Ultrasound assisted zero valent iron corrosion for peroxymonosulfate activation for Rhodamine-B degradation.
Chemosphere. 2019 Aug; 228:412-417.C

Abstract

In this work, ultrasound (US) irradiation assisted powder zero valent iron (ZVI) corrosion was conducted for peroxymonosulfate (PMS) activation. PMS activation activity was evaluated by Rhodamine-B (Rh B) degradation efficiency. The other US/PMS, ZVI/PMS, Fe2+/PMS and US/PMS/Fe2+ systems were performed to investigate the synergistic effects of US and ZVI on PMS activation activity. US/PMS/ZVI system performed the highest activity of Rh B degradation. 99.76% of Rh B was removed within 12 min under the optimum condition (pH = 4.5, ZVI dosage = 1 g/L, PMS = 1 mM, US power = 50 W). A comparison of US/PMS/ZVI system with PMS/ZVI and homogeneous US/PMS/Fe2+ systems for Rh B degradation was conducted, indicating that ultrasound irradiation contributed to acceleration of ZVI corrosion and removal of passive films. Besides, the electrons transformation from Fe0 to PMS made main contribution to the generation of sulfate radical, which resulted in the ability of degradation of Rh B. ZVI could be reused for five cycles with efficient activity of PMS activation. Exhaustion of ZVI led to the decrease in PMS activation at the sixth recycle. Thus, this work presents important information on understanding reuse of iron fillings for PMS/PS activation in practical application of pollution remediation.
