The surface area, total pore volume, average pore diameter of TWNC was found as 722.17 m(2) g(-1), 0.476 cm(3) g(-1) and 2.644 nm, respectively. The effects of solution pH, adsorbent dose, initial concentration, ionic strength, contact time, and temperature were studied. Adsorption kinetics was found to behest represented by the pseudo second order model. Isotherm data were fitted well to the both Langmuir and Freundlich models. Maximum adsorption capacity was found as 68.97 mg g(-1) at 50 degrees C. Thermodynamic parameters showed that the process was spontaneous and endothermic.
