Abstract :
The present work reports on simple and effective ecofriendly approach for the valorization of waste of the wood industry in the environmental application as adsorbent biomaterials. The biomaterial was characterized using various instrumental techniques including scanning electron microscope coupled at energy dispersive spectroscopy (SEM/EDS) and Fourier transformed infrared spectroscopy (FTIR). In the other hand, other study is about optimization of sorption of Methylene Blue dye (MB) from aqueous solution onto the biomaterial prepared from waste of the wood industry using Response Surface Methodology (RSM). Effect of process parameters such as dosage of biomaterial, initial dye concentration, stirring speed, size of grains of adsorbent, and their interaction on the sorption were studied by using full factorial Central Composite Design (CCD).
