Abstract
In this work, a biohybrid material based on SiO2-alginate was obtained and its properties of adsorption evaluated using methylene blue as a model dye. The experimental results showed that the biohybrid SiO 2-alginate has a higher adsorption ability compared to their base compounds (SiO2 and alginate). Methylene blue adsorption is pH dependent, resulting in a maximum adsorption at pH 8. The sorption kinetics rate is similar to SiO2. Kinetic data were fitted to a model of pseudosecond order. The experimental isotherms fit well the Langmuir model. © Published under licence by IOP Publishing Ltd.
