^{2}-alginate biocomposite was synthesized with improved mechanical properties, showing chelation capability of divalent metal ions, especially Cu(II), through its carboxylic acid ends. The biocomposite was characterized using scanning electron microscopy (SEM), Fourier-transform infrared (FTIR), and X-ray photoelectron spectroscopy (XPS) techniques. The adsorption of copper(II) onto both H-...

*Entemorpha linza*was investigated as a function of pH, contact time, biomass dose, and temperature. The experimental data were evaluated by Langmuir, Freundlich, and Dubinin–Radushkevich isotherm models. The uptake capacity of the tested metal ions was markedly influenced by pH in the range of 2–3.5 and maximum...
