英文摘要	The sorption of Ni(II) on a calcareous aridisol (CA) soil, one of the major soil types in northwestern China, was investigated using batch and extended X-ray absorption fine structure (EXAFS) approaches in a 0.01 mol/L NaClO4 solution at different pH values (6.0-10.0), temperatures (25-60 degrees C) and contact times (2-15 days). Under alkaline conditions, EXAFS analysis showed that the interatomic distances between Ni and O atoms (RNi-O) were approximately 2.04 angstrom with a typical coordination number (CN) of similar to 6.0 O atoms in the contact time range from 2 to 15 days. The RNi-Ni (similar to 3.07 angstrom) suggested that the structure of the Ni(II) adsorbed on the CA soil was basically the same as that of Ni(OH)(2)(s), while the Ni-Al shell (RNi-Al similar to 3.16 angstrom) gradually formed and grew with the increasing contact time. Under weakly acidic conditions, the sorption mechanism of Ni(II) on the CA soil possibly included at least two processes: (i) a fast accumulation dominated by ion exchange and surface complexation and (ii) the formation of a Ni-Al LDH phase over the long term. A high temperature is beneficial to the fixation of Ni(II) on the CA soil and the formation of a Ni-Al LDH.
