Iron , aluminium and lanthanon complex dyes , the pH value of reaction system was 7 . 5 ~ 8 . 5 , whereas that in preparation tmperature were all 75 ~ 80 ℃ . The yield were above 85.0 % .

pH值对降解速率的影响因染料的不同而有所差别。（4）非均相UV-Fenton体系降解金属络合染料过程中，有铁离子溶出现象。

The effect of initial pH values on degradation rate was different because of the different structures of dye . ( 4 ) Iron leaching could be detected during the degradation of metal complex dyes by heterogeneous UV - Fenton process .

初步研究非均相UV-Fenton体系对金属络合染料的处理是否能同时满足高效降解矿化有机配体和高效吸附去除重金属离子这两方面的要求。

Whether the heterogeneous UV-Fenton process could treat the metal complex dyes with high efficiency in both treating organic structure and removing heavy metal ions were studied primarily .

通过紫外-可见光谱分析，定性确认了络合染料的结构，其结果表明，偶氮金属络合染料的最大吸收波长λmax分别在392nm～500nm之间，表现为色泽鲜艳的黄色和红色。

By the visible spectra analysis , the structure of the complexed dyes were determined and the metallized complexed dyes characterized , which showing that the maximum absorption wavelength of metallized complexes is between 392nm ~ 500nm , which showed the color of fresh yellow and red .

金属络合染料是一类重要的染料分支，而偶氮金属络合染料，在整个金属络合染料中当视为最重要的一类，主要用于蛋白质纤维（羊毛，蚕丝）和聚酰胺纤维的染色。

The metallized complexed azo dyes are important metallized complexed dyes used for protein ( wool and silk ) and polyamide fibers .

本文对这类染料的大部分品种进行曝光，以使其避免被选用，并就酸性金属络合染料代用品的重要品种加以评述。

Most of them were exposed in order to avoid being selected and the substitutes of metal complex acid dyes were commented .

同时，由于铜、锌盐的价格低于铬盐和钴盐，因此，研制新的环境友好的偶氮铜、锌金属络合染料具有重要意义。

At the same time , the price of copper salt and zinc salt is far lower than chromium salt and cobalt salt .

传统的偶氮金属络合染料，含有铬、钴等重金属离子，在染料的合成及印染过程中，产生大量的有毒废水，严重危害周围水系的生态环境。

Conventional metallized azo dyes , containing heavy metal ions such as chromium ( III ), cobalt (ⅱ) produce a large amount of industrial wastewater , which seriously polluting the ecological environment .

结果表明此种新型染色增艳剂对酸性和直接染料具有很好的增深、增艳作用，对金属络合染料没有增艳作用，烘干后使用增艳效果消失。

The results showed that the dyeing brightening agent can brighten and deepen direct and acid dyes , but it has no effect on metal complex dyes and its brightening effect disappears after being baked .

结果表明，实验用菌可对溶剂型金属络合染料起明显的脱色作用，经驯化的白腐真菌处理染料液72小时脱色率高达90%以上。

The result indicated that the WRF used in the research had obvious decoloring effect on the dyes , about 90 % color from the wastewater could be removed after treatment 72 hours by the acclimated WRF .
