MOF-derived carbon-based materials have attracted widespread attention due to their relatively large surface area, morphology, and stability in water. Considering these advantages, present themselves as excellent adsorbents. In this work, a novel method was designed for the fabrication of nano zero-valent-iron (nZVI) carbon composite. The utilization zinc oxide nanorods (ZnONRs) role sacrificia...

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...

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 th...

The potential of iron nanoparticles as adsorbents for water remediation has not been fully exploited because their intrinsically low stability. Herein, few-layered graphene-encapsulated ([email protected]0) supported on and within lignin-derived carbon were synthesized via an in-situ thermal conversion ferric nitrate-loaded kraft lignin, i.e., nitrate a Fe source lignin source. structure morpho...

background: in this research, the decomposition of aroclor 1254, including 20 kinds of poly chlorinated biphenyls (pcbs), in real waste transformer oil in the presence of peg1000, naoh, zero valent iron and h2o by microwave (mw) irradiation was studied. methods: central composites design (ccd) method was carried out for experimental design. the effects of microwave power levels (200- 1000 w), r...
