Removal of Organic Dyes by Using Cellulose-Chitosan-Nanowires Hybrid Composition Beads

Abstract

Organic dyes are mostly used in textile, paper, plastic, and other industries. These industries can be toxic and harmful to environment and human. Adsorption is the most efficient method to control wastewater that contains dyes. Cellulose-Chitosan beads was mainly used in the adsorption. To increase and enhance the organic dyes removal capacity of these beads, titanium dioxide nanowires (TiO2Nw) as used to achieve novel Cs-Cell-nanowires hybrid composites. Ultralong hydroxyapatite nanowires was prepared and used to enhance the mechanical and thermal properties of beads. On the other hand, the beads composition was prepared with spherical white shape. Internal structure of beads and other composition were studied by using Attenuated Total Reflectance (ATR) spectroscopy, scanning electron microscopy (SEM), lazer diffraction (LD), thermal analysis (TG, DSC, DTG, and DTA). The beads are tested with five different organic dyes which include Methyl blue (MB), Acid alizarin Black (AAB) as cationic dyes, and Methyl orang (MO), Methyl red (MR) and Eriochrome black T (EBT) as anionic dyes. The results indicate that the beads have the ability to remove MB, EBT,AAB but do not have the ability to remove MO and MR. So, the Cell-CS- HAPNw- TiO2Nw beads can be considered as the promising adsorption for MB, EBT, and AAB from aqueous solutions.
