Original Paper


Cellulose films containing entrapped analytical reagents suitable for metal-ion detection are produced by joint dissolution of cellulose and the reagents in ionic liquids then precipitation with water. The conditions of preparation of these test materials have been optimized and their properties have been studied. The film obtained by use of the ionic liquid 1-butyl-3-methylimidazolium chloride and 1-(2-pyridylazo)-2-naphthol has been used for colorimetric determination of divalent zinc, manganese, and nickel with detection limits at the 10−6 mol L−1 level.

We are much indebted to Professor K. Bogolitsin (Arkhangelsk State Technical University) for providing samples of cellulose and lignin and to Professor V. Ivanov (Lomonosov Moscow State University) for providing some of the analytical reagents. We are also grateful to Professor N. Nikonorova (Lomonosov Moscow State University) and to Professor I. Kubrakova (Vernadsky Institute of Geochemistry and Analytical Chemistry, RAS) for providing electronic scanning microscopy and the microwave oven. Thanks are also due to Russian Foundation for Basic Research for the financial support (Grant no. 05-03-32976).
