摘要
用各种混凝剂对一些单品种染料溶液进行混凝脱色。试验结果表明:混凝法对染料溶液的脱色效果与染料的化学结构,分子量、溶解性能有关。混凝剂的脱色作用和 pH 值适用范围也与染料品种有关。
Single dye solutions are decolored by coagulating agents.The experi- ments show the effectiveness of coagulation decoloration is related to the chemical structure,molecular weight,and solubility of the dye,and the decoloration effects and suitable pH-value range of coagulating agents are related to the variety of the dye.
