Application of synthesized nanoscale zero-valent iron in the treatment of dye solution containing Basic Yellow 28
Nanoscale zero-valent iron NZVI particles were synthesized by the aqueous phase borohydride reduction method, and the synthesized NZVI particles were used for the degradation of Basic Yellow 28 BY28 dye in aqueous solution. The influence of experimental variables such as reaction time, NZVI particle dosage and pH were studied on the decolorization of BY28. Mixing an aqueous solution of 100 mg L...
متن کاملApplication of nanoscale zero valent iron (NZVI) for groundwater remediation in Europe.
PURPOSE Nanoscale zero valent iron (NZVI) is emerging as a new option for the treatment of contaminated soil and groundwater targeting mainly chlorinated organic contaminants (e.g., solvents, pesticides) and inorganic anions or metals. The purpose of this article is to give a short overview of the practical experience with NZVI applications in Europe and to present a comparison to the situation...
متن کاملUse of nanoscale zero-valent iron to improve the shear strength parameters of gas oil contaminated clay
In recent years, the nanoscale zero-valent iron (NZVI) particles have been used successfully for the degradation of hydrocarboncompounds and remediation of other pollutants. Nevertheless, as far as we know, there is no specific study on the improvement of thegeotechnical properties of contaminated soils with hydrocarbon compounds by NZVI. This study used NZVI particles to remove gasoil in a cla...
متن کاملEvaluation on the Nanoscale Zero Valent Iron Based Microbial Denitrification for Nitrate Removal from Groundwater
Nanoscale zero valent iron (NZVI) based microbial denitrification has been demonstrated to be a promising technology for nitrate removal from groundwater. In this work, a mathematical model is developed to evaluate the performance of this new technology and to provide insights into the chemical and microbial interactions in the system in terms of nitrate reduction, ammonium accumulation and hyd...
متن کاملInfluence of nanoscale zero-valent iron on geochemical properties of groundwater and vinyl chloride degradation: A field case study.
A 200m(2) pilot-scale field test successfully demonstrated the use of nanoscale zero-valent iron (NZVI) for effective remediation of groundwater contaminated with chlorinated organic compounds in Taiwan within six months. Both commercially available and on-site synthesized NZVI were used. A well-defined monitoring program allowing to collect three-dimensional spatial data from 13 nested multi-l...
