“…Zirconium was one of the elements used in two different studies of the chemical reactions which take place during excitation (493, 513). Isotope dilution and separation by a method employing an anion exchange resin was used along with a surface ionization type mass spectrometer for the determination of hafnium in Zircaloy (625). Zirconium and hafnium were included in a summary of the effects of interfering elements in X-ray fluorescence analysis (314).…”

This review, as did the previous three reviews in this series, attempts to cover a cross section of the methods for the determination of zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, and tungsten. Procedures using all of the more common techniques are mentioned along Element Zirconium Vanadium Niobium Chromium Tungsten Table V. Electrometric Methods Method: Reagent: Material (References)Amperometric: EDTA: Th, Fe, In, Cu, Zn, Pb, Ni, Mg (304); Ni (702) Polarographic: study of conditions (414) Amperometric: Fe(II): study of accuracy (511); Fe, Cr (602); V salts (603)

“…Although there are many methods for dotermining traces of hafnium in zirconium and Zircaloy, neutron activation analysis (1)(2)(3)(4)(5) and isotope dilution mass spectrometry (6)(7)(8) are most often used. The former has high sensitivity, and the latter has high precision and accuracy.…”

“…Accurate determination of traces of hafnium in zirconium and Zircaloy, which are used as cladding material in nuclear reactors, is very important because of its large thermal neutron cross section. Although there are many methods for determining traces of hafnium in zirconium and Zircaloy, neutron activation analysis (1)(2)(3)(4)(5) and isotope dilution mass spectrometry (6)(7)(8) are most often used. The former has high sensitivity, and the latter has high precision and accuracy.…”

2059that generation of 2p core holes occws by processes other than emission of the ESCA '2p electrons. This could depend on other fadors not related to the chemical state of the compound like the state of subdivision of the sample. Thus, the CU 2pfAuger ratio would be of dubious value though the LMVfLVV ratio should be unaffected. Finally, no complications arise in the Auger spectra because of the use of nonmonochromatic X radiation. Registry No.
