| 摘 要： | 本文以大型海藻石莼作吸附剂，对结晶紫等7种不同结构的水溶性染料分子的单水溶液和模拟混合染料废水进行吸附脱色研究，探讨了吸附剂的性能和影响吸附脱色效果的有关因素。结果表明，石莼对大多数水溶性染料具有良好的吸附脱色效果，而且COD去除率高，在染料废水处理中应用前景广阔。

| Abstract: | With Ulva lactuca,one kind of marine macro algae,as an absorbent,the decolorization of dyes from aqueous solution by adsorption was studied.Seven water soluble dyes ,which including crystal violet,alizarin red,neutral red,congo red,malachite green,eriochrome black T and rhodamine B were used.The specific properties of absorbent and the factors affecting decolorization were investigated in detail.The result indicated that the algae had significant effect on decoloring most dyes and the efficiency of COD removal was fairly high.It was reasonable to expect that the algae Ulva lactuca would be vastly applied in processing dey wastewater. |
