共振光散射技术及其在分析化学中的应用研究

随着经济全球化速度的不断加快，我国改革开放的不断深入，如何维护国家经济安全已成为一个我们无法回避的问题。我国作为发展中国家中最大的引资国，在吸收、利用外国直接投资（FDI）的过程中如何最大限度地维护国家经济安全，保护和促进民族工业的发展，利用FDI的产业带动效应优化产业结构，提高我国在国际分工中的产业竞争力，都是我们目前亟待研究解决的问题。特别是在我国即将加入WTO，需要进一步开放国内市场的形势下，对这些问题的研究更具有现实性和紧迫感。这也正是本论文选题的主要动机。 本论文共六章，分两部分对中国利用FDI过程中如何维护国家经济安全的问题进行研究和阐述。 第一部分（论文的第一、二、三章）主要...Resonance Light Scattering (RLS) technique is a novel analytic technique using the normal fluorospectrophotometer to detect.

报道了厦门西海域拟疏浚沉积物中的重金属含量水平及分布,并对其污染状况进行了潜在生态危害评价,为进一步开展疏浚物去污染技术研究提供了科学依据.研究结果表明:与其他海域的相比,马銮湾及其湾口外、筼筜湖的Cd、Hg、Cr、Zn含量较高.综合来看,厦门西海域拟疏浚沉积物重金属含量不很高(RI<150),属于轻微生态危害.但东渡码头外的X4站、马銮湾M2站沉积物中的Cd,及马銮湾M2站和筼筜湖Y2站沉积物中的Hg含量(40≤Er<80)都达到中等生态危害程度.Sediment samples were collected from dredging areas of Xiamen Western Harbor,and analyzed to determine the concentration and distribution of heavy metals.Results showed that the level of heavy metals in the sediments of dredging area were low,but Cd,Hg,Cr,Zn from Maluan Bay and Yuandang Lake were a little higher.Here a potential ecological risk index was used to assess the pollution effect of heavy metals.It indicated that for most heavy metals the ecological risk is light.Potential ecological risk of Cd from Dongdu Wharf(X4) and Maluan Bay(M2),Hg from Maluan Bay(M2) and Yuandang Lake(Y2) are in the middle level.福建省2004年科技重点项目(2004I001

Speciations of Heavy Metals in the Surface Sediments from Xiamen Western Harbor

采用逐级浸出法对厦门西海域6个表层沉积物样品中重金属(Cd、Cr、Cu、Ni、Pb、Zn)的赋存形态进行分析.结果表明:该海域表层沉积物中各重金属元素主要来源于人为输入的各种活性形态,自然输入的残渣态(RES)所占比例较低(10%～20%),在环境条件变化时具有向水相迁移和为水生物所利用的潜在风险性;其中Cu、Cr和Ni的赋存形态以铁锰氧化态(ERO和MRO)和有机物及硫化物结合态(OSM)为主,Pb和Cd则以碳酸盐态(CARB)、铁锰氧化态和有机物及硫化物结合态为主,Zn的各形态所占比例相对比较平均.此次研究对该海域表层沉积物中重金属的赋存形态特征有了基本了解,有助于进一步研究金属元素在近海环境中的迁移和形态转化机制.A sequential extraction procedure was employed to study the chemical speciations of heavy metals in 6 selected surface sediments from Xiamen Western Harbor.The results indicated that Cd,Cr,Cu,Ni,Pb,and Zn in the sediments were predominated(80%~90%) by the geochemically extractable forms,which mainly originated from anthropogenic sources,and least present in residual form(RES).The dominant proportion of Cu,Cr and Ni was ERO(easily reducible oxides),MRO (moderately reducible oxides) and OSM(organic/sulfide matter),and that of Pb and Cd was CARB(carbonate),ERO,MRO and OSM,whereas Zn was evenly distributed.The results of the present study help to provide a deeper understanding to the distribution pattern of such heavy metals and to undertake further research concerning transition mechanisms of pollutants in marine environment.福建省科技攻关课题(2004I001)资
