AB  - Activated carbon was prepared from Enteromorpha prolifera (EP) by H3PO4 
      activation in the presence of doped cetyl trimethyl ammonium bromide (CTAB), 
      producing EPAC-CTAB. The thermal decomposition process of the activated carbon 
      substrate was identified by thermo-gravimetric analysis. Scanning electron 
      microscope (SEM), N2 adsorption/desorption, Fourier transform infrared 
      spectroscopy (FTIR), Boehm titration, and X-ray Photoelectron Spectroscopy (XPS) 
      were employed to characterize the physicochemical properties of native EPAC and 
      EPAC-CTAB. EPAC-CTAB exhibited smaller surface area (689.0m(2)/g) and lower total 
      pore volume (0.361cm(3)/g) than those of EPAC (1045.8m(2)/g and 1.048cm(3)/g), 
      while the number of acidic groups, oxygen and nitrogen groups on the surface of 
      EPAC-CTAB increased through CTAB doping. The batch kinetics and isotherm 
      adsorption studies of nickel(II) onto the adsorbents were examined and agreed 
      well with the pseudo-second-order model and the Langmuir model. The maximum 
      adsorption capacity determined from the Langmuir model was 16.9mg/g for EPAC and 
      49.8mg/g for EPAC-CTAB. Under acidic condition, the adsorption of nickel(II) onto 
      EPAC and EPAC-CTAB was hindered due to ion competition and electrostatic 
      repulsion. The results indicated that using CTAB as a dopant for EPAC 
      modification could markedly enhance the nickel(II) removal.
