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 CO23- 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. © 2023 Science Press. All rights reserved.
