In this study, chemical modification of MCM-41 mesoporous structure with {3-(2-aminoethylamino) propyl} trimetoxysilane was used as adsorbent for removal of Rhodamine B and Yellow 13. Adsorbent proficiency in removal of basic dyes was studied with parameters such as sorbent mass, pH, contact time and temperature. The results showed that as sorbent mass in 1-6 mg, contact time in 10-60 min, temperature in 25-65 ºC increased; removal of dyes increased in 60-100% in values. Optimal conditions were determined as sorbent mass in 6 mg, contact time in 60 min, temperature in 60 ºC and pH value in 4 and 8 for Rhodamine B and Yellow 13, respectively. Then, its application was investigated on removal of Rhodamine B and Yellow 13 from pharmacy and textile wastes, respectively. The maximum removal values of Rhodamine B and Yellow 13 in wastes using modified MCM-41 were 97.63 and 96.11%, respectively.
