Targetry of natSn-target on Cu substrate was investigated for the production of 117,118m,119,120m,122Sb. The electrodeposition experiments were carried out using potassium stannate trihydrate and potassium hydroxide. The optimum conditions of the electrodeposition of tin were as follows: 40 g/L natSn, temperature 75°C and current density (dc) used throughout of 50 mA/cm2. The deposited target was irradiated at 160 ěA current and 16 MeV proton beam (10 min). Separation of no-carrier-added (nca) 117,118m,119,120m,122Sb from the irradiated natSn target hydrochloric solution was investigated using silica-gel column chromatography.
