    Analytical chemistry in atomic energy
    (Melbourne University Press on behalf of The Australian Atomic Energy Commission, 1958-06-02) Smythe, LE
    The requirements for analytical chemistry in atomic energy are outlined and the impact of increasing instrumentation is discussed. Some recent developments in analytical chemistry instrumentation are reviewed and their possibilities and uses in the atomic energy field are assessed. These include automatic coulometry, square wave polarography, gamma spectrometry, low background beta counting, infra-red spectrometry, mass spectrometry, emission spectrography, X-ray spectrography and vacuum fusion analysis.

    Heavy water reactor chemistry studies. Part 2. the analysis of exhausted HIFAR ion-exchange resins
    (Australian Atomic Energy Commission., 1968-01) Ryan, HF; Smythe, LE
    Four batches of exhausted HIFAR ion-exchange resins have been analysed to obtain information on the nature of impurities in the system, corrosion and radiation degradation of the resins. The life of the ion exchanger was found to be governed by the carbon dioxide in the circuit, the major source of which was the the radiation degradation of the resins. Methods for prolonging the life of the HIFAR ion exchanger were considered.

    Heavy water reactor chemistry studies. Part 3 - role of carbon dioxide
    (Australian Atomic Energy Commission, 1967-10) Ryan, HF; Smythe, LE
    The mechanism of the absorption of bicarbonate ions onto both unirradiated and irradiated Amberlite XE-78 resin in the OH form was studied using a C14-tracer techniques. The data obtained from these laboratory experiments have been related to reactor conditions in HIFAR. The mechanism of absorption of dissolved carbon dioxide and other anionic impurities from the HIFAR moderator onto the anion exchange resin is now understood.
