چکیده

Re moval of Acid orange7 from aqueous solution using the mesoporous MCM-41 silica functionalized withdiamine group (NH2- MCM-41) was investigated.This experimental study was done in samples of synthetic and real wastewater from kerman kavir baf Sarir fa ctory within six months. The modification of mesoporous MCM-41 materials by grafting diamine functional groups directly to the su rface of a solid adsorbent was studied. The structure of the synthesis materials was characterized by XRD, BET and FT-IR. The chemical quality of crude sample and its Acid orange 7 was determined and then the influence of pH, absorbent amount and time on the removal of Acid orange 7 was evaluated. The highest percentage of Acid orange 7 absorption was observed at pH=4 , Retention time of 60 Minutes, absorbent amount of 10g/L for synthetic solution with removal efficiency of 82% and for synthetic solution with the eff iciency of 78%. The findings revealed that the removal of Acid orange 7 followed the freundlich isotherm (R2=99%) and the second o rder synthetic model (R2=98%).Nanoporous Materials ( NH2- MCM-41) had a remarkable effect on the removal of Acid orange 7 , so it could be used as an efficient method in removal of Acid orange 7 from industrial effluents.
