A non-boiling evaporation method has been studied for the preconcentration of trace metals in highly purified water. A sample (50100 cm3) was taken to a polycarbonate Erlenmeyer flask (250 cm3), and then placed into a water-ethylene glycol (1:1) bath (120°C). While the temperature of the sample was maintained at about 95°C, the vapor in the flask was led to a receiver in an ice bath by passing through air circulated with an air pump for condensation. About 2 hours were required for evaporation to dryness of a 100 cm3 sample solution. After evaporation, 0.5 g of water or HNO3 (0.3 M) was added to dissolve the residue. The metals in the solution were then analyzed by a flameless AAS. Sodium, potassium, magnesium and zinc in highly purified water were found to be determined at a level of 12 ng/dm3 by the proposed method.
