Abstract

Polyacrylic acid/polyaniline composite (a three-dimensional cross-linked hydrophilic chelating polymeric sorbent) was improved for promoted recovery of uranium ions from nuclear industrial effluent. The obtained sorbent was physically characterized using scanning electron microscope and Fourier transform infrared spectrometer. The relevant factors were optimized by equilibrium batch experiments using a uranium synthetic nitrate solutions. Desorption of the loaded uranium was approved using 1 M sodium carbonate solution. The practical applicability of the polyacrylic acid/polyaniline composite was then examined upon a uranium nuclear industrial effluent. The experimental results have been studied by both kinetic and sorption isotherm models.
