    • note
    • Usually about 83% of Iron Oxide-Pd (based on the weights) could be separated from resins via a magnetic concentration step. However, repeated magnetic separation steps were needed to ensure complete removal of Iron Oxide-Pd out of resins. A picture of magnetic concentration using a permanent magnet is included in the Supporting Information. During magnetic separation, the mixture was then vigorously shaken followed by applying an external permanent magnet. Iron Oxide-Pd was accumulated on the sidewall of a cuvette. Excessive borate and suspended resins in solution were transferred out of the cuvette by using a pipet.
