Trace metals in water were preconcentrated with solvent extraction. Then the extracts were reextracted to water in the medium of concentrated nitric acid. The recoveries of the trace metals at concentration of 0.25pg/mL were found to be 90%-96%. The concentration of Cu, Cd, Zn and Pb were determined in river of Büyük Menderes, Sakarya and Kızılırmak At the same time river water were evaporated to dryness and were determined the trace metals concentration.
