This standard specifies the ion chromatography method for the determination of fluorine, chlorine, nitrite, nitrate and sulfate in atmospheric precipitation. This standard applies to the determination of fluorine, chlorine, nitrite, nitrate and sulfate in atmospheric precipitation samples. The standard input sample volume is: 50μL, and the minimum detection concentrations are: F-0.03mg/L, Cl-0.03mg/L, NO2-0.05 mg/L, NO3-0.10mg/L, SO42-0.10mg/L.
