Preparation, characterization, and metal-sorption studies of a mordant yellow 10-loaded wool, a new stable chelating material based on bleached wool

Vladescu L., Costache M., Badea I.

Acta Chromatographica

2004

No. 14

187-197

A new stable chelating material has been prepared by loading blea-ched wool with mordant yellow 10. The sorption capacity of the bleached wool for the organic reagent and the stability of the new material in acidic solutions were established. The sorption capacity of the new material for Fe3+, the effect of pH on adsorption of Fe3+, and conditions for the removal of Fe3+ were established. The new material has been tested for separation and concentration of Fe3+ at trace levels in synthetic solutions and natural waters.
