| Abstract: | To determine trace copper in water samples such as tap and rain water, neutron activation analysis preceded by chemical preconcentration was developed, in which copper was concentrated by adsorption on activated carbon powder using 8-quinlinol as an adjunct. Short-lived66Cu and long-lived64Cu were used as analytical radionuclides. It was demonstrated that copper can thus be detemined at a μg l−1 (ppb) level. |
