Notes:

  • The concentration standards originally prepared were too high in regards to concentration; therefore, the CuSO4 standards between 5-20ppm need to be remade.
  • All Fe3O4 samples need to be prepared and tested because the solutions were prepared in and diluted with CuSO4 instead of distilled H2O
  • Due to various errors regarding concentrations the calibration curve created was inaccurate
  • AA needs to be run again
