Orginal research papers
The bio-sorption of ammonium ions using red marine macroalga <a href="http://ganj.irandoc.ac.ir/articles/803044"><em>Gracilaria persica</em></a> were investigated by response surface methodology. The sorbent was characterized by SEM and FTIR analysis. The influence of various operating parameters such as ammonium concentration (mg L<sup>-1</sup>), initial solution pH and alga biomass dosage (g L<sup>-1</sup>) was optimized using Box–Behnken design. A second-order polynomial model successfully described the effects of independent variables on the ammonium ions removal. At the optimum conditions, the maximum removal efficiency was achieved at 100.01 %. The kinetic results also demonstrated that the bio-sorption of ammonium ions by the dried microalga followed well pseudo-second-order kinetics. FTIR results showed that amide, aliphatic and carbonyl groups might be responsible for the adsorption of ammonium ions in aqueous solution by dried <em>G. persica</em> biomass.
