Abstract�� The kinetics of the sorption of NTS onto H1020 macroporous adsorption resin in aqueous solution was investigated in batch experiments at 298 K.The experiments showed that low pH was benefit to sorption and the pseudo second-order equation could describe the sorption process well.Film diffusion was the key step in this adsoption system.The diffusion coefficient(D) was calculated by using Fick's equation from the first portions of the sorption/desorption curves D=0.64��10~(-9) cm~2/s.
