Abstract
The authors have prepared colloidal dispersions of polypyrrole-poly(vi nylalcohol) composites doping carbobenzoxy-L-aspartic acid, using the oxidative polymerization technique. The colloid was used to resolve th e enantiomers of glutamic acid (glu) and valine (val). When 15 mg dm(- 3) colloid was added to a solution containing 1.0 x 10(-4) mol dm(-3) D-glu or L-glu and 2.0 x 10(-4) mol dm(-3) cupric ion, about 50% and 1 0% of D- and L-glu were extracted into the colloid, respectively.
