This standard specifies the determination of potassium and sodium ions in various waters by atomic absorption spectrophotometry. This standard is applicable to the determination of potassium ions and sodium ions in coal mine industrial water, domestic water, surface water, groundwater, and wastewater. When 50mL of test water sample is taken, the concentration range of potassium and sodium ions measured is 0.20~4.0mg/L. Diluting water samples can expand the measurement range.
