Gongye shui chuli, 2003 使用还原型脱色剂对直接染料染色废水进行脱色处理，重点研究了脱色剂用量、反应温度、pH和时间等因素对脱色反应的影响。并且将脱色后的染色废水回用于织物染色中，在染色织物的颜色特征和牢度方面进行了比较。结果表明，脱色温度的升高有利于染料的脱色，尤其对于水溶性较差的品种，脱色剂用量的增加能够促进染料的脱色率的升高。另外三种染料在自来水和回用水中的的染色织物的染色表面深度和牢度比较接近，而且染色织物之间的色差较小，这说明脱色废水可以回用于直接染料的染色中。

Studies of optical absorption of azo pigment from 1-aminoanthraquinone(含蒽醌基单偶氮染料吸收光谱研究)
Zhejiang Daxue xuebao. Lixue ban, 2002 由1-氨基蒽醌与不同偶合基合成了8个含蒽醌基单偶氮染料,对其进行了元素分析、红外光谱和紫外光谱表征。对其紫外吸收光谱的研究表明,当偶合基由2-羟基-3-氨替酰氨萘酚变为2-羟基-11氢-苯并咔唑-3-氨替酰氨萘酚时,偶氮染料的吸收红移130 nm。用紫外灯光和红外灯光对8个偶氮染料进行了光照实验,发现紫外光照会引起偶氮染料DMF稀溶液减色,没有观察到N=N双键的顺反异构吸收变化。
