The photocatalytic degradation property of ZnM2O4 (M=Cr, Mn, Fe) nanoparticles was investigated by using methyl orange, acid red B and reactive red K-2G as model pollutants under the irradiation of a mercury-vapor lamp (λ＞400 nm) or sunlight. The degradation rates of the above three dyes by ZnM2O4(M=Cr, Mn, Fe) are over 80％, 57％ and 39％, respectively within 2 h. It is found that ZnM2O4 (M=Cr, Mn, Fe)has a novel photocatalytic behavior for dyes under visible light irradiation.

The solvent effect of five azo-metal complex dyes in fourteen solvents was studied with Nicol theory for the first time, and the main factors affecting the absorption spectrum of azo-metal complex dyes were found.

首次用Nicol理论研究了五种金属络合偶氮染料在14种不同溶剂中的溶剂效应，找到了影响溶液中金属络合偶氮染料电子吸收光谱的主要因素。

The adsorptive effect of chitosan on acidic dye follows a sigmoidal trend. The chitosan-woven fabric after 98% de-acetylation achieved 98% and 95% dye adsorption in reactive dyes; and achieved 93% and 92% dye adsorption in reactive dyes in eight days. The higher the degree of de-acetylation, the better the dye adsorption.

使用去乙醯化98%的几丁聚醣含浸织物吸附材，在经过8天的饱和吸附后，对於种反应性染之吸附效果可达到98%和95%；且对於种酸性染之吸附效果也可达到93%和92%，由此可知去乙醯化程越高，对染的吸附效果越好。

Various chrome complex dyes(1:1 ratio) of mordant black 1,mordant black 7,mordant black 9 and mordant black 11 have been synthesized and sodium dichromate is been used as mordant agents instead of Cr3+ to oxidate dyes sufficiently.

还设计合成了媒介黑1、媒介黑7、媒介黑9和媒介黑11的高水溶性1∶1络合染料，重铬酸钠作为铬化试剂，染料得到了充分的氧化，无色配体多羟基羧基酸的引入使染料有很好的水溶性，该实验路线未见报道。

In a word, sulfonamide dyes exhibit better color fastness properties on three sorts of hydrophobic fabrics, especially for sublimation fastness, in comparison with the dyes without sulfonamide group in their structures.

与结构中不含磺酰胺基的染料相比，磺酰胺染料在三种疏水性织物上具有更好的色牢度，特别是耐升华牢度明显提高。

Then two series of yellow sulfonamide dyes are synthesized by the reaction of the sulfonyl chlorides and ammonia or different fatty amines in the presence of acid-binding reagent. The structures of sulfonyl chloride intermediates and sulfonamide dyes are confirmed by FTIR,~1H NMR and mass spectrometry.

将所合成的磺酰氯化合物在缚酸剂作用下分别与含有不同碳数的饱和脂肪胺发生缩合反应，合成了两个系列黄色偶氮型磺酰胺染料，并利用红外光谱、核磁共振氢谱和质谱表征了磺酰氯中间体和磺酰胺染料的分子结构。
