中文摘要	利用热力学吸附平衡法研究了干旱区绿洲灌漠土和灰钙土Cu,Ni的吸附解吸行为.结果表明:Henry方程,Freundlich方程可以较好地模拟Cu,Ni在灌漠土和灰钙土中的等温吸附特征;灌漠土和灰钙土对Cu,Ni吸附选择顺序都为Cu>Ni,灰钙土Cu,Ni之间的竞争作用大于灌漠土中的;灌漠土和灰钙土Cu的解吸率都远远小于Ni的,两种土壤Cu的吸附滞后作用都比Ni的强.
英文摘要	Laboratory batch experiments were carried out to study the sorption and desorption of Cu and Ni in the irrigated desert soil and gray calcareous soil from the oasis in the arid regions of northwest China. The results show that, under the coexistence of Cu and Ni, adsorption of Cu and Ni in the irrigated desert soil and the gray calcareous soil is well described by both Henry and Preundlich equations; the selectivity sequence of Cu and Ni sorption in irrigated desert soil and gray calcareous soil is Cu>Ni, and the competitive interaction between Cu and Ni in gray calcareous soil is more significant than that in irrigated desert soil; percentage of Cu and Ni desorption in irrigated desert soil and gray calcareous soil is Cu>Ni, and sorption hysteresis of Cu and Ni in both soils is also Cu>Ni.
