Stability of Ascorbic Acid in Infusion Solution II

Effect of Some Metal Ions on the Producing Hydrogen Peroxide in Some Infusion Solutions added Otsuka MV and Multamin^®

Abstract

In our previous report, we showed that producing hydrogen peroxide increased on standing in infusion solution to which was added multivitamins. Likewise, producing hydrogen peroxide increased on standing after mixing, increasing to 6.76 ppm with the combination of KN solution MG3 with Otsuka MV and to 6.65 ppm with the combination of Solita T^®-4 with Multamin^®. The Zn²⁺ and Mn²⁺ metal ions showed a little effect on the degradation of ascorbic acid (AsA) in spite of the shield, whereas Cu²⁺ remarkably promoted AsA degradation.
