|Title:||Methylene Blue Immobilized In Cellulose/tio 2 And Sio 2/tio 2: Electrochemical Properties And Factorial Design [azul De Metileno Imobilizado Na Celulose/tio 2 E Sio 2/tio 2: Propriedades Eletroquímicas E Planejamento Fatorial]|
|Abstract:||The electrochemical properties of methylene blue immobilized on cellulose/TiO 2 and mixed oxide SiO 2/TiO 2 matrices were investigated by means of cyclic voltammetry. The electron mediator property of the methylene blue was optimized using a factorial design, consisting of four factors in two levels. The experimental observations and data analyses on the system indicate that the lowest peak separation occurs for Sil/TiOAM, 1.0 mol L -1 KCl solution and 20 mV s -1 scan rate, while values of current ratio closest to unity were found for Cel/TiOAM independent of electrolyte concentration. 0.2 or 1.0 mol L -1, and scan rate, 20 mV s -1 or 60 mV s -1.|
