Notice of Retraction Dye Decolorization and Dissolved Oxygen Properties of Sodium Alginate/Carbon Nanotubes Microsphere

In an effort to produce more environmentally friendly materials, renewable and biodegradable biopolymers have been investigated as coating materials. A sodium alginate (SA) and multi-wall carbon nanotube (MWNTs), one of the SA, has been used for the removal of harmful dyes (anionic dye methyl orange (MO)) from contaminated water via adsorption. Adsorption of MO onto SA/MWNTs was investigated with respect to decolorization, pH, dissolved oxygen, electrical conductivity. This characteristic makes hydrogels of SA/MWNTs attractive for potential uses in biomaterial and dyestuff treatment applications.
