Abstract
A study on the adsorption properties of seacell fibers for copper and zinc ions used aqueous solutions of copper chloride and zinc sulfate to treat the fibers under various treatment conditions of different times and temperatures.The adsorption capacities of the fibers for copper and zinc ions were determined after measuring the changes of the copper and zinc ion concentrations in the treatment solution.Results showed that because the seaweed particles with rich alginic acid dispersed in the fibers,seacell fibers had good adsorption properties for both copper and zinc ions,with the equilibrium adsorption capacities for copper and zinc ions at about 7 mg/g and 2 mg/g,respectively.The adsorption of copper and zinc ions by seacell fibers is a relatively fast process,with most of the adsorption completed within 0.5 h.It is possible to prepare seacell fibers containing different amounts of copper and zinc ions by controlling the copper and zinc ion concentrations in the treatment solution.
