radiofrequency titration

Japanese: radiofrequency titration(英語表記)radiofrequencytitration
radiofrequency titration

...In precipitation titration and complexometric titration, the titration produces poorly soluble salts or poorly dissociable complex salts, which significantly change the conductivity of the solution, allowing the titration end point to be determined with high sensitivity.
[Radiofrequency titration]
A titration cell is combined with a high-frequency tuned circuit to measure the change in solution composition during titration as a characteristic of the oscillator, i.e., a change in oscillation frequency or oscillation intensity, and the titration end point is detected. The titration curve obtained by plotting the amount of standard solution dropped versus the corresponding oscillation frequency bends at the equivalence point. …

…また,沈殿滴定や錯滴定においても,滴定により難溶性塩や難解離性錯塩を生成して,溶液の伝導度が顕著に変化するので,滴定の終点が感度よく決定できる。
[高周波滴定radiofrequency titration]
 滴定セルを高周波同調回路と組み合わせて,滴定にともなう溶液組成の変化を発振器の特性,すなわち発振周波数の変化とか発振強度の変化として測定することによって,滴定の終点を検知する方法。標準液の滴下量と対応する発振周波数を作図して得られる滴定曲線は,当量点で折れ曲がる。…
