Sorption and Desorption of Phenanthrene by Organo-mineral Complexes with Different Bridge Cations
|
Abstract:
Sorption and desorption of phenanthrene by organo-mineral complexes with Ca~(2+),Fe~(3+) and Al~(3+) as bridge cations were studied according to the association type between organic matter and minerals in natural soils.The results showed that the data of phenanthrene sorption and desorption by different cation saturated montmorillonite and their corresponding humic acid and mineral complexes could be fitted with Freundlich model,and the order of the sorption capacities(K_f) were Ca-Mont(0.184)> Fe-Mont(0.02...
