Treatment of pregnant leachate from uranium contaminated soil
- Los Alamos National Lab., NM (United States); and others
Uranium mining and processing activities have resulted in contamination. Technologies are many sites with uranium from the soil to avoid excavation a needed to effectively extract and separate the uranium and storage costs of the entire volume of soil. Our approach to solving this problem is to use selective chelators to extract the uranium front the soil for reclamation, thus greatly reducing the volume of waste required to be stored. Batch studies have demonstrated that Tiron is an effective chelator for the removal of uranium from contaminated soils. It is highly desirable to recycle the chelator to minimize reduce cost. We have developed an effective method for the recovery of uranium from the pregnant leachate and for recycling Tiron using cation exchange. Through five regenerations, recycled Tiron maintained effectiveness in leaching uranium from soil. This technology is an excellent candidate for treating uranium-contaminated soils.
