چکیده انگلیسی
Adsorption behavior of water, o-xylene and p-xylene vapor to a series of N,N′-hexamethylalkyldiammonium ions [(CH3)3N+(CnH2n+1)(CH3)3N+; where n = 2,3,6,10] exchanged montmorillonites (Kunipia F from Kunimine Ind. Co., Japan; cation exchange capacity of 119 meq (100 g clay)−1 and BENGEL BLIGHT 11 from Hojun, Japan; cation exchange capacity of 78 meq (100 g clay)−1) was investigated. All the organo-clays examined in the present study adsorbed these gases to show their microporous nature. The adsorbed amounts of water, o-xylene and p-xylene increased as the size of N,N′-hexamethylalkyldiammonium was smaller and as the cation exchange capacity of host was larger, showing possible pore volume engineering.
