| Summary: | Nanocellulose, a refined form of cellulose, can be further functionalized on surface-active
sites, with a catalyst as a regenerative agent. Newly developed adsorbents are expected to have the
characteristics of good and rapid adsorption performance and regeneration properties with flexible
structure using 3D printing technology. In this work, the adsorption performance of 3D printed
functionalized nanocellulose was investigated using batch and fixed-bed column adsorption. Kinetics
adsorption studies were divided into different adsorption models, with the pseudo-second order
model showing a better correlation coefficient than the pseudo-first order and intraparticle diffusion
models. The Langmuir and Thomas models were used to calculate the adsorption performance of
batch and fixed-bed columns. Given the catalytic activity of Fenton oxidation, the fixed-bed column
was regenerated up to five adsorption-desorption cycles, suggesting satisfactory performance of the
column, with a slightly reduced adsorption capacity |
