Incorporating Functional Groups on the Structure of Acrylic Fibers for Adsorption of Metal Ionic Compounds

Common commercial acrylic fibers were modified by incorporating different suitable ion adsorbing functional groups into their structures. To study the ion adsorption ability of modified fibers against ionic compounds, the raw fibers were treated with hydroxylamine, hydrazine and urea. The new incorporated functional groups were characterized and appropriate formula for each reaction was suggested. In order to evaluate the ion adsorption capacity of the system, the modified fibers were immersed in separated metal salt solutions. The results show that the samples modified by hydroxylamine, have higher adsorption capacity than others, however, by pretreatment with hydrazine or urea not only the functional groups were increased but also the efficiency of the adsorption was improved.
