GB/T 13580.12-1992
ActiveDetermination of sodium andpotassium in the wet precipitation--Atomic absorption spectrophotometry
大气降水中钠、钾的测定 原子吸收分光光度法
Application Summary AI generated
This standard specifies the atomic absorption spectrophotometry method for determining sodium and potassium concentrations in wet precipitation, such as rainwater and snow. It is applied in environmental monitoring and atmospheric chemistry studies to assess the ionic composition of precipitation, particularly for evaluating acid rain and atmospheric deposition. The method is used by environmental laboratories and monitoring stations to ensure accurate measurement of these alkali metals in water samples from natural precipitation events.
