Resinas poliméricas para separação e pré-concentração de chumbo

This article gives an overview of polymer materials used for lead separation and preconcentration. Different kinds of polymer resins, commercial or not, are cited as well as the most used functional groups attached to polymer backbones. The synthesis of these resins and conditions of lead adsorption and elution are remarked. The influence of the porous structure of the polymer on the resines performance is described as well as the use of spacer arms.
