Özet:

 

In this study, the adsorption from solution technique was  used for the determination of surface areas of some silicate samples  (bentonite, sepiolite, zeolitic tuff and kaolin).  Methylene blue  (MB), orthophenanthroline (OP) and p-nitrophenol (PNP) were selected  as solutes.    The adsorption data was found to conform with the Langmuir equation   within the concentration range studied, and Langmuir constants were   determined for each of the samples.     The surface area values obtained were compared with those determined   by nitrogen adsorption. Also the results were discussed with respect   to the cation exchange capacities of the samples.     The specific surface area values of the samples were found to   decrease in the following order:    Bentonite > Sepiolite > Zeolite > Kaolin (for MB and OP adsorption)    Sepiolite > Bentonite > Zeolite > Kaolin (for PNP and N2 adsorption).
