CS6510 Fluoride Ion Sensor

ʻO ka wehewehe pōkole:

ʻO ka fluoride ion selective electrode he electrode koho e pili ana i ka manaʻo o ka fluoride ion, ʻo ka mea maʻamau ka lanthanum fluoride electrode.
ʻO Lanthanum fluoride electrode kahi mea ʻike i hana ʻia me ka lanthanum fluoride hoʻokahi aniani i hoʻopaʻa ʻia me ka europium fluoride me nā lua lattice e like me ka mea nui. Loaʻa i kēia kiʻi aniani nā hiʻohiʻona o ka neʻe ʻana o ka fluoride ion i loko o nā lua lattice.
No laila, he maikaʻi loa ka ion conductivity. Ke hoʻohana nei i kēia membrane kristal, hiki ke hana i ka electrode ion fluoride ma ka hoʻokaʻawale ʻana i ʻelua mau hopena ion fluoride. Loaʻa i ka mea ʻike ion fluoride ka coefficient koho o 1.
A aneane ʻaʻohe koho o nā ion ʻē aʻe i loko o ka hopena. ʻO ka ion wale nō me ke keakea ikaika ʻo OH-, ka mea e hana me ka lanthanum fluoride a pili i ka hoʻoholo ʻana o nā ion fluoride. Eia naʻe, hiki ke hoʻololi ʻia no ka hoʻoholo ʻana i ka pH sample <7 e pale aku i kēia keakea.
