In this work, porous chitosan (CS) was investigated as a biosorbent for the removal of iron (II) from the synthetic fracking wastewater. The underlying problem with the production water from fracking industries is that it contains iron (II) up to 55 mg/L, which needs to be eliminated. Porous CS had a specific surface area of 1.05 m 2 /g with the average pore diameter of 319 A, as determined by using Brunauer-Emmett-Teller surface area analysis. The kinetics, isotherms, and thermodynamic analysis confirm that the porous CS can be a potential candidate for iron (II) removal.Both the pseudo-first-order model and pseudo-second-order model have good fit on iron (II) adsorption with the porous CS. Kinetic studies revealed that the CS-iron (II) adsorption system was controlled by intraparticle diffusion. The monolayer adsorption capacity of the porous CS from Langmuir model was found to be 51.81 mg/g. The experimental data were fitted against common adsorption isotherms and yielded excellent fits in the following order:Langmuir > Temkin > Freundlich > Dubinin-Radushkevich isotherms. Thermodynamic studies revealed that the adsorption of iron (II) onto porous CS was feasible and spontaneous. The adsorption process is endothermic, and the entropy is the driving force.
