✦ Synopsis

The chelating ion-exchanger Cellex-P, a cellulose phosphate ester, is shown to he effective for the preconcentration of Cu, Ni, Mn, Cd, Zn and Pb from water. The pH of the sample is not critical within the approximate range 5-8. The collected ions can he eluted efficiently in lo-25 ml of 1 M nitric acid from 2-16.5-cm columns of resin. Common salts present in natural waters do not interfere. Cellex-P is used for the preeoncentration and determination of the metal ions in potable water by graphite-furnace atomic absorption spectrometry.
