The paper describes the combined use of a preconcentration method using a chelating resin [iron(III)-loaded] and ICP-AES for determining As, Mo, V and W simultaneously in polluted waters. The method, suitably modified, can also be used for studying the analytes at natural levels down to μg g-1 in solid environmental matrices. The method has been applied to five geological reference samples (GXR series) kindly supplied by the U.S.G.S. The method, whose reliability has been checked on standard reference materials (NIST), is easy to apply and also characterised by good precision.
