Here we report on the adsorption performance of calcium alginate (Ca-Alg2) and Ca-Alg2 with encapsulated graphene oxide (Ca-Alg2/GO) gel bead adsorbents for the successful removal of Cu(2+) ions from aqueous solution. Different adsorbent doses, Cu(2+) concentrations and contact times were investigated using equilibrium and kinetic studies. The adsorbents were characterized using Fourier transform-infrared (FT-IR) spectroscopy, thermogravimetric analysis (TGA) and focussed ion beam scanning… CONTINUE READING
