非均相Fenton狗毛固体催化剂在活性染料模拟废染液脱色中的应用研究

摘要

以狗毛作为催化剂载体,采用浸渍法负载Fe3+,制备了非均相Fenton反应催化剂,并将其用于催化活性蓝M-B模拟废染液的脱色.结果表明：在初始染料质量浓度为100 mg/L的50 mL模拟废染液中,添加Fe3+吸附量为33.0 mg/g的狗毛非均相Fenton反应催化剂0.4 g以及30%的H2O20.4 mL/L,脱色液pH控制在6左右,室温(25℃)下,脱色反应120 min,活性蓝M-B脱色率可达85%.%Fenton reaction heterogeneous catalyst was prepared using dog hair as the catalyst carrier with impregnation method loading Fe3+, which was catalyzed the decoloration of Reactive Blue M-B simulated dye wastewater. The experimental results showed that: the initial dye concentration was 100 mg/L of simulat-ed waste dye 50 mL, addition 0.4 g of heterogeneous Fenton catalyst dog hair with 33.0 mg/g of Fe3+ adsorp-tion amount and 0.4 mL/L of 30% H2O2, decoloration solution pH was control ed at about 6, reacted at room temperature (25℃) for 120 min, the decoloration rate of Reactive Blue M-B could reach 85%.
