Adsorption and Photocatalyst of Methylene Blue on Mesoporous Bioactive Glass with La and Ti Dopants

The present study demonstrates a series of environmentally friendly lanthanum and titanium doped mesoporous bioactive glass with adsorption, photocatalytic and regeneration performance for methylene blue via the sol-gel method. The materials were studied by XRD, XPS, TEM and BET. The influence of the initial dye concentration, contact time, solution pH, temperature, photocatalytic performance and regeneration performance of this glass adsorbed methylene blue were investigated. It is shown that the Freundlich and Langmuir adsorption isotherms can be used to study the equilibrium of methylene blue removal process by bioactive glass. Another test on photocatalytic degradation performance and reproduction performance of the materials by removing methylene blue. This article has its potential in treatment of dyeing waste water as it improves structure and performance by adding La and Ti to mesoporous bioactive glass.
