Analytical properties of 1-(2-pyridylazo)-2-naphthol immobilized on a polymethacrylate matrix

The adsorption of 1-(2-pyridylazo)-2-naphthol (PAN) with a polymethacrylate matrix from a water-ethanol solution is studied. It is shown that PAN immobilized on a polymethacrylate matrix retains its analytical properties.
