In order to study the effect of zero-valent iron nanoparticles on morphological and physiological traits of canola (Brassica napus L. cv. 'Hayola 401') under salinity stress, a research was conducted under controlled conditions in factorial based on completely randomized design in three replicates. In the first phase, the zero-valent iron nanoparticles were synthesized and in the second phase, ...
volatile organic compounds (vocs) are in categories of mankind and environmentally harmful materials. some of vocs are also carcinogenic and mutagen. because of expanded application of these compounds as various domestic and industrial usages, prevention of environmental contamination of these compounds is a substantial issue. in this study, the effect of zero-valent iron nanoparticles applica...
Magnetic nanomaterials are making significant impact on improving the quality of human health that is tangible from a wide range of applications in various fields of medicine and biology. In recent years, nanoparticles successfully demonstrated outstanding applications due to having excellent magnetic properties of the iron oxide nanoparticles-based counterparts. Zero-valent iron nanoparticles ...
In the present work, nano scaled zero valent irons (nZVI) were synthesized in ethanol medium by the method of ferric iron reduction using sodium borohydride as a reducing agent under atmospheric conditions. The obtained iron nanoparticles are mainly in zero valent oxidation state and remain without significant oxidation for weeks. A systematic characterization of nZVI was performed using UV, XR...
manganese is one of the significant raw materials for various industries and most difficult element to remove from water because of its high solubility. the treatment of mn (ii) contained wastewater is stringent for environmental preservations. in the present study adsorption of mn2+ on zero-valent iron nanoparticles synthesized by chemical reduction process and modified with phosphate coating ...
conclusions briefly, the current study represents a novel method to eliminate temephos as an organophosphate compound from water samples with modified zero-valent iron nanoparticles. background temephos is an organophosphate pesticide used as larvicide in the environment. although not extremely hazardous, it can be risky for human health in the moderate concentrations. objectives this study inv...
Zero-valent iron nanoparticles are used for the degradation of organic compounds and the immobilization of metals and metalloids. The lack of information on the effect of nZVI in freshwater system necessitated the risk assessment of zero-valent iron nanoparticles in lake water environment. The present study deals with the stability and fate of synthesized zero-valent iron nanoparticles in the u...
The microbiological impact of zero-valent iron used in the remediation of groundwater was investigated by exposing a trichloroethylene-degrading anaerobic microbial community to two types of iron nanoparticles. Changes in total bacterial and archaeal population numbers were analyzed using qPCR and were compared to results from a blank and negative control to assess for microbial toxicity. Addit...
nowdays, iron nanoparticles due to their unique characteristics are used in all of sciences and technology. these nano particles due to their electrical, magnetic, optical and catalytic properties and having high area and activity that is promped by their small size and most importantly many scientists from the entire world are interested in their ...
Background & Aims of the Study: The heterotrophic bacteria are widely used as a water microbial pollution index for drinking water. The aim of this study was to investigate the effect of metallic nanoparticles such as Zero Valent Iron (ZVI), Titanium dioxide (TiO2) and Zinc oxide (ZnO) on Heterotrophic Bacter...
