Abstract: | The effect of arsenate and phosphate ions on the adsorption and color reaction of uranium(VI) with Arsenazo III on the solid phase of a fibrous material filled with the EDE-10p anion exchanger was studied in different adsorption processes. We selected the optimum conditions for the system of U(VI)-AsO 4 3? (H2PO 4 ? )-PANV-EDE-10p-Arsenazo III and used this system for the adsorption-spectrophotometric determination of (0.03–0.3) 10?3 M arsenate, (0.004–0.06) 10?3 M phosphate, and 0.01–0.1 μg/mL uranyl ions. |
