The poly(acrylic acid) hydrogel (PAA) has been suggested as adsorbent
material to treat cobalt-60 in radioactive liquid waste. The kinetics of
isothermal adsorption of cobalt ions from an aqueous solution onto PAA
hydrogel was investigated in the temperature range from 298K to 315 K.
The kinetic model of Co2+ adsorption [1-(1-α)1/3]2=kt, was established by
using the model-fitting method. The kinetic parameters of Co2+ adsorption
(Ea = 41 kJ mol-1, ln [A/min-1]=12) were determined. It was found that
cobalt adsorption was kinetically controlled process which is determined by
the rate of three-dimensional diffusion Co2+ ions (D3).
