摘要：
The authors examine the effect of various metal cations on the sorption of a number of acid dyes by PAN fibre. For our studies we used the cations Al**3** plus , Zn**2** plus , and Cr**3** plus and the dyes acid scarlet, acid Bordeaux, and acid anthraquinone green. Based on experimental evidence it has been found that the greatest amount of dye is fixed on the fibre when Al**3** plus ions are introduced into the dye bath. On the basis of analysis of the IR spectra of the dyed fibres, a mechanism has been proposed for the interaction of both the metal cations and also of the dye with PAN fibre.
