| Abstract: | The contents of elements K, Na, Ca, Mg in carbon fibre were determined by atomic absorption spectrophotometry. The effects of acid concentration and interfering ions on the determination results were studied. The results showed that this method is a quick, accurate and efficient method. The contents of K, Na, Ca, Mg in rayon carbon fibres after and before purification treatment were determined and compared. The contents of these elements in carbon fibres made from various PAN precursor fibres were also determined and compared. |
