Determination of Total Arsenic in Glass by Atomic Fluorescence Spectrometry
Based on the method of determining total arsenic in glass by atomic fluorescence spectrometry,the points for precautions and the selection of experimental conditions in the whole testing process are discussed.Experiments show that the detection limit of this method is low,the detection mass fraction is 1.0×10-5％,the accuracy is high,the recovery rate is 95％～105％,the precision is good,the relative standard deviation of 10 repeated determination is not more than 3.0％.The atomic fluorescence spectrometry method for analysis of total arsenic in glass is especially suitable for the detection of trace arsenic in glass,and can meet demand of detection of total arsenic content in glass industry.
