        Adsorption of Pb(II) from aqueous solution to Ni-doped bamboo charcoal

        Yin Wang,Xuejiang Wang,Xin Wang,Mian Liu,Zhen Wu,Lianzhen Yang,Siqing Xia,Jianfu Zhao 한국공업화학회 2013 Journal of Industrial and Engineering Chemistry Vol.19 No.1

        Bamboo charcoal (BC) obtained by pyrolysis of Makino bamboo in the absence of oxygen was used as support for the preparation of Ni-doped adsorbent (Ni-BC). The low-cost composite was characterized and used as an adsorbent for Pb(II) removal from water. The results showed that both BET surface area and total pore volume of Ni-BC increased. The adsorption of Pb(II) strongly depended on solution pH,temperature and ionic strength. The adsorption isotherms followed Langmuir isotherm model well, and the maximum adsorption capacities of Pb(II) at 298 K were 25.0 and 142.7 mg/g for BC and Ni-BC,respectively. The adsorption processes were well fitted by pseudo-second-order kinetic model. Thermodynamic parameters showed that the adsorptions of Pb(II) onto both adsorbents were feasible,spontaneous, and exothermic under the studied conditions. The spent Ni-BC could be readily regenerated for reuse.
