Abstract: In basic condition,mesoporous sieve Sr-MCM-41 is synthesized successfully through mixing cetyltrimethylammonium bromide (CTAB) as a template with strontium nitrate(Sr(NO3)2) as the inorganic source and ethyl silicate as the silica source by hydrothermal synthesis.The products are characterized by XRD and SEM techniques and the adsorption abilities are studied by the adsorption of dyes of methylviolet and fuchsine.The results indicate that the products display the diffraction peak in the low-range angle,the evidence of the mesoporous structure.And the most of the products are of sponge state that is short of the long-range ordered crystal structure.The adsorption of the dyes of methylviolet and fuchsine is in accordance to Freundilich isothermal equation.The biggest adsorption amount of methylviolet is 186mg/g and of fuchsine is 172mg/g respectively.
