Abstract :
The modified mesoporous silica with aminopropyl group (NH2-(CH2)3-MCM-41) and chloropropyl group (SH- (CH2)3-MCM-41) and pure mesoporous silica (MCM-41) have been synthesized via the microwave-assisted hydrothermal method. The samples were characterized by X ray diffraction, FT-IR spectroscopy and Nitrogen adsorption-desorption. Then adsorption test of copper ion was investigated. Langmuir model is favorable to describe the adsorption kinetics. Results indicate that maximum adsorption amounts of the modified silica and pure silica are 25.64mg/g, 27.47mg/g and 16.58mg/g, respectively. Furthermore, the samples can be utilized for enrichment the trace metal, which was testified by preconcentration of Cu(II) experiment.
