaza ibisubizo bitandukanye, bishobora kugira ingaruka ku buryo buboneye bwo gupima. Mu gihe cyo kugenzura ibipimo, byagaragaye ko ikoreshwa nabi ry'ibikoresho bigabanya ubushyuhe muri ibi bikoresho rituma habaho ihinduka rikomeye mu bipimo. Byongeye kandi, bamwe mu bakoresha ntibasobanukirwe amahame shingiro yo gupima ubushyuhe cyangwa ntibamenye itandukaniro riri hagati ya pH n'ibipimo by'ubushobozi, bigatuma ikoreshwa ritari ryo n'amakuru atari ay'ukuri. Kubwibyo, gusobanukirwa neza amahame n'itandukaniro riri hagati y'uburyo bwo gupima ubushyuhe bw'ibi bikoresho bibiri ni ingenzi kugira ngo harebwe ko ibipimo ari ukuri.

I. Amahame n'imikorere by'ibikoresho bigabanya ubushyuhe

1. Gutanga ubushyuhe mu bipimo bya pH
Mu gupima no gukoresha neza ibipimo bya pH, ibipimo bitari byo bikunze guterwa no gukoresha nabi ikigega cy’ubushyuhe. Inshingano y’ibanze y’ikigega cy’ubushyuhe cya pH ni uguhindura ingano y’ibisubizo bya electrode hakurikijwe ikigereranyo cya Nernst, bigatuma hamenyekana neza pH y’igisubizo ku bushyuhe bw’ubu.

Itandukaniro rishoboka (muri mV) rikomoka kuri sisitemu yo gupima electrode rigumaho uko ubushyuhe bwaba buri kose; icyakora, ubushobozi bwo kumenya pH—ni ukuvuga impinduka muri voltage kuri pH—burahinduka bitewe n’ubushyuhe. Igereranya rya Nernst rigena iyi sano, rigaragaza ko imiterere y’igisubizo cya electrode yiyongera uko ubushyuhe buzamuka. Iyo icyuma gitanga ubushyuhe gikozwe, igikoresho gihindura uburyo bwo guhindura ibintu hakurikijwe ubushobozi bwacyo, kikerekana ko pH igaragara ihuye n’ubushyuhe nyakuri bw’umuti. Hatabayeho kwishyura ubushyuhe bukwiye, pH yapimwe yagaragaza ubushyuhe bwagenwe aho kugaragaza ubushyuhe bw’icyitegererezo, bigatera amakosa. Bityo, kwishyura ubushyuhe byemerera gupima pH yizewe mu bihe bitandukanye by’ubushyuhe.

Isesengura rya PH ry'amazi yanduye mu nganda

2. Inyungu ku bushyuhe mu bipimo by'amashanyarazi
Uburyo amashanyarazi atwara amashanyarazi akoresha amashanyarazi bushingiye ku rugero rwa ionization ya electrolytes n'uburyo iyoni zitwara mu gisubizo, byombi bikaba biterwa n'ubushyuhe. Uko ubushyuhe bwiyongera, uburyo iyoni itwara amashanyarazi bugenda bwiyongera, bigatuma agaciro k'uburyo amashanyarazi atwara amashanyarazi kaba hejuru; ku rundi ruhande, ubushyuhe buke bugabanya uburyo amashanyarazi atwara amashanyarazi. Kubera uku kwishingikiriza cyane, kugereranya neza ibipimo by'uburyo amashanyarazi akoreshwa mu bushyuhe butandukanye ntacyo bivuze hatabayeho igenamiterere.

Kugira ngo harebwe ko ibintu bigereranywa, ibipimo by’ubushyuhe bikunze kwerekezwa ku bushyuhe busanzwe—ubusanzwe 25 °C. Iyo icyuma gitanga ubushyuhe kidakora, igikoresho kigaragaza ubushyuhe ku bushyuhe nyabwo bw’igisubizo. Muri ibyo bihe, hagomba gukosorwa n’intoki hakoreshejwe ikigereranyo cy’ubushyuhe (β) gikwiye kugira ngo hahindurwe ibisubizo ku bushyuhe bw’ikigereranyo. Ariko, iyo igikoresho gitanga ubushyuhe gifunguye, igikoresho gihita gikora iri hinduka hashingiwe ku gipimo cy’ubushyuhe cyagenwe mbere cyangwa gishobora guhindurwa n’umukoresha. Ibi bituma habaho igereranya rihoraho mu ngero kandi bigashyigikira kubahiriza amahame ngenderwaho y’inganda. Bitewe n’akamaro kabyo, ibipimo by’ubushyuhe bigezweho hafi ya byose birimo imikorere yo kwishyura ubushyuhe, kandi inzira zo kugenzura ibipimo zigomba kuba zirimo isuzuma ry’iki kintu.

