Abstract: The thermodynamic and kinetic characteristics of adsorbing tetrachloroethane on adsorbent M were studied via static adsorption experiments. The experimental results show that the adsorption isotherm of adsorbing tetrachloroethane on adsorbent M is a typical L type adsorption curve, and this adsorption process agrees well with the Langmuir adsorption equation. The thermodynamic parameters illustrate that the absorption of tetrachloroethane on adsorbent M could happen spontaneously, it is an exothermic process attributed to physical adsorption. The dynamics of adsorbing tetrachloroethane on adsorbent M could be described by pseudo-second order kinetic equation. With the increase of adsorption temperature, the initial adsorption rate and adsorption rate constant exhibit an increase tendency.
