Objectives

  1. Run AA of all solutions prepared up to this point. This is to determine the amount of Fe remaining in solution after synthesis of magnetic nanoparticles
  2. Attempt preparation of magnetite nanoparticles with gold to produce fibers using new synthetic protocol.


AA Standard Preparations

  • Because AA is destructive 10mL of each sample will be prepared.
  • 5 standard solutions (25μg/mL, 20μg/mL, 15μg/mL, 10μg/mL, 5μg/mL) will be prepared.


General Protocol:

  1. Add the necessary volume of AA/ICPMS 1000 (±) 10 μL/mL, 10% HCl gold solution to a clean 10mL volumetric flask.
  2. Fill the volumetric flask to the line with deionized H2O. Cap and shake the volumetric flask for ~2min.
  3. Pour the gold solution into a falcon tube for storage. Parafilm the cap of the falcon tube to ensure no H2O evaporates.
