The method and conditions of determining trace arsenic in glue with graphite furnace atomic absorption spectrometry were explored. The best determination conditions: The medium is 4% nitric acid solution. 20μɡ nickelous nitrate is used as basal body modifier. The best cinefaction temperature is 1 000℃. The best atomization temperature is 2 200℃. Detection limit is 1.0×10-12g. Relative standard deviation is 5.7%. Percent recovery is 97%. The method had little detection limit and good accuracy, repeatability. It is a good way of determining trace arsenic in glue.
