文摘
- •
A novel magnetic adsorbent (Na-(CS/PAA)n/MPC) was prepared by LbL method.
- •
This adsorbent exhibits high loading capacity for removal of cationic dyes.
- •
The uptake capacity increases linearly with the number of coated (CS/PAA) bilayer.
- •
The adsorption behavior is endothermic monolayer chemisorptions.
- •
This adsorbent shows excellent reusability and good magnetic separability.
