Effect of oxidative modification of activated carbon for the adsorption behavior of nicotine

다국어 초록 (Multilingual Abstract)

The adsorption of nicotine onto activated (AC) and AC modified (MAC, by contact with ammoniumpersulfate) can be described well using the Langmuir model with maximum adsorption capacities of 552and 640 mg g 1, respectively. Nicotine has high ‘hardness’ and appears to adsorb most readily on theincreased concentration of ‘hard’ MAC edge functional groups. Adsorption is shown to be exothermic;with enthalpy of 10 and 16 kJ mol 1 for AC and MAC, respectively. The negative free energy andpositive entropy of adsorption indicate a spontaneous process and a strong affinity between aqueousnicotine and AC or MAC.
