摘要/Abstract

摘要： 通过实验室模拟, 研究氟铝交互作用对茶园土壤中铝的吸附特征和形态分布的影响. 结果表明, 在氟铝交互作用下, 茶园土壤中铝的吸附平衡时间延长, 吸附速率下降, 吸附量减少. 茶园土壤对铝的吸附速率和吸附量大小顺序为：对照>n(F)∶n(Al)=2>n(F)∶n(Al)=4>n(F)∶n(Al)=8；对照和低氟铝比（n(F)∶n(Al)=2∶1）条件下, 随茶园土壤对铝吸附量的增大, 活性铝含量增加但转化率下降；高氟铝比（n(F)∶n(Al)=4∶8 ∶1）条件下, 随茶园土壤对铝吸附量的增大, 活性铝含量下降且转化率进一步降低.

Abstract: Effects of interaction of fluoridealuminum on adsorption characteristics and distribution of aluminum in tea garden soil were studied . With the elongation of the sorption time, decreasing in sorption rate and redu cing in sorption capacity for aluminum in the tea garden soil were obtained in the order: control>n(F)∶n(Al)=2>n(F)∶n(Al)=4>n(F)∶n(Al)=8, in the different ratios of fluoride to aluminum. The transformation rate of the active aluminum is lessened with the increase of sorption amount of aluminum in the tea garden soil while the active aluminum quantity increased obviously under the control and n(F) ∶n(Al)=2 ∶1. However, with the increase of the sorption amount of aluminum, the content of active aluminum decreased and the transformation rate of active aluminum further decreased in the presence of n(F)∶n(Al)=4 and n(F)∶n(Al)=8.
