TiO_2-KNO_3溶液界面吸附K^+和NO_3^-的本征络合常数

Determination of Intrinsic Complexation Constants of NO_3^- and K^+ at TiO_2-KNO_3 Aqueous Interface

根据TiO2 表面羟基二元酸的假定 ,应用电位滴定实验数据 ,利用外推作图法求出了TiO2 表面吸附K+和NO3- 的本征络合常数。该数据不仅反映了TiO2 对电解质离子的络合能力 ,也反映了其表面酸性。

Intrinsic complexation constants of NO 3 - and K + at TiO 2-KNO 3 aqueous solution interface are determined, which show not only the acidity of TiO 2, but also the strength of complexation of the ions
