Abstract The macroreticular chelating resins containing amidoxime groups (RNH) showed high affinity for V(V), and were a high capacity of 2.30 mmol/g‐R at pH 5. In particular, it was found that RNH, which were prepared by using 10–16 mol% of DVB in the presence of toluene (80–100 vol%), exhibited the highest adsorption ability for V(V) in a dilute solution. When RNH exhibited the sufficient adsorption ability for V(V), the average pore radius, specific surface area, and pore volume were found to be 140–160 Å, 40–91 m 2 /g, and 0.26–0.36 ml/g, respectively. Vanadium adsorbed on RNH could be eluted by the treatment with 1 M sodium hydroxide solution.
