چکیده: Polystyrene resin was functionalized by diethanolamine for the efficient removal of p-toluenesulfonic
acid (p-TSA) from aqueous solution. Functionalized adsorbent (DEA-PS) was characterized by elemental
analysis, Fourier transform infrared spectroscopy, point of zero charge measurement and field-emission
scanning electron microscopy. According to the results, maximum removal of p-TSA was observed at the
pH range of 2.5–5. The adsorption kinetics of p-TSA onto DEA-PS was represented by pseudo-first-order
model and the equilibrium data followed Langmuir model well. The adsorption process was
endothermic and spontaneous, along with the positive change of entropy. The regeneration of DEAPS
was also conducted by 1 M NaOH solution.
