The present invention relates to the field of lining materials which are used to isolate landfill sites in order to avoid pollution of surrounding soil by ions such as heavy metals. In essence, the present invention discloses a process to increase the ion adsorption capacity of clay or dredged sediment. More specifically, the present invention discloses a process comprising: a) mixing said clay or dredged sediment with an anionic polymer, and b) subsequently drying said mixture, results in a lining material having superior ion adsorption characteristics. |
