High-level arsenite removal from groundwater by zero-valent iron.
The objectives of this study were to conduct batch and column studies to (i) assess the effectiveness of zero-valent iron for arsenic remediation in groundwater, (ii) determine removal mechanisms of arsenic, and (iii) evaluate implications of these processes with regard to the stability of arsenic and long-term remedial performance of the permeable reactive barrier (PRB) technology. A high conc...
متن کاملLong-term Performance of Permeable Reactive Barriers Using Zero-valent Iron: An Evaluation at Two Sites
The permeable reactive barrier (PRB) technology is an in-situ approach for remediating groundwater contamination that combines subsurface fluid flow management with a passive chemical treatment zone. Removal of contaminants from a groundwater plume is achieved by altering chemical conditions in the plume as it moves through the reactive barrier. Because the reactive barrier approach is a passiv...
متن کاملLong-Term Performance of Zero-Valent Iron Permeable Reactive Barriers: A Critical Review
Permeable reactive barriers (PRBs) have shown great promise as an alternative to pump and treat for the remediation of groundwater containing a wide array of contaminants including organics, metals, and radionuclides. Analyses to date have focused on individual case studies, rather than considering broad performance issues. In response to this need, this study analyzed data from field installat...
متن کاملRemoval of Acid Red 18 dye from Aqueous Solutions Using Nanoscale Zero-Valent Iron
Background and Purpose:Organic dyes with a complex structure are often toxic, carcinogenic, mutagenic, non-biodegradation and stable in the environment and if released to the environment without treatment can endanger the environment and human health. The aim was to evaluate the performance nanoscalezero-valent iron (NZVI) in the removal of dye acid red 18 (AR18) from aqueous solutions. Materia...
متن کاملmodeling nitrate removal by nano-scaled zero-valent iron using response surface methodology
background contamination of water resources with nitrate is a serious environmental problem in many regions of the world. in addition, this problem has been observed in some regions of iran. as nitrate is threatening for human health and environment, it must be decreased to standard levels in drinking water. objectives the purpose of this research was to model the nitrate removal from water by ...
