文摘
- •
Linseed deoiled-cake activated carbon efficiently removes AO and AzB from water.
- •
Freundlich model correlates isotherm data, suggesting heterogeneous sorption sites.
- •
Exhibits higher Langmuir saturation capacity of 213.57 (AO) and 136.58 (AzB) mg/g.
- •
The kinetic data best agreed with pseudo-second-order kinetic model.
- •
Adsorption is controlled by diffusion in the liquid-film surrounding the adsorbent.
