OBJECTIVES
New CuSO4 Dilution Standards for Atomic Absorption
(20 ppm CuSO4)V1 = (0.1 ppm CuSO4)(12mL) V1 = 0.6mL of 20 ppm CuSO4
(20 ppm CuSO4)V1 = (0.5 ppm CuSO4)(12mL) V1 = 1.2mL of 20 ppm CuSO4
(20 ppm CuSO4)V1 = (1 ppm CuSO4)(12mL) V1 = 3mL of 20 ppm CuSO4
(20 ppm CuSO4)V1 = (2 ppm CuSO4)(12mL) V1 = 6mL of 20 ppm CuSO4
(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.
Atomic Absorption NaMT-CuSO4 Exchanged Filtrate Solutions
Fixant Solution Preparation
(Actual Na2SO4 Mass: 199.9953g)
