Surfactants and Colloids in the Environment presents the proceedings of the General Meeting of the German Colloid Society (Kolloid-Gesellschaft) held at the Research Center of Jülich (KFA), FRG, in 1993.The volume emphasizes the importance of colloid chemistry in environmental research. Contributions on the physico-chemical behavior of colloids and surfaces in environmental technology demonstrate the high standard and usefulness of colloid science in this field: General colloid and environmental science complement each other. Thus, the detailed contributions in this volume will be useful toward solving some environmental problems.
