Al2o3 Coated With 3-n-propyl-1-azonia-4-azabicyclo[2. 2.2]octane Silsesquioxane Chloride And Its Use For Immobilization Of Cobalt(ii) Tetrasulfonated Phthalocyanine In Oxalic Acid Electrooxidation

Abstract

A water-soluble polymer prepared by sol-gel process, 3-n-propyl-1-azonia-4- azabicyclo[2.2.2]octane silsesquioxane chloride, was adsorbed on alumina surface. This polymer-coated alumina was able to effectively immobilize cobalt(II) tetrasulfonated phthalocyanine complexes as counter ions. Cobalt phthalocyanine immobilized in this way is well and tightly adsorbed on Al 2O3/3-n-propyl-1-azonia-4-azabicyclo[2.2.2]octane silsesquioxane chloride surface. Furthermore, when incorporated to a carbon paste electrode showed a good electrocatalytic response toward the acid oxalic oxidation, making it a suitable electrode material. A linear relationship (r = 0.998) between the current responses obtained by chronoamperometric measurements and the oxalic acid concentration in the range of 7.4 × 10-5 - 9.1 × 10-4 mol L-1 was observed. A detection limit of 18 μmol L-1 was also determined. ©2008 Sociedade Brasileira de Química.194755761Templin, M., Franck, A., Du Chesne, A., Leist, H., Zhang, Y., Ulrich, R., Schädler, V., Wiesner, U., (1997) Science, 278, p. 1795Lee, K., Itharaju, R.R., Puleo, D.A., (2007) Acta Biomaterialia, 3, p. 515Yuan, J., Zhou, S., You, B., Wu, L., (2005) Chem.
