| 1. A process for preparing a rubidium-82 generator, comprising:
preparing sodium nonatitanate from titanium isopropoxide and aqueous sodium hydroxide;
heating the sodium nonatitanate at a temperature between 100° C. and 250° C. for a period between 12 hours and 2 weeks;
lowering the pH of the sodium nonatitanate; and
absorbing strontium-82 on the neutralized sodium nonatitanate from an aqueous solution comprising strontium-82 and a soluble
sodium salt.
