Abstract  

Preliminary enrichment by means of strong acid ion-exchanger foils has been used to determine trace amounts of metals in water. The kinetics of the exchange reaction between the hydrogen ions in the cation-exchanger foil and metal ions in the solution has been studied. The time needed for the attainment of equilibrium and the values of the distribution coefficients have been determined for Fe2+, Zn2+, Pb2+, Ca2+, Cd2+ and Ba2+ ions. The metal contents in the cation-exchanger foil were determined by means of non-dispersive X-ray fluorescence. The feasibility of the method was determined on the examples of Pb, Zn and Cd ions. The method permits trace amounts of these elements to be determined above 0.01 ppm in the solution. No significant matrix effect due to the presence of Ca and Ba was found for concentration in the solution below 60 ppm.
