  • Get pXRD data > analysis
  • Rehydrate PVA-Alg-NaMT no citric acid beads in 2 ppm Malachite Green
  • Large scale PVA-Alg-NaMT no citric acid synthesis

Procedure

Procedure adapted from | Kuo-Ying Amanda Wu and Keith D. Wisecarver (1992)<br.> <br.> PVA-Alg-NaMT (no citric acid)

  1. Prepare an aqueous solution of 13% PVA and 0.02% sodium alginate at 60°C (Stir plate on 3rd setting: ~68°C)
    • 1 g of PVA and 0.16 g of sodium alginate in 7 mL of water (12.5% PVA and ~0.02% alginate)
      • Add alginate while stirring PVA-water solution
    • ~0.1 g of NaMT and ~0.05 g AC should be added to this mixture where applicable
  2. Cool dissolved and mixed solution to 35°C
  3. Prepare 210 mL of saturated citric acid with 4% calcium chloride
    1. Add 8.4 g (4%) calcium chloride to 210 mL of water
  4. Add the PVA-Alg-Nanocomposite mixture drop-wise (by syringe) to the gently stirring (stir plate 3) citric acid-calcium chloride solution using a Pasteur pipette
  5. Stir for 2 hrs to allow solidification
  6. Rinse with water to remove excess reactants
