| Abstract: | A method of chelate resin column on-line enrichment combined with flame atomic absorption spectrometry (AAS) for the determination of Cu and Zn in natural water was reported. Conditions for enrichment, influence of interferences and availability of the method were studied in detail. An enrichment factor of two orders of magnitude can be reached. Sensitivity of the method was comparable to the graphite furnance AAS and accuracy of the determination was improved. |
