Nickel Standard solution preparation
Nickel Standard Solution (10 ppm Ni):Immediately before use, dilute with water to 100 times its volume a solution containing nickel sulfate equivalent to 4.78 g of NiSO4,7H2O in 1000.0 mL.
Nickel Standard Solution (5 ppm Ni):
Immediately before use dilute nickel standard solution (10 ppm Ni) to twice its volume with water.
Nickel Standard Solution (0.2 ppm Ni):
Immediately before use, dilute nickel standard solution (10 ppm Ni) to 50 times its volume with water.
Nickel Standard Solution (0.1 ppm Ni):
Immediately before use, dilute nickel standard solution (10 ppm Ni) to 100 times its volume with water.
