Adsorption of copper ions from aqueous solution by dried water lily petioles

This work reports the adsorption of Cu (II) from the aqueous solution by dried water lily petioles. It was done to investigate the effects of contact time and initial sorbate concentration on the adsorption of Cu (II) and also to study the maximum adsorption capacity of Cu (TI) by dried water lily p...
