Removal of Copper-phthalocyanine from Aqueous Solution by Cationically Templated MCM-41 and MCM-48 Nanoporous Adsorbents

摘要

The effect of cationic template on the adsorption of copper-phthalocyanine-3,4,4,4-tetrasulfonic acid tetrasodium salt [Cu(tsPc)-4·4Na+] in MCM-41 and MCM-48 mesoporous materials was investigated, using cetyltrimethylammonium bromide (CTAB) as the cationic template and tetraethyl-orthosilicate as the silica source for synthesis of mesoporous materials. The properties of synthesized samples were characterized with XRD-low angle and scanning electron microscopy. The as-synthesized mesoporous samples were used for the separation of Cu(tsPc)-4·4Na+ from aqueous solution, which showed very high adsorption capacity for it.
