Abstract:

The impact of particle size on biosorbent performance is not well researched. Batch tests found pine and hardwood (HW) had a chlorophenol (CP) uptake of 3.1-7.1 mg g-1 with an initial rapid uptake but equilibrium within 72 h. Pine particle size (0.6-4.75 mm) was relatively independent of surface area and equilibrium CP uptake. This was due to the elongate nature of the ground particles which had a length to width ratio of between 4:1 and 8:1 and a sieved particle size closely aligned with particle width rather than particle length. Intra-particle diffusion was a dominant sorption mechanism. Sorption-desorption isotherms of CP on pine and HW can be best described by the Freundlich equation. Desorption of CP showed greater hysteresis with increased hydrophobicity. © 2014 © 2014 Taylor & Francis.
