摘　　要： 利用模拟混合染料废水,分析了阳离子蓝FGL与酸性、活性、直接、阳离子、分散5种染料混合后的颜色变化机理和染料之间的作用。结果表明:阳离子蓝FGL基本上能与含磺酸基的酸性、活性和直接染料按电荷摩尔比发生作用,与同类的染料不会发生反应,与分散橙SE-B也会通过库仑力发生反应。混合液的色度在有沉淀生成时会变小,这样将节约废水处理的成本。 With simulated mixed dye wastewater, the color-changing mechanism and the interaction between cationic blue FGL and acid, active, direct, cationic, disperse dyes were analyzed. The results showed that： there was reaction between cationic blue FGL and acid, active, direct dyes which contained -SO3 Na according to electricity molar ratio basically, however, reaction won＇t happened between similar kind of dyes. Cationic blue FGL also reacted with disperse orange SE-B by coulomb force. The colority of the mixed dye became smaller when sediments was formed, so that the wastewater treatment cost could be saved.
