摘要：
The possibility of using new anion-exchange resins AM-4VP, AM_pu, AMP-p, AM-p, and AM-2B produced by Smoly Group of Enterprises for plutonium recovery from nitric acid process solutions was examined. The physicochemical characteristics of the resins, the thorium distribution coefficients as functions of the nitric acid concentration, and the static exchange capacities of the resins were determined. The plutonium recovery from process solutions was studied in column experiments. The physicochemical properties and sorption ability of the anion-exchange resins were compared to those of the previously used VP-1Ap resin. AM-4VP resin shows promise for plutonium recovery from nitric acid process solutions.
