J Hazard Mater 2019 Feb 13;369:448-455. Epub 2019 Feb 13.

School of Environmental Science and Spatial Informatics, China University of Mining and Technology, Xuzhou 221008, Jiangsu Province, China.

This work investigated the influences of citric acid and methyl-β-cyclodextrin (MCD) as enhancing agents during the electrokinetics (EK)-persulfate process on the remediation of soil artificially contaminated with decabromodiphenyl ether (BDE-209) and copper (Cu) with an initial concentration of 50 and 1000 mg/kg, respectively. The results clearly demonstrate the efficiency of the process while at the same time, the distribution of the residual contaminants in soil and the EK parameters were greatly influenced by the presence of persulfate, MCD and citric acid. The results show that there was significant removal of BDE-209 and Cu from the soil. Read More

Kinetics study on non-thermal plasma mineralization of adsorbed toluene over γ-Al2O3 hybrid with zeolite.

J Hazard Mater 2019 Jan 30;369:430-438. Epub 2019 Jan 30.

School of Environment & Municipal Engineering, Xi'an University of Architecture & Technology, Xi'an, 710055, China.

Non-thermal plasma mineralization of the adsorbed toluene over γ-AlO hybrid with 13X, ZSM-5, and HY was investigated in a sequential adsorption and plasma oxidation system. The γ-AlO-13X was shown to have a better plasma oxidation performance with fewer by-products as compared to γ-AlO-ZSM-5 and γ-AlO-HY, which was due to its better discharge performance and O decomposition ability. For all of the tested materials, the plasma mineralization of the adsorbed toluene process had a good match with the pseudo-second-order kinetic model: kt = 1/n - 1/n, where n and n are the amount of adsorbed toluene (mmol) at discharge time = 0 and t, respectively.

Efficient bacteria inactivation by ligand-induced continuous generation of hydroxyl radicals in Fenton-like reaction.

J Hazard Mater 2019 Feb 12;369:408-415. Epub 2019 Feb 12.

State Key Laboratory of Chemical Resource Engineering, Beijing University of Chemical Technology, Beijing, 100029, China. Electronic address:

Fenton/Fenton-like reaction is often used as an efficient method to generate hydroxyl radicals (HO) for bacteria inactivation in aqueous solution. However, inactivation efficiency of bacteria in aqueous solution using Fenton/Fenton-like reactions needs to further improve as a result of transient generation of HO. In this paper, we found that the formation of Tris-Co(II) complexes could decrease the redox potential of Co(III)/Co(II), facilitating the transformation of Tris-Co(III) complexes into Tris-Co(II) complexes.

Effects of backwashing strategy and dissolved oxygen on arsenic removal to meet drinking water standards in a sulfidogenic attached growth reactor.

J Hazard Mater 2019 Feb 8;369:309-317. Epub 2019 Feb 8.

Department of Civil Engineering, IIT Guwahati, Guwahati, India. Electronic address:

Efficiency and feasibility of two backwashing methods (water-nitrogen and water-air assisted) on arsenic and its co-pollutants removal were assessed through running a sulfidogenic attached growth reactor (AGR) treating arsenic spiked simulated groundwater for about 600 days. Replacing water with nitrogen assisted backwashing (WNAB) by water with air assisted backwashing (WAAB) introduced dissolved oxygen (DO) as an additional electron acceptor, which required an increased empty bed contact time (EBCT) to retain the entire terminal electron accepting zones (DO, nitrate, arsenate and sulfate) within the reactor. Removal of arsenic to below 10 μg/L required a longer EBCT at higher influent DO in backwash water. Read More

Photosensitized diastereoisomer-specific degradation of hexabromocyclododecane (HBCD) in the presence of humic acid in aquatic systems.

J Hazard Mater 2019 Feb 11;369:171-179. Epub 2019 Feb 11.

Division of Environmental Science and Engineering, Pohang University of Science and Technology (POSTECH), Pohang, 37673, Republic of Korea. Electronic address:

Humic acids (HA) are the most important photosensitizers in the ocean and generate highly reactive oxygen species (ROS), known as photochemically produce reactive intermediates (PPRI), which degrade organic pollutants. Thus, to reveal the fate of organic pollutants in an aqueous environment, it is important to understand the natural photodegradation phenomenon caused by HA. Three ROS generated from HA, O, O-, and OH, were measured using different probe compounds and instrumental techniques. Read More

Department of Building, Civil and Environmental Engineering, Concordia University, 1445 de Maisonneuve Blvd. West, Montreal, QC H3G 1M8, Canada.

The interaction of multiple pool fires might lead to higher burning rate and flame height than single pool fire, raising the possibility of fire ignition and flame spread and increasing the risks to people, buildings and environment. To quantify the burning rate and flame height of multiple pool fires from the view of physical mechanism, this paper presents an experimental study on two identical square pool fires.

The State Key Laboratory of Explosion Science and Technology, Beijing Institute of Technology, Beijing, 100081, China.

To facilitate the pre-estimation and optimization of the prescription design of a multi-component polymer bonded explosive (PBX), a multicomponent mesoscopic reaction rate model (MC-DZK model) is developed to predicate preferably the influence of both the explosive components and the particle size of on the shock initiation. All the parameters in the model are determined directly by the parameters in the DZK model for each explosive component. Furthermore, for the multicomponent insensitive explosive PBXC10 (70% TATB, 25% HMX, and 5% Kel-F800 by weight) with different explosive particle sizes, both shock initiation experiments and corresponding numerical simulations are performed, and there is satisfactory agreement between the numerical results and the available experimental data.

All kinds of wastewaters containing steroid estrogens (SEs) and mixed endogenous source dissolved organic matter (DOM) enter natural water environments with intermittent illumination where microbial action occurs in a relatively deep natural aqueous environment. The role of mixed endogenous source DOM in SEs' biodegradation and photochemical degradation in such environments was studied using 17β-estradiol (E2) in laboratory experiments under anaerobic conditions. The experimental results show that microbial action can improve the optical properties and electron transfer capability of mixed endogenous source DOM, promoting photodegradation and biodegradation.
