摘要：

This work investigates the ability of EPS extracted by cationic exchange resin (CER) from 3 different anaerobic granular sludges to bind Pb or Cd as a function of pH. EPS display a better binding ability for Pb than Cd as it has been often shown in literature. The experimental sorption data show the presence of a pH sorption edge. The experimental data are well fitted by the Kurbatov model. Nevertheless, the molar ratio of proton exchanged with metal ions underlines that other mechanisms are also involved in metal ion sorption by EPS from anaerobic granular sludges. Moreover, the mineral fraction present in extracted EPS and trapped by the organic fraction or under particle form seems to be involved in the metal ions sorption process.
