| Research Abstract |
Highly selective separation of oxoanion forming elements such as V, Mo, W, Nb, and Ta from over 20 elements adsorbed IDA resin by using H_2O_2 was established. Especially, V, Mo, and W are designated as stockpiled mineral species by Japanese Government. Since the method provides a selective separation of these elements from many elements in one-step process, this will be a useful method for recycling of them from industrial wastes.
