Determination of aluminium by instrumental neutron activation analysis in biological samples with special reference to NBS SRM 1577 bovine liver.

It was found that a well thermalized heavy water-moderated research reactor can be used to determine the Al content of biological samples without separation of P, Na and Cl. The contribution of the 31P(n,alpha)28Al reaction was corrected from the known concentration of P and the measured effective value. It was found that the contribution is only about 10%. A method is suggested for the determination of Al using instrumental neutron activation analysis.
