| Abstract: | Static and kinetic adsorption column tests were conducted using the modified permutite as an adsorbent which had been prepared with hydrochloric acid and aluminum sulfate solution.The kinetic column test showed that equilibrium adsorption completed within 30min,which could be described by a pseudo-second-order kinetics model and fit well with Langmuir adsorption isotherm,the max.fluoride adsorption capacity being 5.07 mg/L with the equilibrium constant of 0.0602 L/mg.Defluoridation capacity,which refers to ... |
