Rapid determination of trace amounts of copper, iron and manganese in polyimide resins by graphite furnace atomic absorption spectrometry has been investigated. The standard solutions used were prepared as follows; after evaporating 1 ml of each stock solution(1000 ppm in nitric acid medium), the residue was dissolved in 100 ml of dimethyl formamide. The following procedure was used. Resins 0〜8 g were dissolved in (2〜6) ml of dimethyl formamide, and an aliquot of standard solution of each element was added to it and diluted to 10 ml with dimethyl formamide. A 10μl of the solution was pipetted into graphite furnace atomizer and the atomic absorption signals were measured. The peak height and peak area methods were compared. The peak height values of copper, iron and manganese increased with increasing atomizing temperature, while the peak area values of the three elements approached to a constant value above 2300 ℃ (Cu), 2400 ℃(Fe) and 2200 ℃ (Mn). Calibration curves were linear in the range of 0〜10 ng (peak area method) and 0〜5 ng (peak height method) for the three elements. The standard addition method was used in practical analysis. The standard deviation were (1.8〜4.9)% (Peak area method) and (3.2〜5.9)% (peak height method). The analytical results obtained by the proposed method agreed with those obtained by a dry ashing flame atomic absorption spectrometry. A single determination took about 10min, which was about a twentieth of the time required by a dry ashing flame atomic absorption spectrometry.
