| Abstract: | Preparation of municipal sludge-bentonite granulated absorbent and its adsorption properties used for the Pb~(2+) solution were studied by roasting and oscillating adsorption experiment. The optimum conditions of preparing particle adsorbent were as following: the mass of municipal sludge to bentonite was 6 : 4, particle diameter was 1.2mm, and roasting temperature was 550℃ for 2h. The lead removal rate could be reached to 92.55% when the oscillating adsorption temperature was 25℃, adsorption time was 30 minters, and the solution of pH value was 4 respectively. And the absorbent of adsorption to Pb~(2+) is suit for Langmuir equation. |
