    Ultrasonic-assisted hydrogen peroxide leaching of cadmium-containing flue dust under room temperature and neutral conditions: Efficient recovery and mechanism by Yuxi Xie, Tian Wang, Yuanru Wang, Yan Gao, Shihao Liu, Fei Niu, Phan Duc Lenh, Thiquynhxuan Le, Libo Zhang

    Published 2025-09-01
    “…Mechanistic studies indicate that ultrasound inhibits particle agglomeration, disrupts encapsulated structures, and generates hydroxyl radicals, enhancing oxidation of cadmium and lead-containing phases for efficient separation. Kinetic studies reveal that the introduction of ultrasound reduces the activation energy from 16.198 to 3.389 kJ·mol−1, changing the rate-determining step from a mixed control to diffusion control, thereby accelerating leaching kinetics. …”
