摘要：

A sample preparation procedure based on the interaction of the colloidal particles with a polymeric substrate is developed. An active retention process of silver colloid is described by means of electrostatic interactions between the colloidal micelles and the active sites of an anion exchange polymer. This produces extraordinarily improved chemical and long-time stability of the substrate.
