OBJECTIVES
Preparations For CuSO4 Clay Exchanged Solutions & Vacuum Filtration ProceduresSetup of a vacuum filtration system: * Clean 250mL Erlenmeyer Filter Flask * Large Buchner Funnel * Whatman #42 Filter Paper * Long Secure Rubber Hose
REPEAT THE PROCEDURE ABOVE FOR THE 100% CEC NaMT, 50% CEC NaMT, & 2:1 Fe3O4 CLAYS AS WELL Atomic Absorption CuSO4 Clay Exchanged Dilutions & CalculationsCuSO4 Dilution Standards 12mL 7.4 ppm CuSO4 requires: (636ppm CuSO4)V1 = (7.4ppm CuSO4)(12mL) V1 = 0.140mL 12mL 10 ppm CuSO4 requires: (636ppm CuSO4)V1 = (10ppm CuSO4)(12mL) V1 = 0.189mL
Atomic Absorption ResultsAtomic Absorption Data and Calibration Curve Data from AA wizard:
