Many sandstone-type uranium mineralization sites have been identified along the northern margin of the Qaidam Basin in North *** tectonism and multistage magmatism that occurred there have restricted the use of conventional techniques(petrogeochemistry)to deduce the sources of detritus and uranium in these sediments,and to further explore the sandstone-type uranium *** this study,U-Pb geochronological and Hf isotopic analyses were conducted on detrital zircon grains collected from Jurassic to Paleogene sandstones exposed in the Yuqia area of the Qaidam *** results indicate that the U-Pb ages of the analyzed zircon grains are clustered into four groups,285–229,498–401,999–806,and 2520–2305 ***ε_(Hf)(t)of the analyzed zircon grains ranges from-21.9 to+10.5,with two-stage Hf model ages(T_(DM2))concentrated between 2.1 and 1.3 *** on paleocurrent studies and results of petrological,detrital zircon geochronology,and Hf isotopic analyses,the Jurassic sediments in the Yuqia area were likely derived from the tectonic belt along the northern margin of the Qaidam Basin,such as the Qilian Mountains and the Quanji *** contrast,the Paleogene sediments were probably sourced from the northern margin of the Qaidam Basin and the Qilian *** uranium and thorium content and Th/U value of the rock mass and sedimentary strata in the source area show that the Indosinian Early Paleozoic uranium-rich granites and the Middle Jurassic uranium-rich strata of the northern margin of the Qaidam tectonic belt in the source area provide dual uranium sources for the Yuqia sandstone-type uranium ***,the study area appears to be favorable for sandstone-type uranium mineralization and may have potential for uranium prospecting.

为研究江西于都南部地区耕地土壤重金属污染状况,对所采集的表层土壤样品进行Cr、Ni、Cu、Zn、Cd、Pb、As、Hg等重金属元素测试,研究其空间分布特征,并采用多种评价模型开展生态评价。结果表明,Cr、Ni、Cu、Zn、Cd、Pb、As、Hg含量分别是于都县土壤背景值的1.18、1.24、1.69、1.41、5.79、1.25、2.27、1.41倍。单因子污染指数显示As、Cd污染最严重,是潜在生态风险最主要的贡献因子。内梅罗综合污染指数显示重金属超标率达20.7%。地累积指数显示As污染最严重,其次是Hg、Ni、Cd。8种重金属元素变异系数均为0.45~5.14,属强变异。相关性分析显示,除Hg外的其他重金属间相关性均较强,而且与pH存在显著或极显著正相关,因此可以通过调节土壤pH值,降低土壤中重金属元素的毒性。主成分分析结果显示,Cu、Zn、Cd、Pb、As主要来源于人为采矿活动,Cr、Ni主要来源于土壤母质。

A novel material, alumina supported on carbon nanotubes (Al2O3/CNT), was prepared from carbon nano-tubes and A1(NO3)3. X-ray diffraction (XRD) spectra demonstrate that alumina is amorphous, and scanning electron microscope (SEM) images show that CNT and alumina are homogeneously mixed. Furthermore, the fluoride adsorption behavior on the surface of Al2O3/CNT has been investigated and compared with other adsorbents. The results indicate that Al2O3/CNT has a high adsorption capacity, with a saturation adsorption capacity of 39.4 mg/g. It is also found that the adsorption capacity of Al2O3/CNT is 3.0-4.5 times that of γ-Al2O3 while almost equal to that of IRA-410 polymeric resin at 25°C . The adsorption isotherms of fluoride on Al2O3/CNT fit the Freundlich equation well, and optimal pH ranging from 5.0 to 9.0.

Detection and analysis of volatile organic compounds (VOCs) as pollutants in the atmosphere and liquids are of great significance because of the detrimental effects of VOCs. A polymer-coated graphene micro-tube piping (GMP) structure with a cross-linked and interconnected channel network was synthesized for liquid sensing. By virtue of their unique cross-linked and interconnected channel network configuration, polycrystalline conformation, and the support of a polymer layer, the resistivity of the 3D hollow micro-tubing GMPs was sensitive to strain, ensuring high sensitivity of the liquid sensor (R/R 0 of ∼4 × 103% for pure acetone and R/R 0 of ∼105% for 0.01 wt.% acetone solution). Due to the capillary force, the interfaces of the 3D structures can speed up the penetration of solvents into the polymer, thus promote distinct selectivity within seconds and significantly decrease the response time. Owing to their good selectivity, high sensitivity, rapid response and flexibility, and the ease of use of the sensors and the simplicity of the fabrication processes, the GMP/polymer composites should be a good candidate for liquid sensing.
