This standard specifies the atomic absorption spectrophotometric method for the determination of calcium and magnesium in atmospheric precipitation. This standard applies to the determination of calcium and magnesium in atmospheric precipitation samples. The minimum detection concentration of this standard is 0.02mg/L for calcium and 0.0025mg/L for magnesium, and the determination range for calcium is 0.2-7mg/L and 0.02-0.5mg/L for magnesium.
