چکیده
Adsorption capacity of 4-chloro-2-nitrophenol (4C2NP) onto nano-Ti02 from aqueous solutions was
investigated in a batch system by considering the effects of various parameters like contact time, nano-
TiO2 dosage, initial pH and initial 4C2NP concentration. Optimum conditions for 4C2NP adsorption
were found to be initial pH z 2, nano-TiO2 closer- 0.01 g and equilibrium time 1 h. The adsorption
kinetic data were analyzed using pseudo-first and pseudo-second order models. It was found that the
pseudo-second-order kinetic model was the most appropriate model, describing the adsorption kinetics.
The thermodynamic parameters such as AG°, MP and AS° were computed from the experimental data.
These values show that the adsorption of 4C2NP onto nano-Ti02 is spontaneous and endothermic.
