AWWA JAW10523

In batch experiments described in this paper, 200 mL aliquots of natural and synthetic waters were treated with various amounts of lime, magnesium carbonate, ferric sulfate, and aluminum sulfate. After their pHs were adjusted, these solutions were mixed for 30 minutes, allowed to settle for 2 hours, filtered (20 mL) through a membrane filter, and analyzed for uranium activity. For the anion-exchange treatment, water was passed through a strong base anion-exchange resin. Under optimum conditions, the chemical treatments effectively removed uranium. The anion-exchange resin had a large adsorption capacity and selectivity for uranyl carbonates, the common species of uranium in surface waters and groundwaters. Includes 15 references, tables, figures.
