Özet
Dodecylammonium bentonite (DAB) and bentonite (B) were used as sorbents for nicotine (N), nicotinic acid (NA), isonicotinic acid (INA), nicotinic acid hydrazide (NH), and iso-nicotinic acid hydrazide (INH). The obtained data were modeled according to Freundlich and Dubinin-Raduslikevich adsorption isotherms. Sorption energy (E) and adsorption capacity (q(m)) for N and its derivatives adsorbing on DAB and raw B were estimated using Dubinin-Raduslikevich (D-R) equation. Sorption energy of N and its pharmaceutical derivatives on DAB and raw B increased in order of NA < INA < N=INH < NH and INI-I < NH < N < NA < INA, respectively.
