Abstract

Proton titration experiments have been conducted at the Idaho National Engineering and Environmental Laboratory on synthetic goethite and soil in an effort to develop adsorption parameters that will help predict migration of radioactive liquid waste. This is the initial step in a reactive transport project to understand contaminant migration in a system characterized by strong chemical gradients. For this stage, two levels of pretreatment were applied to the soil to remove carbonate minerals and soluble salts to focus on the remaining mineral fraction. Without some sort of treatment or conditioning, native soil has a large buffer capacity that interferes with proton titration experiments. In this report, results are presented from the initial stages of the project.
