Adsorption characteristics of Baijiao anthracite coal to iodine and bromine have been systemically studied Adsorption of iodine on coal conforms to Freundlich experiential equation or Langmuir model The kinetics of adsorption of iodine on coal follows the unconventional first order model: q(t)=A[1exp(kt)]n Pore structure of coal adsorbed iodine in aqueous solution gets blurred The q to iodine on the demineralized coal is less than that on original coal, whereas it is larger to bromine The results obtained by desorption experiment, Xray diffraction and FTIR spectroscopy analysis show that the adsorption of iodine and bromine on coal is mainly physical process In addition, direct and alternating current conductivities of coal adsorbed iodine are about two order larger than those of the untreated coal
