摘　　要：采用自制实验装置,研究了太阳光照射玻璃弹簧负载TiO2膜对活性黄棕K-GR脱色的影响。结果表明,在水溶液浓度15 mg.L-1、pH 3、流速20 mL.s-1、太阳光强度1 200μW.cm-2以上,反应时间3 h时,脱色率为95%以上。Solar photocatalytic decoloration of reactive yellow brown K-GR was studied using self-designed reactor. TiO2 was used as photocatalyst, immobilized on glass spring. The results showed that the decoloration rate of reactive yellow brown K-GR was over 95% under the condition of initial concentration 15 mg·L^-1, pH 3, velocity of flow 20 mL · s^-1 , solar radiation strength 1 200 μW · cm^-2 and reaction time 3 h.
