Abstract

Instrumental neutron activation analysis (INAA) was applied to the rapid determination of aluminium in drinking water. Aluminium content was quantitatively determined by measuring the γ-ray photopeak at 1778 keV of the short-lived radionuclide28Al (half-life 2.25 min). The experimental procedure was aimed at reducing significantly all contributions to the background. The aluminium concentration in various sources of drinking water was found to range from 80 to 170 μg·1−1, well within the recommended European Standard of 200 μg·1−1. The limit of detection (LOD), when assaying a sample of 10 ml under the specified experimental conditions, is 100 ng of Al.
