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.
