Enhanced Uranium Immobilization by Phosphate Amendment under Variable Geochemical and Flow Conditions: Insights from Reactive Transport Modeling.

Abstract

Phosphate amendment has shown promise for enhancing uranium immobilization. The mechanism of the enhancement, however, has remained unclear with contrasting observations under variable environmental conditions. A dual-domain reactive transport model is developed here with constraints from batch and column experimental data to understand the mechanisms and… (More)
