The Fe^0 concentration and pH had optimal values during the decolorization of X-BR in Fe^0-anaerobic biological system. When Fe0 dose, initial pH value and X-BR concentration were 400 mg/L, 7 and 100 mg/L respectively, the decolorization rate of X-BR in the integrated system could reach up to 90% after 68 h reaction. Compared with pure Fe^0 and pure microorganism treatment systems, it could be improved about 40% under the same experimental conditions. In addition, the analysis result of UV-vis spectrogram indicated that Fe^0 could promote effectively biodegrading of anthraquinone dye X-BR and its intermediate products.

结果表明，在Fe^0-厌氧微生物体系中，Fe^0投加量和pH值均存在最适宜值，当两者分别控制在400mg/L和7，染料初始浓度和反应时间分别为100mg/L和68h时，该体系脱色率可达到90%以上；与相同反应条件下的纯Fe^0、纯厌氧微生物体系相比，该体系的脱色率提高近40%根据紫外可见光谱分析，Fe^0可有效促进厌氧微生物对X-BR及其中间产物的降解，实现完全脱色。

Based on the changes in the spectrum characters of guest molecules producedthrough inclusion complex formation with cyclodextrins, we have carried out two aspects of investigation:First, the mechanisms for the host-guest recognition reactions have been studied, such as the interactions between 3-CD and curcumin, the main constituent of the rhizomes of the plant Curcuma longa, the recognition of p-CD towards rubidate, the effective component of the Chinese traditional medicine madder, and the reactions of p-CD towards the antileprotic drug dapsone and the antiinflammatory drug nabumetone: The formation of supramolecular complex between P-CD and guest molecule has been discussed and verified in virtue of multitudinous means such asultraviolet-visible absorption, fluorescence emission, infrared spectrogram and so on. The influence of addition of linear alcohols on the supramolecular system has been studied and the reason why the noncovalent interactions in the three-component system could result in a decrease in the apparent association constant of the inclusion complex has been revealed.
