Kinetic and thermodynamic parameters of nicotine adsorption onto acid-activated standard
Wyoming clay were investigated to obtain the optimum conditions for adsorption. The
nicotine adsorptions were performed in a batch system, using 0.75 mM solution of nicotine,
the mass of adsorbent of 25 mg at native pH=9.26, in temperature range from 25°C – 60 °C.
The pseudo-first (PFO) and pseudo-second kinetics (PSO) models in both linear and nonlinear
forms were apied for experimental data in the temperature range 25 °C – 60 °C. Error
analysis parameters such as correlation coefficient (R2) and 2 (chi-square) have been used to
determine the best kinetics interpretations of adsorption data. The analyzed parameters
suggested that nicotine adsorption can be best described by tested models in the following
order: non-linear PSO = linear PSO >non-linear PFO>linear PFO. The Weber-Morris intraparticle
diffusion model was applied in order to predict the rate-limiting step. The calculated
val...ues for Cid were in the range 0.452 mmol g-1 to 0.484 mmol g-1, indicating effective role of
the boundary layer on the adsorption rate. Thermodynamic study revealed that nicotine
adsorption i\ \] Q K\ ¡G°=-18.93 kJ mol-1) physisorpton process with calculated value
of enthalpy change of 4.99 kJ mol-1 and activation energy of 21.95 kJ mol-1.
