Catalytic reductive dechlorination of p-chlorophenol in water using Ni/Fe nanoscale particles.

Reductive dechlorination of p-chlorophenol by nanoscale iron.

OBJECTIVE To investigate reductive dechlorination of 4-chlorophenol (4-CP) by nanoscale Fe0 under different conditions. METHODS Nanoscale Fe0 was synthesized by using reductive method. 4-CP and its intermediate products were analyzed by HPLC. Chlorine ion was quantified with DX-100 ion chromatograph. Nano-iron particles were observed under a FEI Quanta 200 FEG environmental scanning electron ...

Nanoscale Pd/Fe bimetallic particles: Catalytic effects of palladium on hydrodechlorination

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...

TCE dechlorination rates, pathways, and efficiency of nanoscale iron particles with different properties.

Nanoscale Fe0 particles are a promising technology for in situ remediation of trichloroethene (TCE) plumes and TCE-DNAPL source areas, butthe physical and chemical properties controlling their reactivity are not yet understood. Here, the TCE reaction rates, pathways, and efficiency of two nanoscale Fe0 particles are measured in batch reactors: particles synthesized from sodium borohydride reduc...

Simple colorimetric assay for dehalogenation reactivity of nanoscale zero-valent iron using 4-chlorophenol

Despite the wide application of nanoscale zero valent iron (nZVI) for the treatment of a plethora of pollutants through reductive reactions, reactivity evaluation of nZVI towards dehalogenation has not been standardized. In this light, it was desired to develop a simple colorimetric assay, for versatile laboratory application, using merely a spectrophotometer for color intensity determination. ...
