In this study, an amine rich functionalized mesoporous silica (Ar@MCM) was synthesized and considered as an adsorbent to remove alizarin yellow and phenol red from wastewater samples. The structure and morphology of the modified nanofiller Ar@MCM were identified by infrared spectroscopy (FTIR), X-ray diffraction (XRD) and transmission electron microscopy (TEM) analysis. Central composite design (CCD) and response surface methodology (RSM) were applied to optimize conditions (amount of adsorbent, pH solution, and temperature). The adsorption behaviors of dyes were studied by isotherm models and equilibrium results were fitted well with the Langmuir isotherm model. The maximum adsorption capacity of the Ar@MCM was obtained to be 370.70 mg g(-1) for phenol red (R-2 = 0.9987) and 400 mg g(-1) for alizarin yellow (R-2 = 0.9990). Finally, the ability of adsorbent was compared with some types of anionic and cationic dyes.
