| Abstract: | 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-Radushkevich adsorption isotherms. Sorption energy (E) and adsorption capacity (qm)
for N and its derivatives adsorbing on DAB and raw B were estimated using Dubinin-Radushkevich (D-R) equation. Sorption
energy of N and its pharmaceutical derivatives on DAB and raw B increased in order of NA |
