The progress of the adsorption process was monitored and various adsorption parameters were evaluated. The experiments were conducted to determine the pH profiles, time dependencies and capacities of copper uptake. https://www.biotech-asia.org/vol4no2/removal-of-copper-ii-ions-by-adsorption-onto-crosslinked-calcium-alginate-beads/ Sorption; adsorption isotherms; calcium alginate; immobilization
