| Abstract: | In an attempt to remove oily substances from water, a ZnCl2 activation method was adopted to prepare adsorbents from oily sludge. On preparing oily sludge adsorbents, the nature of the adsorbents was influenced by the activation concentration of ZnCl2 in solution, ratio of solid to liquid volume, activation temperature, and activation time. Meanwhile, the research also analyzed the BET surface area and pore distribution. The results showed the optimum properties, technically and economically, as follows 5.0 mol·L-1 of ZnCl2 solution, 1:1.5 ratio of solid to liquid volume, 450℃, and 2 h of activation time. The BET surface area of the adsorbent was 316.088 2 m2·g-1, and the removal rate of oil from water was 94.61%. |
