    • Leaching of palladium was determined by atomic absorption or ICP analysis. For atomic absorption analysis the decanted samples were filtered and furnaced at 400°C, extracted into 3 drops of aqua regia and 3 ml deionised water added. The samples were analysed on a Perkin-Elmer 1100B atomic absorption instrument in conjunction with a series of palladium standards. For inductively coupled plasma (ICP) analysis the decanted samples were filtered and furnaced at 400°C, and extracted into 3 ml dmso-2% HCl solution. The samples were analysed on a Varian Liberty 200 ICP-AES instrument with a series of palladium standards.

    • Davisil 500 Å beads were employed rather than CPG beads as both sets of beads gave comparable yields and palladium leaching. The Davisil beads are more economically viable, and can be purchased from Aldrich Chemicals.
