| 中文摘要 |
| 通过搭建超声复合铁碳活化过硫酸盐耦合系统（US/PS/Fe-C），用于处理三苯甲烷衍生物结晶紫（CV）.结果表明US/PS/Fe-C三元体系具有良好的耦合效果.对商品铁碳和自制的不同工艺铁碳活化剂，分别采用X-射线衍射仪和扫描电子显微镜对活化剂的结构和表面形貌进行分析.使用商品铁碳作为活化剂研究不同因素对US/PS/Fe-C三元耦合体系降解CV的影响，其最优条件为：PDS浓度2 mmol ·L-1，铁碳活化剂1 g ·L-1，pH未调，30 min后对质量浓度为15 mg ·L-1CV的去除率达90%.探究阴阳离子对于体系的影响，发现Mg2+和NO3-对体系处理几乎没有影响，Mn2+、Cl-和CO32-对于体系的处理有一定的抑制作用，Fe2+在低浓度时可以促进反应，在高浓度时会抑制反应.通过加入不同的淬灭剂，得出在该体系中主要含有1O2、SO4- ·、·O2-和·OH这4种活性物质. |
| 英文摘要 |
| A coupling system of ultrasonic composite iron-carbon activated persulfate (US/PS/Fe-C) was built to treat a triphenylmethane derivative, crystal violet (CV). The results revealed that US/PS/Fe-C ternary system had a good coupling effect. The structure and surface morphology of commercial Fe-C and self-made Fe-C catalysts were analyzed using an X-ray diffractometer (XRD) and scanning electron microscope (SEM), respectively. Finally, commercial Fe-C was used to study the effects of different factors on the CV of US/PS/Fe-C ternary coupling degradation, and the optimum conditions were as follows:PDS concentration 2 mmol·L-1, iron-carbon catalyst 1 g·L-1, pH without adjustment, and the removal rate of 15 mg·L-1 CV reached 90% after 30 min. To explore the effects of anions and cations on the system, it was observed that Mg2+ and NO3- had almost no effect on the treatment of the system, and Mn2+, Cl-, and CO32- had a certain effect on the treatment of the system, whereas Fe2+ could promote the reaction at low concentration and inhibit the reaction at high concentration. By adding different quenchants, it was concluded that there were four types of active substances:1O2, SO4-·,·O2-, and·OH. |
