Abstract:Prepared a larger aperture mesoporous silica materials by means of one step synthesis, analyzed the sample’s structure and performance through transmission electron microscope, and compared the copper ion adsorption between aminated silica and ordinary silica. The experimental results show that: mesoporous silica particle diameter is about 100 nm, mesoporous is controlled in 10 nm and mesoporous arranges orderly and regularly; the copper ion adsorption rate of mesoporous materials is twice as much as that of ordinary Nano silica.
