Multi-chamber membrane capacitive deionization coupled with peroxymonosulfate to achieve simultaneous removal of tetracycline and peroxymonosulfate reaction byproducts

Journal of Hazardous Materials
Advanced oxidation technologies based on peroxymonosulfate (PMS) have been extensively applied for the degradation of antibiotics. However, the degradation process inevitably introduces SO42- and other sulfur-containing anions, these pollutants pose a huge threat to the water and soil environment.

Effect of mixing on peroxymonosulfate generation

2009
Efficient generation of pulping and bleaching chemicals is essential to economic production of pulp. In some cases the success of a proposed process will depend on whether the key chemical can be generated economically at an industrial scale. Peroxymonosulfate (PMS, Na₂S0₅) has shown to be an effective and selective TCF bleaching agent for both ...

Degradation of Uv328 by Ozone/Peroxymonosulfate System: Performance and Mechanisms

Chemosphere
2-(2H-benzotriazol-2-yl)-4,6-di-tert-pentylphenol (UV328) is an emerging persistent organic pollutant ubiquitously found in environmental matrices. Though some advanced oxidation processes have been tested to degrade UV328 in waste streams, the degradation mechanisms are largely unknown.

Peroxymonosulfate activation by phosphate anion for organics degradation in water

Chemosphere, 2014
Activation of peroxygens is a critical method to generate oxidative species, but often consumes additional chemical reagents and/or energy. Here we report a novel and efficient activation reaction for peroxymonosulfate (PMS) by phosphate anions (PBS). The PBS/PMS coupled system, at neutral pH, is able to decompose efficiently even mineralize a variety ...

Oxidation of alkyl sulfides by aqueous peroxymonosulfate

Environmental Science & Technology, 1992
The kinetics and mechanism of the oxidation of the alkyl sulfides dimethyl sulfide (DMS) and diethyl sulfide (DES) by peroxymonosulfate (HSO 5 - ) in aqueous solution were studied as a function of pH, temperature, and ionic ...

Activation of Peroxymonosulfate by Benzoquinone: A Novel Nonradical Oxidation Process

Environmental Science & Technology, 2015
The reactions between peroxymonosulfate (PMS) and quinones were investigated for the first time in this work, where benzoquinone (BQ) was selected as a model quinone. It was demonstrated that BQ could efficiently activate PMS for the degradation of sulfamethoxazole (SMX; a frequently detected antibiotic in the environments), and the degradation rate ...

Reactivity and reaction pathways of peroxymonosulfate and peroxydisulfate with neonicotinoid insecticides

Water Research
Neonicotinoid insecticides (NNIs), which have been detected across diverse aquatic environments, have sparked substantial concerns regarding their potential adverse ecological and health risks. In this study, the removal of NNIs by unactivated peroxymonosulfate (PMS) and peroxydisulfate (PDS) was systematically investigated. Results showed that PMS/PDS

Bromide triggers efficient peroxymonosulfate activation for phosphonate degradation

Environmental Science and Pollution Research
Phosphonates have received a widespread attention in wastewater treatment due to their potential threat to the water environment. Advanced oxidation processes (AOPs) are feasible methods to degrade phosphonates, and most of the coexisting substances in water show a negative factor during their oxidation.
