Twenty five impurity elements in aluminium applied as reactor material are determined. Titanium and nickel are determined with epithermal neutron activation analysis (NAA), magnesium and silicon by inductance coupling plasma emission spectra (ICP), other elements by thermal NAA. The fission coefficient of uranium is given by an experiment, the interferences of uranium to Ce, Nd, Mo, Zr, La, Sm are subtracted. The detection limits of these methods to all of impurity elements in aluminium are calculated.
