In order to study Cd2 + adsorbing function of NH 3 GMCMG41 in waste water,the authors used one stage synthetic method to prepare mesoporous silica with regulated openGframeG work structure by using coal ash as silicon source,CTAB as template agent,ammonia as catalyst and potassium chloride as additive in room temperature,and then functional modification was carried out with NG(aminoGethyl)GaminoGpropyl trimethoxysilane,and bringing in amido which can adsorb Cd2 + ions?? According to representation of N2 absorbGdesorption,SEM,XRD and FTG IR measurement,amino functional group loaded on silica surface?? The results of absorption test showed that the optimal operating conditions aminoGmodified mesoporous silica absorbed Cd2 + in waste water was 25 min,8 pH value and 1??0 g adsorbent additive quantity.
