A mono-6-thio-I super(2)-cyclodextrin-modified silver film was synthesized via galvanic displacement on copper foil. The prepared silver films could enrich non-polar polychlorinated biphenyls (PCBs) molecules from hydrophilic phase using thiolate I super(2)-cyclodextrins (SH-I super(2)-CDs) as recep...
