  • 摘要: 利用NaHSO3作为还原剂制备石墨烯气凝胶（graphene aerogels，GAs），利用二硫苏糖醇作为掺杂剂以及还原剂制备掺硫石墨烯气凝胶（Sulfur-doped graphene aerogels，SGAs）.通过表征可以看出，与GAs电极材料相比，SGAs电极材料具有更大的比表面积以及孔径分布，更有利于电吸附去除溶液中的Pb2+.对比研究在不同工作电压、进水溶液的浓度以及进水流量三个实验条件下两种材料的电吸附性能，在工作电压为1.2 V时SGAs电极具有最好的去除率为36.29%.当进水流量为15 mL·min-1时SGAs与GAs均具有最高的去除率，分别为37.8%、34.1%.在不同进水浓度下，SGAs的去除率均比GAs电极材料去除率高.两种电极材料在不同进水浓度下均满足进水Pb2+离子的浓度越高，吸附量越高.同时经过10次的吸附/脱附电吸附循环实验可以看出两种材料均具有较好的循环再生性能.
    Abstract: Graphene aerogels (GAs) were prepared by using NaHSO3 as a reductant, and sulfur-doped graphene aerogels (SGAs) were prepared by using dithiothreitol as dopant and reductant. It was observed that the SGAs electrode material had larger specific surface area and pore size distribution compared with Gas through characterization, which was beneficial to Pb2+ removal. The electrosorption properties of the materials were also compared at different working voltages, influent solution concentrations and influent flow rates. The highest removal rate of SGAs electrode was 36.29% when the working voltage was 1.2 V. When the influent flow rate was 15 mL·min-1, both SGAs and Gas had the superior removal rate, which were 37.8% and 34.1%, respectively. The removal rate of SGAs was higher than that of GAs with different influent concentration. For both electrode materials higher adsorption capacity was obtained at higher influnt Pb2+concentrations. The two electrode materials both had goog recycling performance after ten adsorption/desorption experiments.
