Dennis G. Brown* and W. Leo Johnson, III Department of Chemistry University of Idaho Moscow, Idaho, U. S. A. Z. Naturforsch. 34b, 712-715 (1979); received January 9, 1979 Semiquinone, Iron, Chromium Tris o-benzosemiquinone complexes of iron and chromium are reported. These complexes contain three 3,5-di-£-butyl-o-semiquinato ligands and a tri valent metal ion. The iron complex can be obtained f...

Elevated nitrate concentrations in groundwater and surface water supplies can negatively impact the quality of environment human health. Recent studies have examined use zero-valent iron technology to treat nitrate-contaminated groundwater. Mechanistic aspects reduction by are unresolved. This project investigated kinetics mechanism under anoxic conditions oxic conditions. Stirred-batch reactio...

Zero-valent iron nanoparticles rapidly aggregate. One of the reasons is magnetic forces among the nanoparticles. Magnetic field around particles is caused by composition of the particles. Their core is formed from zero-valent iron, and shell is a layer of magnetite. The magnetic forces contribute to attractive forces among the nanoparticles and that leads to increasing of aggregation of the nan...

Reported herein is a study on the catalytic properties of palladium for hydrodechlorination using nanoscale zero-valent iron particles. Temperature-dependent experiments and X-ray diffraction (XRD) are conducted to characterize reactions of chlorinated ethylenes with nanoscale Fe and Pd/Fe particles. XRD results suggest bimetallic structures are created as a result of Pd(II) reduction by zero-v...

The in situ synthesis of air-stable zero-valent iron nanoparticles (NZVI) embedded in cellulose fibers leads to the assembly of highly reactive magnetic filter papers. These engineered materials display a wide range of applications in the treatment of wastewater and drinking water, including chromium removal, phenol degradation, environmental bioremediation, and catalysis.

leachate treatment from municipal landfills has been always a major anxiety in waste management due to its high level of various contaminations. in this paper the effect of nanosized zero valent iron particles (nzvi) in fenton process for the treatment of high cod strength landfill leachate was scrutinized. the results corroborated this procedure was fast and efficient. in fact, about 87% of in...

recently, a variety of soils contaminated with heavy metals e.g. cr (vi), have been found in industrial sites. such soil contamination is widely distributed in the world and has now become a serious issue for environment. hexavalent chromium, cr (vi), which is known to be carcinogenic and mutagenic to living organisms, has been utilized for leather tanning, electroplating and in other industrie...
