放射性核素在固-液界面吸附是其在低浓度下物理化学行为研究的重要内容之一。本文详细介绍了固-液界面吸附研究方面取得的主要进展,对放射性核素在固-液界面的吸附动力学、热力学模型作了简单的介绍,重点讨论了表面配位模型和亚稳态理论在固-液界面吸附行为中的应用和发展,对部分先进光谱技术、理论计算方法和模型模拟手段进行了系统的介绍。

关键词： 放射性核素, 固-液界面, 吸附, 亚稳态理论, 表面配位模型

Sorption of a radionuclide on the solid-liquid interface is one of its most important physicochemical behaviors in environmental medium. Sorption dynamics and thermodynamics research proceedings are introduced in this work. Surface complexation model (SCM) and metastable equilibrium adsorption (MEA) theory are mainly discussed here. In addition, some advanced spectroscopy technologies and modeling methods for surface characterization, theoretical calculations are also introduced detailedly in this paper.

Key words: radionuclide, solid-liquid interface, sorption, MEA, SCM
