Preparation of 103Pd seed–molecular plating of 103Pd onto silver rod

A method for 103Pd “molecular plating” onto the surface of a silver rod is reported. The optimal composition of the plating bath is as follows: palladium chloride 0.1 mol/l, formaldehyde 2 mol/l, nitric acid 1 mol/l, and formic acid 0.4 mol/l. The 103Pd molecular plating procedure will last 25 min at 30°C. This article provides a valuable experience for the preparation of 103Pd brachytherapy seed.
