摘要：
The solidification/stabilization of sodium arsenite, sodium arsenate, arsenic trioxide and arsenic pentoxide at dosages of approximately 10% has been investigated using sequential batch leaching tests. The leaching of arsenic, which was found to be diffusion based, was clearly least effective for those formulations containing additional iron(II). Calcium was found to influence the leaching of cement immobilized arsenic: those formulations containing the greatest Ca:As mole ratios were generally the most successful. Analysis using both FTIR and SEM revealed substantial changes to the cement matrices of those formulations to which the ferrous sulfate had been added. Ettringite was identified in the cement + ferrous sulfate formulations. (C) 2003 Elsevier Science Ltd. All rights reserved.
