New adsorptive composite membrane from recycled acrylic fibers and Sargassum dentifolium marine algae for uranium and thorium removal from liquid waste solution

Novel adsorption Algal polymer composite membrane composed of acrylic fiber wastes and grinded marine algae; Sargassum dentifolium was newly prepared using inversion precipitation technique. The adsorption of uranium and thorium from their waste solution was evaluated. The results indicated that the sorption capacities for U and Th were 62 and 59.4 (mg g^-1), respectively, within short time. Adsorption experimental data demonstrated that both metal ions were well fitting with Langmuir isotherm and pseudo-second order kinetics model. The reusability of the composite membrane indicates the stability and efficiency of it in U and Th removal from waste solution. (author)
