Özet

The removal of Cu (II) ions from aqueous solution by adsorption on nonliving dried pollens of Typha latifolia L. was studied in batch system. Concentrations ranging from 10 to 150 mg l(-1) Cu (II) were tested and metal removal achieved nearly 96 %.The biosorption of Cu (II) ions by pollen was strongly affected by pH. Within the pH range of 4 to 6, the saturated uptake capacity for Cu (II) sorption was 6.23 mg g(-1). In general, higher adsorptive uptake was observed at 20 degreesC. The adsorption of Cu. (II) on pollen appeared to follow the Langmuir adsorption isotherms. Results indicated that nonliving pollen have a high adsorptive capacity for copper.
