摘要：

Satisfactory sorption capacity towards heavy metals of several physically modified chelating resins at low pH is reported. It was found that the linear sorption isotherms are the most appropriate for describing the sorption of Ni and Pb. The data obtained revealed that the chelating resins studied are able to remove selectively copper from a complex synthetic solution containing Fe, Mn and Pb. The regeneration of Lewatit TP 208 by 10% H2SO4 in batch conditions proved to be effective through three consecutive runs of loading-regeneration.
