Phosphoric acid activated carbon as borderline and soft metal ions scavenger

Three activated carbons have been prepared, two from oil-palm shell and one from coconut shell, by the phosphoric acid activation process. Adsorption isotherms of copper(II) were determined to evaluate and compare the performance of experimental carbons. The obtained data are fitted very well to L...
