Potentiometric Titration of Polyelectrolytes
Kobunshi Kagaku, 1958 グリオキシル酸による部分アセタール化ポリビニルアルコール(以下PVAGと略称) の電圧滴定実験を行い, Hermansらが指摘している関係が成立することを認めた。これよりPVAGの解離指数を決定した。ii) 滴定実験より得られる静電自由エネルギー変化から別に報告する取扱を利用して球形と仮定したときの高分子イオン半径の算出を試みた。それによればイオン半径は濃度の上昇とともに著しく減少するという結果を得た。iii) 泳動実験によって決定されるポテンシャルと滴定実験によって与えられるポテンシャルとを比較し, 両者にかなりの差異を認めた。これは前者が表面ポテンシャルを, 後者が高分子イオン内部のポテンシャルの平均値を与えているものと考えることにより一応説明された。

Soil Science Society of America Journal, Volume 90, Issue 1, January/February 2026.Abstract Aluminum (Al) is one of the most abundant elements in soils. As poorly crystalline Al hydroxides are reactive toward soil organic matter (SOM), they are thought to be involved in SOM stabilization. This is also inferred from correlations between soil organic carbon contents and those of Al extracted by acid oxalate in darkness (AOD), although ...

Solution properties of iron(III) complexes with 5-fluorosalicylic acid- spectra, speciation, and redox stability [PDF]
, 2008 Iron(III)-5-fluorosalicylic acid systems were investigated in water by pH potentiometry combined with UV-VIS spectrophotometry. The data revealed that stable aquated mono-, bis-, and tris(5-fluorosalicylato) iron(III) complexes are formed together with ...

Automatic Potentiometric Titrations
Transactions of The Electrochemical Society, 1947 Potentiometric titration procedure is described briefly and the application of the potentiometric method to both analytical and general research work is discussed. Instrumentation for the potentiometric titration is reviewed with particular emphasis on automatic apparatus developments tending to simplify the use of the potentiometric method.

DETERMINATION OF TETRAFLUOROBORATE BY POTENTIOMETRIC TITRATION
Вестник Кемеровского государственного университета, 2015 The new method for determination of tetrafluoroborate by potentiometric titration is presented. The method is based on the hydrolysis of the tetrafluoroborate anion in water solutions and it takes into account the appropriate correction factor.
