掺杂Fe3+的纳米TiO2光催化降解氮氧化物研究

利用Fe(NO3)3*9H2O,采用浸渍的方法,制备了掺Fe3+的纳米TiO2.讨论了此种纳米TiO2对氮氧化物的光催化效率,并分析了Fe3+在催化过程中的作用.试验结果表明:Fe3+明显提高了纳米TiO2的光催化性能;在室内自然光作用下对较高质量浓度的氮氧化物均具有较高的光催化效率.通过对TEM照片和XRD谱的分析,从能级理论解释了Fe3+提高催化活性的原因.     

Cryptomelane（KxMn8-xO16）： Natural active octahedral molecular sieve（OMS-2）

The Xiangtan manganese deposit (XTM) used to be considered a supergene oxide manganese ore in South China. We reported a new identification of the naturally outcropping cryptomelane by examining the physical, chemical and structural features of the XTM supergene oxide manganese ore. The MnO2 content was over 90%, K2O more than 3%, and water from 2.2%-3.1% which is similar to one in zeolite. The cell parameters of the cryptomelane were given as a0 = 0.9974 nm, b0 = 0.2863 nm, c0 = 0.9693 nm and β= 91.47°. There was a larger pseduotetragonal tunnel in the natural cryptomelane that was formed by [MnO6] octahedral double chains with aperture of 0.462×0.466 nm2, filled with K cations resulting in some Mn3+ substituting for Mn4+ to balance the negative charges of structure. The finding is important not only for prospecting manganese resources in South China, but also in application of octahedral molecular sieve of natural cryptomelane as that developed in the tetragonal molecular sieve of natural zeolite o     

德兴斑岩铜矿成矿流体演化与来源的流体包裹体研究

主要研究了德兴斑岩铜矿床不同期次脉石英及花岗闪长斑岩石英斑晶中流体包覆体的特征，测定了流体包裹体的均一温度和冰点，估算了成矿流体的盐度、密度等参数．结合花岗闪长斑岩与石英脉中石英氢氧同位素数据的讨论分析，对流体的演化过程和来源进行了探讨．研究表明花岗闪长斑岩石英斑晶中的包裹体代表了岩浆流体的特征，石英脉中的包裹体记录了岩浆流体演化成成矿流体的特征。研究证实成矿流体主要由岩浆流体而来，成矿流体演化晚期有大气降水的加入。     

氧氟沙星荧光光度法测定痕量铁

研究了在HAc-NaAc缓冲溶液中氧氟沙星与Fe(Ⅲ)的络合反应，结果表明：在pH=4．0的缓冲溶液中，氧氟沙星有稳定而较强的荧光；与Fe(Ⅲ)络合后，荧光强度减弱．最大激发及发射波长为324nm和498．6nm，Fe(Ⅲ)的质量浓度在0．56～3．08mg／L范围内，荧光强度与浓度呈良好的线性关系．检出限为0，076mg／L，常见的共存离子不干扰其测定．本方法用于水中痕量铁的测定，得到了满意的结果。     

Loess-soil sequences in southern Anhui Province： Magnetostratigraphy and paleoclimatic significance

Two parallel loess-soil sequences from Xuancheng and Fanchang in southern Anhui Provinces are dated using geomagnetic and luminescence methods.The Brunhes/Matuyama(B/M) reversal boundary is recognized within the lower part of the so-calles Vermiculated Red Soil (VRS) in the Xuancheng section while the entire Fanchang sequence is of Brunhes age.This indicated that the most recent VRS in southern China,a stratigraphic marker and an indication of extremely warm-humid conditions,was formed during the middle Pleistocene,chronologically correlative with the S4 and S5 soil units in northern China.Microscopic and sedimentologic in vestigations reveal that eolian deposition started in this region at about 0.85 MaBp,roughly synchronous with the well-known Mid-Pleistocene climate change of global significance.The strengthening of both summer and winter monsoon circulations and the consequent river hydrological changes at that time would have provided favorable conditions for sustained eolian deposition in the middle-lower reaches of the Yangtze River since 0.85 MaBP.
