Determination of trace amounts of magnesium, strontium and nickel in lake-water samples by neutron-activation analysis
Abstract
Neutron-activation analysis has been used to determine magnesium, strontium and nickel in water from eleven Greek lakes. The elements were separated by an isolation procedure (taking up to 30 minutes); the magnesium and strontium were determined by γ-spectrometry, and the nickel by β-co-incidence counting. The ranges found were 11 to 31 p.p.m. of magnesium, 0·02 to 1·12 p.p.m. of nickel and 0·07 to 0·48 p.p.m. of strontium.
