Amakuru - Ni irihe tandukaniro riri hagati ya electrode ya pH y’aho amazi ahurira n’aho amazi ahurira inshuro imwe n’abiri?

Electrode za PH ziratandukanye mu buryo butandukanye; uhereye ku ishusho y'umutwe, aho zihurira, ibikoresho n'aho zizura. Itandukaniro rikomeye ni niba electrode ifite aho zihurira rimwe cyangwa abiri.

Electrode za pH zikora zite?
Electrode za pH zivanze zikora zikoresheje igice cy’uturemangingo (insinga y’ifeza itwikiriwe na AgCl) n’igice cy’uturemangingo (insinga y’amashanyarazi ya Ag / AgCl), ibi bice bibiri bigomba guhuzwa kugira ngo byuzuze umurongo kugira ngo icyuma gipima pH kibone ishusho ya pH. Mu gihe igice cy’uturemangingo cy’uturemangingo cy’uturemangingo cy’uturemangingo kibona impinduka muri pH y’umuti, igice cy’uturemangingo cy’uturemangingo ni ubushobozi buhamye bwo kurebera hamwe. Electrode zishobora kuba zuzuye amazi cyangwa gel. Electrode y’amazi ikora aho ihurira n’agace gato k’umuti wo kuzuza ku mpera y’icyuma. Akenshi zifite imikorere ya pompe igufasha gukora aho ihurira hashya kuri buri gikorwa. Zikeneye kongeramo amazi buri gihe ariko zitanga imikorere myiza yongera igihe cyo kubaho, ubunyangamugayo n’umuvuduko w’igisubizo. Iyo zikomeje, aho ihurira hazaba hari igihe cyo kubaho iteka. Hari electrode zimwe zikoresha electrolyte ya gel idakeneye kongerwaho n’umukoresha. Ibi bituma ziba amahitamo meza ariko bizagabanya igihe cyo kubaho cya electrode kugeza ku mwaka umwe iyo zibitswe neza.

Guhuza Double – izi electrode za pH zifite ikiraro cy’umunyu cy’inyongera kugira ngo zikumire ingaruka hagati y’umuti w’amashanyarazi n’icyitegererezo cyawe byakwangiza ihuriro ry’amashanyarazi. Zisabwa gupima ingero zirimo poroteyine, ibyuma biremereye cyangwa sulfide

Ihuriro ry'amasambu rimwe – ibi ni ibyo gukoreshwa muri rusange ku bipimo bitazahagarika aho amasambu ahurira.

Ni ubuhe bwoko bwa electrode ya pH nkwiye gukoresha?
Iyo icyitegererezo gifite poroteyine, sulfite, ibyuma biremereye cyangwa TRIS buffers, electrolyte ishobora gukorana n'icyitegererezo igashyiraho umwuka ukomeye ufunga aho electrode ihurira ukayihagarika. Iyi ni imwe mu mpamvu zikunze gutera "electrode yapfuye" tubona kenshi.

Kuri izo ngero ukeneye inzira ebyiri zo guhuza ibintu – ibi bitanga uburinzi bw'inyongera kuri ibi, bityo uzabona ubuzima bwiza cyane muri electrode ya pH.
