Abtract Objective:To establish a graphite furnace atomic absorption spectroscopy,and to determine the content of aluminum in the hemofiltration base solution.Methods:The standard addition method of atomic absorption of graphite furnace was used to add matrix modifier to determine the content of aluminum.Results:Aluminum has a good linear relationship in the range of 0-20 μg·L-1,r=0.998;The detection limit concentration was 0.91 μg·L-1.The average recovery rate was 96.5％.The results of the three batches were 3.299,1.232 and 2.431 µg·L-1,respectively.Conclution:This method can effectively measure the content of aluminum in hemofiltration base solution products,and control the raw materials,production and packaging of products that may introduce pollution pathways.It is recommended that enterprises pay attention to the detection of aluminum content in the on hemofil-tration base solution to minimize the risk of contamination and ensure the quality of products.
