OBJECTIVES

  • Prepare new CuSO4 standards for Atomic Absorption
  • Re-examine NaMT-CuSO4 exchanged filtrate solutions using Atomic Absorption
  • Crosslink all porphyrin films prepared
  • Prepare new crosslinking fixant solutions

New CuSO4 Dilution Standards for Atomic Absorption

  • Solution 0.1 ppm CuSO4
  (20 ppm CuSO4)V1 = (0.1 ppm CuSO4)(12mL)
   V1 = 0.6mL of 20 ppm CuSO4
  • Solution 0.5 ppm CuSO4 requires
  (20 ppm CuSO4)V1 = (0.5 ppm CuSO4)(12mL)
   V1 = 1.2mL of 20 ppm CuSO4
  • Solution 1 ppm CuSO4 requires
  (20 ppm CuSO4)V1 = (1 ppm CuSO4)(12mL)
   V1 = 3mL of 20 ppm CuSO4
  • Solution 2 ppm CuSO4 requires
  (20 ppm CuSO4)V1 = (2 ppm CuSO4)(12mL)
   V1 = 6mL of 20 ppm CuSO4
  • Solution 3 ppm CuSO4 requires
  (20 ppm CuSO4)V1 = (3 ppm CuSO4)(12mL)
   V1 = 9mL of 20 ppm CuSO4

Using the following concentrations(shown above), a calibration curve was prepared.
