Summary

Preconcentration of Trace Elements on Oxine Cellulose

8-Hydroxychinoline, covalently bound to filter cellulose (oxine cellulose), was used for preconcentrating trace metal ions from complex matrices and for matrix separation, respectively. Mn, Fe, Co, Ni, Cu, Zn and Cd traces were preconcentrated on columns filled with oxine cellulose and analysed by AAS and ICP after being eluted with dilute HNO3. At a given pH-value, alkali and alkaline earth metal ions can be quantitatively separated as matrix elements; high concentration factors are obtained and the eluates can be measured without interference. The usefulness of the method is shown by control analyses of EPA- and NBS-SRM's.
