The polyethyleneimine dithiocarbamate was employed as polymers to synthesize Fe3Pt-Ag nanocomposites by using the seed deposition method. Fe3Pt-Ag nanocomposites were utilized for the catalytic degradation of methyl orange（MO） in the presence of NaBH4. Fe3Pt-Ag nanocomposites showed good chemical catalytic activity and stability in pollutants degradation. Furthermore, Fe3Pt-Ag nanocomposites can keep their efficiency till four cycles. The results suggest that the nanocatalysts with recyclability have broad prospects in environmental conservation applications.

[目的]珊瑚岛地下淡水透镜体是维持岛上居民生产生活、生态涵养所必需的重要资源。准确识别珊瑚岛地下淡水透镜体的形态,揭示地下淡水补给机制,是珊瑚岛地下水资源评价的重要基础,对实现科学管理海岛地下水资源至关重要。[方法]本文以西沙群岛的东岛为研究对象,结合水文地质调查,对高密度电阻率法实测剖面数据进行反演解译,基于电阻率和地下水总溶解固体浓度关系识别了咸淡水界面。[结果]①根据高密度电阻率法反演电阻率首次识别了西沙东岛地下淡水透镜体发育特征,该方法在西沙珊瑚岛具有较好的适用性;②东岛淡水透镜体主要发育于岛屿西北和南侧沙堤,厚度较薄,仅3~7m,局部地区甚至无地下淡水;③东岛地下咸淡水界面形态说明沙堤以内植被根系吸水是造成淡水透镜体较薄的主要原因,植被分布对东岛地下淡水资源具有重要影响。[结论]在保护西沙珊瑚岛生态系统的前提下,适当减少人工椰树林种植面积,可有效增加岛屿降雨形成的地下淡水资源,有利于发挥珊瑚岛地下淡水透镜体对岛屿水安全的保障作用。
