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.eninfo:eu-repo/semantics/closedAccessAdsorptionBentoniteNicotineOrgano-ClayPharmaceutical CompoundsSorptionWater PollutionArticle676451454WOS:0002567397000092-s2.0-55349095082Q2Q4
