Objective

To determine the concentration of Au+3 left unreacted in solution in the fiber solution synthesized on 02/29/12 using electrochemistry.

Description

Determining Concentration of Protein Fibers

  1. Make the following dilutions of chloroauric acid:
    • 5.00 mM
    • 1.00 mM
    • 500 μM
    • 100 μM
    • 50.0 μM
    • 10.0 μM
    • 5.00 μM
    • 1.00 μM
    • 500 nM
    • 100 nM
  2. Add 0.5 mL of 0.5 M KNO3 to each solution.
  3. Run cyclic voltammetry using platinum electrodes as both working and reference electrodes.
  4. Run cyclic voltammetry on fiber solution synthesized on 02/29/12.
