摘要：
A process for producing technetium-99m from a molybdenum-100 metal powder, comprising the steps of: irradiating in a substantially oxygen-free environment, a hardened sintered target plate coated with a Mo-100 metal, with protons produced by a cyclotron； (ii) dissolving molybdenum ions and technetium ions from the irradiated target plate with an H2O2 solution to form an oxide solution； (iv) raising the pH of the oxide solution to about 14； (v) flowing the pH-adjusted oxide solution through a resin column to immobilize K[TcO4] ions thereon and to elute K2[MoO4] ions therefrom； (vi) eluting the bound K[TcO4] ions from the resin column； (vii) flowing the eluted K[TcO4] ions through an alumina column to immobilize K[TcO4] ions thereon； (viii) washing the immobilized K[TcO4] ions with water； (ix) eluting the immobilized K[TcO4] ions with a saline solution； and (x) recovering the eluted Na[TcO4] ions.
