  • 摘要: 污泥炭(SC)灰分含量高，吸附性能差，因而限制了其应用范围。使用3-氨基丙基三乙氧基硅烷(APTES)对污泥炭进行改性，提高其对重金属的吸附能力。结果表明：APTES成功地负载到污泥炭上；在25 ℃ 时，APTES-SC对Pb(II)的吸附量是SC的8倍；吸附量随溶液pH (1~8)的增大而增强。APTES-SC对Pb(II)的吸附行为符合二级动力学模型，等温吸附曲线符合Langmuir模型，吸附过程是自发、吸热反应(ΔG0)。该方法制备的改性污泥基炭是一种能去除废水中Pb(II)的高效吸附剂。
    Abstract: Due to high ash content and poor adsorption capacity of sewage sludge-based carbons (SC), its application field was limited. In this study, 3-aminopropyltriethoxysilane (APTES) was used to modify SC and improve its adsorption capacity for heavy metals. The results showed that APTES was successfully loaded on SC. At 25 °C, the Pb(II) adsorption capacity of APTES-modified SC (APTES-SC) was 8 times as high as that of SC, and increased with pH (1~8) of adsorption solution. Moreover, Pb(II) adsorption kinetics by APTES-SC fitted well to the pseudo-second-order model, and its Pb(II) adsorption isotherm data could be well described by Langmuir model. The above adsorption process was identified as a spontaneous, endothermic one (ΔG0). APTES-SC could be a high efficient absorbent for Pb(II) removal from wastewater.
