Author(s): Somayeh Rahdar, Shahin Ahmadi, Hossien Shahraki Zadeh

This study was aimed at investigating Adsorptive removal of Aniline from aqueous solutions using Prunus dulcis. The effect of different parameters such as pH, contact time, pollutant concentration and adsorbent dose was studied in absorption process. The biosorption data have been analyzed using Langmuir, Freundlich and Temkin isotherms. The process of aniline absorption on P. dulcis was depended on Freundlich (R2=0.938) absorption isotherm more than other isotherms. Synthesis of aniline absorption on modified Almond followed on pseudo second- order model. The ΔH◦ and the ΔS° changes were determined as 5.150 kJ/mol-1 and 0.0178 kJ/Mol-1/K-1 respectively. The results showed that Baneh could consider as an effective and cheap absorber in removing the aniline from aqueous solution.
