Adsorption of methylene blue dyes in aqueous medium by polylactic acid/olive husk flours biocomposites

Abstract

The dyes present in the waste from the textile industry represent a real danger for humans and their environment, due to their low biodegradability and their toxicity. For this, new eco-designed technologies for the treatment of polluted water. Several materials have been used in photocatalysis.
This work aims to degrade the dye Methylene Blue (BM) by photo catalysis-solar using polylactic acid /Olive husk flours biocomposites materials.
The degradation of this substance was followed by UV/Visible spectrophotometry, and the best result was obtained by the composite material loaded with 30% olive husk
