摘要: Abstract The effect of cationic template on the adsorption chromium (VI), furfural and copperphthalocyanine-3,4′,4″,4‴-tetrasulfonic acid tetrasodium salt (CuPc) in MCM-41 MCM-48 mesoporous materials was investigated this work. We used cetyltrimethylammonium bromide (CTAB) as sodiummetasilicate (for MCM-41) tetraethyl-orthosilicon MCM-48) silica source for synthesis materials. properties synthesized samples were characterized with XRD-low angle, SEM, N 2 adsorption–desorption TG–DT analysis. extent a function solution pH, shaking speed, contact time, analyte concentration, reaction temperature supporting electrolyte (sodium chloride) concentration. Langmuir Freundlich isotherms to model equilibrium data. as-synthesized showed very high capacity analytes uptakes rapid adsorbents reaching less than 2 h. without surfactant did not show significant affinity analytes.
