Afzal, Javed Hanif, Imtiaz Hanif, Riaz Qadeer, M. Saleem] The samples were introduced into the XRF spectrometer in ordinary flat bottom polyethylene bottles for the estimation of Zr or Hf in presence of one another in solution. By using high voltage (50 kV) and high current (50 mA) least limits of detection obtained were an order of magnitude better than other conventional analytical techniques. Relations of intensity to concentration in various concentration ranges have been determined and the results are compared with those of other analytical techniques. Akadémiai Kiadó, 1990 Afzal M.
