Method Verification for Lead in Soil by Graphite Furnace Atomic Absorption Spectrophotometry
This paper uses graphite furnace atomic absorption spectrophotometry to determine the elements of lead in the soil.The measurement process and measurement results of lead is respectively elaborated,and finally a summary discussion and analysis are carried out.The results show that the detection limit,precision,accuracy and recovery rate of the lead meet the relevant requirements,and meet the requirements of"Soil quality--Determination of lead,cadmium--Graphite furnace atomic absorption spectrophotometry"(GB/T 17141-1997)[1].
