Procedure

Indium foil (226.3 mg) is dissolved in HCl and diluted with H2O to give 1.97×103 mol per 100 ml in 0.6 N HCl. Indium citrate solution is prepared by mixing 5 ul of 1.97×10-2M InCl3 (9.85×10-8 mol) with 94 ul of 0.1M ammonium citrate, pH 5.58 to give 9.85×10-4M indium citrate after addition of 1 ul of 111In (13 uCi) in 0.1M ammonium citrate.
