Continuous production of high‐purity water by electro‐deionisationWiley - Tập 21 Số 4 - Trang 117-120 - 1971
Zdeněk Matějka
AbstractOperating conditions were investigated for a packed‐bed membrane cell for electro‐deionisation of brackish or tap water to give high‐purity water with electrical conductivity of the order 0.1 μmho/cm. Flow rates of 10–40 h−1, current densities of 0.5–5 mA/cm2, and incoming solution concentrations of up to 0.01 N wer...... hiện toàn bộ
The preparation and characterisation of crystalline α‐zirconium phosphateWiley - Tập 23 Số 3 - Trang 215-224 - 1973
Stuart E. Horsley, D.V. Nowell
AbstractCrystalline α‐zirconium phosphate has been prepared by four methods. The products have been characterised by chemical and thermal analysis, X‐ray and infrared spectroscopy, surface area, porosity and particle size determinations and electron microscopy. A method is recommended for the preparation of crystalline α‐zirconium phosphate.
The reversibility of the reaction CaCO3 ⇄ CaO+CO2Wiley - Tập 23 Số 10 - Trang 733-742 - 1973
Ronald Barker
AbstractThe reversibility of the reaction CaCO3 ⇌ CaO+CO2 has been examined through a large number of cycles (up to 40), mainly at 866 °C. The decomposition to the oxide is always 100% but the reactivity of the oxide so formed to carbon dioxide falls off markedly after a rapid initial reaction. There is a large increase in ...... hiện toàn bộ
Hydrolysis of pentosans in bagasse pithWiley - Tập 26 Số 5 - Trang 283-287 - 1976
Charles I. Nee, Wen F. Yee
AbstractWork has been conducted on the hydrolysis of pentosans in bagasse pith as the first part of a study of the chemistry of bagasse processing aimed at establishing an integrated industry. Bagasse pith is the fine part screened out and discarded as waste during the preparation of raw material for bagasse pulping plant. By using dilute sulphuric acid at a concen...... hiện toàn bộ
