- •
Chitosan beads modified with multi wall carbon nanotubes were prepared and used for DB71 adsorption.
- •
The morphological of nanocomposite was characterized by scanning electron microscopy (SEM), Fourier transfer infrared spectroscopy (FT-IR) and thermogravimetric analysis (TGA).
- •
Optimization based on the CCD has investigated for DB71 adsorption process on ch- MWCNTs.
- •
Various kinetic models and isotherms were evaluated to describe the adsorption process.