II. Ibipimo by'imikorere ku bipimo bya pH na conductivity hamwe n'ubwishyu bw'ubushyuhe

1. Amabwiriza yo gukoresha ibikoresho bipima ubushyuhe bya pH
Kubera ko ikimenyetso cya mV cyapimwe kidahinduka bitewe n'ubushyuhe, inshingano y'icyuma gitanga ubushyuhe ni uguhindura imiterere y'umusemburo (coefficient K) w'igisubizo cya electrode kugira ngo ihuze n'ubushyuhe bw'ubu. Kubwibyo, ni ngombwa kwemeza ko ubushyuhe bw'ibisubizo bya buffer bikoreshwa mu gihe cyo gupima buhuye n'ubw'icyitegererezo kiri gupimwa, cyangwa ko hakoreshwa uburyo bwo kwishyura ubushyuhe neza. Kutabikora bishobora gutera amakosa mu buryo busanzwe, cyane cyane iyo ingero zipimwe kure y'ubushyuhe bwo gupima.

2. Amabwiriza yo gukoresha ibikoresho bipima ubushyuhe mu gipimo cy'amashanyarazi
Igipimo cyo gukosora ubushyuhe (β) gikora uruhare runini mu guhindura uburyo bwo gupima ubushyuhe bupimwe bujya mu bushyuhe bw'ikigereranyo. Ibisubizo bitandukanye bigaragaza agaciro ka β gatandukanye—urugero, amazi karemano asanzwe aba afite β iri hagati ya 2.0–2.5 %/°C, mu gihe aside cyangwa base zikomeye zishobora gutandukana cyane. Ibikoresho bifite igipimo cyo gukosora gihamye (urugero, 2.0 %/°C) bishobora guteza amakosa mu gupima ibisubizo bitari bisanzwe. Ku ikoreshwa ry’ubuziranenge bwo hejuru, niba igipimo cyubatswemo kidashobora guhindurwa kugira ngo gihuze na β nyayo y’igisubizo, ni byiza guhagarika akazi ko gukosora ubushyuhe. Ahubwo, pima ubushyuhe bw’igisubizo neza kandi ukore ikosora n’intoki, cyangwa ukomeze icyitegererezo kuri 25 °C neza mu gihe cyo gupima kugira ngo ukureho ikibazo cyo gukosora.

III. Uburyo bwihuse bwo gusuzuma imikorere mibi mu bigabanya ubushyuhe

1. Uburyo bwihuse bwo kugenzura ibipimo by'ubushyuhe bya pH
Ubwa mbere, pima igipimo cya pH ukoresheje ibisubizo bibiri bisanzwe bya buffer kugira ngo umenye neza aho uburebure bugarukira. Hanyuma, pima igisubizo cya gatatu cyemewe mu bihe byishyurwa (hamwe n'ubushyuhe butangwa). Gereranya igipimo cyabonetse n'agaciro ka pH gateganijwe ku bushyuhe nyabwo bw'igipimo, nk'uko bivugwa mu "Amabwiriza yo kugenzura kuri metero za pH." Niba ikosa rirenze ikosa ntarengwa ryemewe ku isomo ry'ubuziranenge bw'igikoresho, icyuma gitanga ubushyuhe gishobora kuba kidakora neza kandi gisaba igenzura ry'abahanga.

2. Uburyo bwo kugenzura byihuse ibipimo by'ubushyuhe bipima amashanyarazi
Pima uburyo bwo gutwara umuvuduko n'ubushyuhe bw'umuti uhamye ukoresheje icyuma gipima ubushyuhe gifunguye. Andika agaciro k'uburyo bwo gutwara umuvuduko kagaragajwe. Nyuma yaho, hagarika icyuma gitanga ubushyuhe hanyuma wandike uburyo bwo gutwara umuvuduko ku bushyuhe nyabwo. Ukoresheje igipimo cy'ubushyuhe kizwi cy'umuti, banza ubare uburyo bwo gutwara umuvuduko buteganijwe ku bushyuhe bwa reference (25 °C). Gereranya agaciro kabazwe n'inyuguti y'igikoresho. Itandukaniro rikomeye rigaragaza ikosa rishobora kuba riri muri algorithme yo kwishyura ubushyuhe cyangwa sensor, bigasaba ko hakorwa igenzura ryinshi rikorwa na laboratwari yemewe yo gusuzuma ubushyuhe.

Mu gusoza, imikorere yo kwishyura ubushyuhe muri metero za pH n'ibipimo by'ubushyuhe bigira intego zitandukanye cyane. Muri metero za pH, kwishyura bihindura uburyo electrode ibona ingaruka z'ubushyuhe mu gihe nyacyo hakurikijwe ikigereranyo cya Nernst. Muri metero za conduction, kwishyura bihindura uburyo ibipimo bihinduka ubushyuhe kugira ngo bishobore kugereranya ingero zitandukanye. Guhuza ubu buryo bishobora gutuma habaho ibisobanuro bitari byo no kwangiza ireme ry'amakuru. Gusobanukirwa neza amahame yabwo bituma habaho ibipimo nyabyo kandi byizewe. Byongeye kandi, uburyo bwo gusuzuma bwavuzwe haruguru butuma abakoresha bakora isuzuma ry'ibanze ry'imikorere y'ibipimo. Iyo habonetse ibitagenda neza, ni ngombwa cyane kohereza igikoresho vuba kugira ngo gisuzumwe neza.

Andika ubutumwa bwawe hano hanyuma ubwoherereze
