| Outline of Final Research Achievements |
Adsorption of heavy metals onto oxide solids is a crucial process in many fields, such as water treatment, preparation of catalysts. The solid-liquid interfacial phenomena have been explained as surface complex formation between heavy metal ions and surface –OH groups on the solids. However, we found that adsorption can be transformed to sorption, which is assimilating heavy metal ions into the solid’s structure. In this study, we characterized sorption products and revealed the transformation process from adsorption to sorption.
