Versuchsvorschrift

Potassium arabinonate (15 mmoles) was dissolved in 20 mL of water. The arabinonate was acidified to approximately 50% neutralization by adding cation exchange resin (Amberlite IRC747 H+ form) and lowering the pH from 8.4 to 3.5. The arabinonate was filtered to remove the resin, diluted to 30 mL, and transferred to a glass cell for electrolysis. The initial arabinonate was quantified by HPLC-RI against an arabinonate standard and was found to contain 9.2 mmoles (0.37 M). There was a loss of 3.3 mmoles of arabinonate from the cation exchange resin.
