摘要: Variation of the equilibrium uptake cationic dyes with pH has shown that sulfonic groups in polyacrylonitrile fibers behave as weak acids. Deviations experimental results from a Langmuir-type relation derived for competition between different cations limited number anionic sites could be explained by electrostatic repulsive interactions sites. What appeared to favorable were attributed partial covalent character bond dye and sulfonate group.
