Use of Ligands for Improved Separation of Metal Ions on Thin Silica Layers

摘要

2,2#x2032; dipyridyl and iminodiacetic acid have been employed as impregnants for improving the separation of thirteen metal ions of interest using the solvent system Isoamyl alcohol-H2O-AcOH (20:10:10) and MeOH-Benzene-AcOH (20:10:15). Metal ions have been divided into two groups as toxic metal ions and metal ions in vivo for a satisfactory separation.
