Abstract

Adsorption of some catecholamines from aqueous solutions on a titanium dioxide surface has been studied as depending on pH and sorbent concentration. The experimental data have been interpreted in terms of the surface complexation theory. Stability constants have been calculated for the inner-sphere covalent complexes resulting from the interaction of hydroxyl groups of catecholamines with functional groups of titanium dioxide.

纳米二氧化钛表面上对儿茶酚胺的吸附

摘要

已经研究了根据pH和吸附剂浓度从水溶液在二氧化钛表面上吸附一些儿茶酚胺。实验数据已经根据表面络合理论进行了解释。已经计算出由于儿茶酚胺的羟基与二氧化钛的官能团的相互作用而产生的内球共价配合物的稳定性常数。
