D301树脂对三原色派拉丁染料的吸附

摘要

采用D301树脂对经絮凝工艺处理后的三种模拟派拉丁印染废水中的三原色染料进行吸附.实验结果表明:在D301树脂的粒径为425～600 μm、模拟印染废水pH为2、反应温度为30℃、D301树脂加入量为3 g/L、派拉丁粉红BN、派拉丁蓝RR和派拉丁黄GR三种模拟印染废水的初始质量浓度分别为207.98,315.00,67.35 mg/L的条件下,三种派拉丁染料的去除率分别为88.99％,93.24％,94.96％.%Three simulated dyeing wastewaters containing tricolor Palatin dyes were treated first by flocculation and then by D301 resin adsorption. Under the conditions of D301 resin size 425 ~ 600 |xm, wastewater pH 2, reaction temperature 30 t, D301 resin dosage 3 g/L, and the initial concentrations of Palatin pink BN、Palatin blue RR and Palatin yellow GR are 207.98, 315.00, 67.35 mg/L respectively, the removal rates of the 3 dyes are 88.99% ,93. 24% ,94.96% , respectively.
