摘要

  • 摘要: 以北京大兴南海子湖表层沉积物为研究对象,测试分析了0.147~0.246 mm(细砂)、0.074~0.147 mm(极细砂)、0.0385~0.0740 mm(粉粒)和R2>0.90)。粒径对单位质量泥沙吸附磷量具有明显影响,粉粒粘粒混合物>粉粒>细砂>极细砂。总体上,泥沙有机质(OM)、TP、Fe、Al、Ca和Mn含量随粒径的减小而增大,且粘粒对其影响较大。不同粒径泥沙(OM)、Fe、Al、Ca和Mn含量之间存在极显著正相关关系(PXm)和饱和吸附量(Cse)具有正效应,其中Al含量对该参数的影响更为显著。这说明泥沙对磷的吸附行为可能受到粒径和化学成分的共同影响。
    Abstract: The surface sediments samples were collected from Nanhaizi Lake in Beijing. The phosphorus sorption behaviors on four particle size sediments including 0.147~0.246 mm(fine sand), 0.074~0.147 mm (very fine sand),0.0385~0.0740 mm(silt),R2 of>0. 90). The maximum sorption mass (Xm) of different size particles was in the order of silt and clay>silt>fine sand>very fine sand. The content of OM, TP, Fe, Ca, Al and Mn increased with the decreasing particle size and the fraction of clay particles had more important effect on them than other particles. There was a significantly positive correlation (PXm and equilibrium concentration (Cse) on the sediments. These results indicate that the phosphorus sorption could be jointly affected by both sediment particle size and chemical composition.
