文摘

A total reflection X-ray fluorescence method was developed to ascertain the absence of indium at a concentration level of >1 ng/mL in heavy water samples. A continuum strip in the energy range of 25-5 keV was used for sample excitation and In Kub>αub> was used as analytical line. The detection limit for indium, obtained after preconcentration and continuum excitation, was found to be 1 ng/mL with a sample size of 2 μL. A heavy water sample was analysed for indium using this approach. Keywords Heavy water Reactors Coolant Moderator TXRF
