| 中文摘要: |
| 制备活性氧化铝负载铁、钴作为催化剂，并用XRD和SEM对该催化剂进行表征。考察了负载物初始浓度配比，Na2S2O8浓度，催化剂用量，苋菜红初始浓度，紫外光光照时间，pH值以及无机离子对降解苋菜红的影响。实验结果表明：当催化剂中的Fe：Co=1：2时，其降解能力最强。在苋菜红初始浓度为40 mg/L时，过硫酸钠浓度为1.5 g/L，催化剂用量为1.0 g/L，pH值为5，紫外光照射30 min的条件下，苋菜红的脱色率最高可达97.91%。且不同无机离子对反应体系有一定的抑制作用。 |
| 英文摘要: |
| Activated alumina loaded with iron and cobalt was prepared as a catalyst. The catalyst was characterized by XRD and SEM. The effects of the factors such as the proportion of loaded substances, the concentration of sodium persulfate, catalyst dosage, initial concentration of amaranth red, the time of UV irradiation, pH value and different inorganic ions on the degradation of amaranth red were investigated. The results showed that when the ratio of Fe-Co in the catalyst was 1:2, the degradation ability was strongest. When the initial concentration of amaranth red was 40 mg/L, the initial concentration of sodium persulfate was 1.5 g/L, catalyst dosage was 1.0 g, pH value was 5, and the time of UV irradiation was 30 minutes, the decolorization rate of amaranth red could reach 97.99%. And different inorganic ions had some inhibitory effects on the reaction system. |
