Equation
Y = 2.4972x + 1.12R2 = 0.99For Cd (4-100 ng/mL by STAT-AAS)
Y = 0.3278x - 0.2083R2 = 1For Cu (25-400 ng/mL by STAT-AAS)
Y = 85x + 0.5R2 = 0.99For Ni (0.2-2.0 mg/L)
Y = 302x + 0.75R2 = 0.99For Zn (0.1-1.0 mg/L)
Y = 64x + 0.43R2 = 1For Fe (0.20-3.0 mg/L)
Y = 515x + 7.0R2 = 0.99For Mg (0.25-2.0 mg/L)
Y = 305x + 39R2 = 1For Ca (0.25-2.0 mg/L)
