The contents of inorganic arsenic in three kinds of algae are determined using this method. The result shows that algae have a low content of inorganic arsenic, complying with the results frequently reported in recent years, in which combination of some testing methods such as HPLC-ICP- MS and HPLC-HGAFS are used. Compared with these results, the results obtained from national standard methods are relatively high, due to the inapplicability of atomic fluorescence method.

并运用本法检测了海带、裙带菜、紫菜等三种海藻中的无机砷含量，发现海藻中的无机砷含量并不高，原国标方法检测的结果就相对较高，原因主要是原国标方法中的原子荧光法不适合于海藻类样品，检测结果与近来国内外报道较多的HPLC-ICP- MS、HPLC—HGAFS等联用技术检测海藻类物质中无机砷含量结果基本吻合，结果良好。

The Diels-Alder cycloadditions of [60] fullerene for preparation of optical limitingmaterials are discussed in chapter 3 and 6. Soluble cycloaddition derivatives of 〓aresynthesized by the reaction of 〓 with indene,1,1'-biindene andcyclopentadiene derivatives.〓Particular, the Diels-Alder cycloaddition of 〓 with1,1'-biindene under controlled conditions affords the stable monoadduct 〓〓of novel structure, which was confirmed by HPLC, FTIR, FD-MS,〓NMR,〓 NMR, HMQC and HMBC spectra, Its two bridgehead cage carbons resonate at70.91ppm, The 〓 NMR spectra showed 38 lines consistent with the 〓 symmetryassociated with [6,6] addition. The 〓 shows similar optical limitingproperties to that of 〓 in toluene for 8ns laser at wave length 532nm. Moreover, thehigh solubility of this adduct in polar solvents such as THF, acetone enables itsincorporation into sol-gel glass matrix. The thin films prepared via the sol-gel methodshow improved OL behaviour compared to those of 〓. The langmuir-Blodgett filmformation and uv-visible absorption of 〓 are also investigated. LBmonolayer of this compound is prepared on the air-water interface at 〓 mol/l. In chapter 4, three water-soluble derivatives of [60] fullerene: fullerol(1), theaddition product (2)of fullerol (1)with polyvinylpyrrolidone and fumaric acidderivative of 〓(3) are synthesized and characterized.
