摘要：

The conversion of 3-AT-R cheating resin was optimized by response surface method and effects of different reaction conditions were studied. Moreover, mercury adsorption and desorption properties of the 3-AT-R resin were investigated, and factors including pH, ions and temperature on mercury adsorption were studied via FTIR and TGA. The results show that the maximum saturated adsorption capacity is 382.5 mg∙g -1 under pH = 6.0 and 308 K. The adsorption kinetic and equilibrium data were well fitted with the pseudo-second-order model. Desorption studies reveal that mercury ion can be effectively eluted using 2 mol∙L -1 HCl and the desorption efficiency is 100%. These results show that the 3-AT-R chelating resin have advantages of high selectivity, adsorption and elution efficiency for mercury ion. © 2018, Editorial Board of Journal of Chemical Engineering of Chinese Universities".
