چکیده
A simple method has been developed for the preconcentration of copper(II) based on the adsorption of its Modified nano polyacrylonitrile fiber. Modified nano polyacrylonitrile fiber (PANF) was prepared by adding of acrylic fibers to mSethanolamine (MMA) with different concentration solutions. The stability of a chemically Modified nano polyacrylonitrile fiber especially in concentrated hydrochloric acid which was then used as a recycling and pre-concentration reagent for further uses of modified nano polyacrylonitrile fiber. The application of this Modified nano polyacrylonitrile fiber for sorption of a series of metal ions was performed by using different controlling factors such as the pH of metal ion solution and the equilibration shaking time by the static technique. Cu (II) was found to exhibit the highest affinity towards extraction by these Modified nano polyacrylonitrile fiber phases. The pronounced selectivity was also confirmed from the determined distribution coefficient (Kd) of all the metal ions, showing the highest value reported for Cu (II) to occur by Modified nano polyacrylonitrile fiber. The potential applications ofModified nano polyacrylonitrile fiber for selective extraction of Cu(II) to occur from aqueous solution were successfully accomplished as well as pre- concentration of low concentration of Cu(II) (60 pg ml-1) from natural tap water with a pre-concentration factor of 100 for Cu(II) off-line analysis by flame atomic absorption analysis.
