摘要：
A chromium (III) oxide-hydroxide colloid film has been used to model the passive surface of stainless steel in in situ ATR-IR studies of oxalate ion adsorption from aqueous oxalate solutions over a wide pH range. Studies of time and pH dependence of adsorption have been used to reveal a mechanism of adsorption proceeding through ionic, hydrogen bonded and coordinated oxalate species. A Langmuir adsorption constant of 4.5 x 10(4) M-1 was determined for the surface coordinated oxalate from an adsorption isotherm at pH = 3. (C) 1999 Elsevier Science B.V. All rights reserved.
