Plant enhanced degradation of phenanthrene in the contaminated soil

引用

Journal of Environmental Sciences 2006年第3期18卷 510-513页

作者： liao Min XIE Xiao-mei School of Environmental and Resources Sciences Zhejiang University Hangzhou 310029 China

The degradative characteristics ofphenanthrene, microbial biomass carbon, plate counts ofheterotrophic bacteria and most probable number （MPN） of phenanthrene degraders in non-rhizosphere or rhizosphere soils with uninoculating or inoculating phenanthrene degraders were measured. At the initial concentration of 20 mg phenanthrene/kg soil, the half-lives of phenanthrene in uninoculated non-rhizosphere soil, uninoculated rhizosphere soil, inoculated non-rhizosphere soil, and inoculated rhizosphere soil were measured to be 81.5, 47.8, 15.1 and 6.4 d, respectively, and corresponding kinetic data fitted first-order kinetics. The highest degradation rate of phenanthrene was observed in inoculated rhizosphere soil. The degradative characteristics of phenanthrene were closely related to the effects of vegetation on soil microbial process. Vegetation could enhance the magnitude of rhizosphere microbial communities, microbial biomass content, and heterotrophic bacterial community, but barely influence those community components responsible for phenanthrene degradation. Results suggested that combination of vegetation and inoculation with degrading microorganisms of target organic contaminants was a better pathway to enhance degradation of the organic contaminants in soil.

Two-dimensional metal oxide nanosheets for rechargeable batteries

引用

Journal of Energy Chemistry 2018年第1期27卷 117-127页

作者： Jun mei Ting liao Ziqi Sun School of Chemistry Physics and Mechanical EngineeringQueensland University of Technology2 George StreetBrisbane.OLD 4000Australia

Two-dimensional（2D） metal oxide nanosheets have attracted much attention as potential electrode materials for rechargeable batteries in recent years. This is primarily due to their natural abundance, environmental compatibility, and low cost as well as good electrochemical properties. Despite the fact that most metal oxides possess low conductivity, the introduction of some conductive heterogeneous components, such as nano-carbon, carbon nanotubes（CNTs）, and graphene, to form metal oxide-based hybrids,can effectively overcome this drawback. In this mini review, we will summarize the recent advances of three typical 2D metal oxide nanomaterials, namely, binary metal oxides, ternary metal oxides, and hybrid metal oxides, which are used for the electrochemical applications of next-generation rechargeable batteries, mainly for lithium-ion batteries（LIBs） and sodium-ion batteries（SIBs）. Hence, this review intends to functionalize as a good reference for the further research on 2D nanomaterials and the further development of energy-storage devices.

Adsorption of Metsulfuron and Bensulfuron on a Cationic Surfactant-Modified Paddy Soil

引用

Pedosphere 2007年第1期17卷 101-108页

作者： liao Min XIE Xiao-mei College of Environmental and Resource Sciences Department of Resources Science Zhejiang University Hangzhou 310029 （China）

Adsorption isotherms of metsulfuron and bensulfuron on a hexadecyltrimethylammonium （HDTMA） bromide-modified paddy soil under different ionic strengths, with divalent cation Cu^2＋, or having different pH were studied to describe their adsorptive behavior, and to try to explain the adsorption process of a sulfonylurea compound with a carbamoylsulfamoyl group in the modified soil environment. All the adsorption isotherms fitted the Freundlich equation well, and the HDTMA treatment of paddy soil dramatically enhanced adsorption capacity of metsulfuron or bensulfuron. Also, an increase of ionic strength and the addition of divalent heavy metal cation Cu^2＋ on the HDTMA-modified paddy soil increased the adsorption of metsulfuron or bensulfuron. Additionally, for metsulfuron and bensulfuron in the aqueous phase, adsorption capacity of the HDTMA-modified paddy soft gradually increased with decreasing pH.
