چکیده انگلیسی
Our results demonstrate that magnesium–aluminum oxide (Mg–Al oxide) can be advantageous in treating hydrochloric acid waste at temperatures between 10 and 30 °C, by acting as both a neutralizer and fixative for Cl−. The Mg–Al oxide was prepared by the thermal decomposition of a hydrotalcite-like compound. The extent of Cl− removal by Mg–Al oxide increased with increases of temperature, oxide quantity and Mg/Al molar ratio. The initial pH had little effect on Cl− removal; the pH increased rapidly from the start of the reaction and attained a nearly constant value. The reaction involved in Cl− removal from HCl by Mg–Al oxide proceeded under surface chemical reaction control, with apparent activation energy of 65.6 kJ mol−1.
