The adsorptions of nicotine at 298 K from aqueous solution onto natural Wyoming
montmorillonite (Wy-M), acid-activated montmorillonite (Wy-MA) and alkali-activated
montmorillonite (Wy-MAL) were investigated. The Wy-MA and Wy-MAL samples were
obtained by acid and alkaline modification process using HCl and Na2CO3, respectively. The
changes in the chemical and phase composition, as well as the textural properties of the
starting and modified samples were monitored using X-ray diffraction, infrared spectroscopy
and physisorption of nitrogen. The adsorption experiments were performed in a batch system.
The adsorption was monitored with respect to contact time, nicotine initial concentrations
(0.1-1mM), mass of adsorbent (12.5 - 200 mg) and pH (2-11). The concentration of nicotine
was analyzed before and after the adsorption tests using a UV-Vis spectrophotometer at
λmax=261 nm. It was estimated that the equilibrium time for Wy-M and Wy-MAL was 60 min,
and 20 min for Wy-MA. The a...dsorption study showed that the alkaline modification of
montmorillonite slightly affected the adsorption of nicotine (qe = 0.27 and qe = 0.24 mmol/g,
for Wy-M and Wy-MAL, respectively). On the other hand, acid modification significantly
improved adsorption capacity of montmorillonite (qe= 0.52 mmol/g ). The adsorption results
were fitted by Langmuir, Freundlich and Sips adsorption isotherms.
