Abstract

The preparation of nano-structured silica has opened a wide field of applications since 1992 until now. In comparison with other nano-structured silica materials, SBA-15 exhibits thicker pore wall, higher pore volumes, and wider pores. The silica wall surface of nanoporous silica can be modified with organic groups to tailor their properties and achieve specific purposes. Among the main uses of nanoporous silica, it is well-known the design of adsorbents for environmental clean up and many reports can be found. Removal of dyes from aqueous solutions is one of the major problems in wastewater treatment, since they are mostly toxic. MALACHITE GREEN, a triphenylmethane dye, has been widely used for the dyeing of leather, wool, and silk as well as used as a fungicide and antiseptic in aquaculture industry to control fish parasites and disease. But recently, MG has been found exhibiting carcinogenic, genotoxic, mutagenic, and teratogenic properties, and so the use of MG by the FDA is forbiddened, In this study MG removed from waste water by using this carboxylic functionalized SBA-15 and the isotherm diagrams and its kinetic were studied. BET ADSORPTION/desorption isotherm showed 603, 277, and 252 m2g-1 surface area for SBA-15, SBA-15-NH2, and SBA-15-COOH, respectively. Reduced surface area was related to step by step MESOPOROUS functionalization. Isotherm study was done. Isotherm data obeyed the Freundlich model so that multi-layer ADSORPTION of MG on SBA-15-COOH was expected. In comparison with two other adsorbent SBA-15-COOH led to a better result. SBA-15-COOH kinetics data for ADSORPTION model obey semi-first order model.
