modeling 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 ...
متن کاملNitrate reduction using zero-valent iron and effect of corrosion inhibitor on reduction
---------------------------------------------------------------------***--------------------------------------------------------------------Abstract The objective of this work is to study reduction of nitrate concentration using zero-valent iron (ZVI) which has its application in permeable reactive barriers (PRBs). Also, to find out effect of concrete penetrating corrosion inhibiting admixture ...
متن کاملChemical Reduction of Hexavalent Chromium (VI) in Soil Slurry by Nano Zero Valent Iron
The increasing industrial development of recent decades has lead to the production of increasing quantities of waste containing heavy metals, elements often harmful to the environment, which in the past were not properly disposed of, thus inducing soil and groundwater pollution. In particular, chromium (Cr) and its derivatives are largely used in industries such as textiles, electronics, metall...
متن کاملChromium Reduction by Zero-valent Iron and Bacteria
A study of alternative chromium reduction methods was performed for wastewater or contaminated water. Two existing chromium reduction treatment methods were tested on the wastewater samples: treatment with (1) zero-valent iron, and (2) bacteria cultures. We found that both methods can reduce chrome. However, the chrome reduction process using bacteria is considerably slower than that using iron...
متن کاملElectrochemical depassivation of zero-valent iron for trichloroethene reduction.
Permeable reactive barriers (PRBs) composed of zero-valent iron (ZVI) are susceptible to passivation, resulting in substantially decreased rates of chlorinated solvent removal over time. In this study, the application of low electrical direct current (DC) to restore the reductive capacity of passivated ZVI was examined. Electrical current was applied to a laboratory column reactor filled with a...
