Abstract
Sulfate radical advance oxidation processes (SR-AOPs) have attracted a greater attention as a suitable alternative of the hydroxyl radical based advance oxidation process (HR-AOPs). In this study, for the first time we report liquid phase mineralization of nuclear grade cationic IRN-77 resin in Co2+/peroxymonosulfate (PMS) based SR-AOPs. After the dissolution of cationic IRN-77 resin, 30 volatile and 15 semi-volatile organic compounds were analyzed/detected using non-targeted GC-MS analysis. The optimal reaction parameters for the highest chemical oxygen demand (COD) removal (%) of IRN-77 resin were determined, and the initial pH, PMS dosage, and reaction temperature were found to be the most influential parameters for the resin degradation. We successfully achieved ∼90% COD removal (1000 mg/L; 1000 ppm) of dissolved spent resin for SR-AOPs by optimizing the reaction parameters as initial pH = 9, Co2+ = 4 mM (catalyst), PMS = 60 mM (as oxidant) at 60 °C temperature for 60 min reaction. The electron spin resonance spectroscopy (ESR) spectra confirmed the presence of SO4∙- and OH∙ as main reactive species in the Co2+/PMS resin system. In addition, Fourier transform infrared spectroscopy (FT-IR) analyses were used for structural characterization of solid and liquid phase resin samples. We believe that this work will offer a robust approach for the effective treatment of spent resin generated from nuclear industry.

Abstract
The treated mixed-crystal TiO(2) powder with high sonocatalytic activity was obtained through utilizing ultrasonic irradiation in hydrogen peroxide solution. At the same time, some influencing factors (including heat-treated temperature and heat-treated time) on the sonocatalytic activity of treated mixed-crystal TiO(2) powder were also considered through the degradation of methylene blue in aqueous solution. In this work, it was found that the sonocatalytic degradation ratio of methylene blue in the presence of treated mixed-crystal TiO(2) powder was much higher than ones in the presence of nano-sized rutile phase TiO(2) powder and with onefold ultrasonic irradiation. At last, the methylene blue in aqueous solution was completely degraded and became some simple inorganic anions such as NO(3)(-), SO(4)(2-) and Cl(-). All experiments indicated that the sonocatalytic method adopting treated mixed-crystal TiO(2) powder as sonocatalyst was an advisable choice for the treatments of non- or low-transparent wastewaters in future.
