In this study, a higher surface area spherical nanoscale zero valent iron (HNZVI) cluster (80 nm, 54.25 m(2)g(-1)) was synthesized in ethanol-water mixed solvent in the presence of dispersion agent of polyglycol (PEG). At the same time, a lower surface area nanoscale zero valent iron (LNZVI) particle (80 nm, 8.08 m(2)g(-1)) was also prepared with only(More)
Nano-scale zero-valent iron particles (NZVI) are increasingly being used to treat sites contaminated with chlorinated solvents. This study investigated the effect of NZVI on dechlorinating microorganisms that participate in the anaerobic bioremediation of such sites. NZVI can have a biostimulatory effect associated with water-derived cathodic H(2)(More)
A trichloroethylene (TCE) dechlorinating enrichment (Dehalococcoides spp.), which was isolated from soil of chlorinated ethene contaminated site, was used to investigate whether nano-scale zero valent iron (NZVI) could serve as electron donor for this consortium via cathodic H2 production during anaerobic corrosion. The results show that in the presence of(More)
In addition to the less active metallic nickel, a new strategy was employed to enhance the activity of nano-Fe0 for the nitrate reduction. A novel carbon material called expanded graphite was employed to act as the support of bimetallic Ni/Fe. Through a synthesis procedure that includes consecutive steps of an incipient wetness impregnation method, heat(More)
The robust stabilization of a class of nonlinear systems with bounded parametric uncertainties is considered. Firstly, based on Lyapunov stability theory, the state feedback controller is obtained when the nominal system is minimum-phase. Secondly, on the basis of above control law, we construct a closing-loop robust controller to attenuate the error(More)
Nanoscale alpha-Fe particles with size of about 80 nm were prepared with a microemulsion-coated method. The results demonstrated that this kind of iron particles could exist stably in the air for 7 d compared with nanoscale iron particles prepared by liquid-phase and microemulsion methods. The removal rate of trichloroethylene with an initial concentration(More)
Seventeen strains with wideranging decolorization ability were screened from contaminated soil and were applied on the decoloring of dye wastewater. Three strains were selected due to their high decolorization capacity on azo dyes, anthraquinone dyes and triphenylmethane dyes. The three strains were named as Strain I, Strain II, Strain III. This three(More)
Biomass solid wastes containing lignocelluloses become more than 1 billion tons in China, 2010. If biomass solid wastes can be degraded into fertilizer, it would greatly promoted economic and social improvement. On the basis of experiments, aeration, moisture content, particle size, fermentation temperature and pH were the main factors affecting mixing(More)
