5. Conclusions
The present work shows that JFP can be used as an adsorbent
for the removal of methylene blue dye from aqueous solutions. The
amount of dye adsorbed was found to vary with initial methylene
blue concentration and contact time. The type 2 Langmuir
adsorption isotherms was found to provide the best fit to the experimental
data with maximum adsorption capacity of 285.713 mg/g.
The adsorption kinetics can be predicted by pseudo-second-order
kinetic. The results of the present investigation indicate that the JFP
has a potential for use in removing methylene blue from aqueous
solutions.
