This research reported a new method of removal of Pb+2from water by using a nano zero valent iron (nZVI) assisted ultrasonic wave. At first, nZVI was synthesized by an ultrasound assisted method. Particles morphology and surface composition were characterized by FESEM, XRD, and EDX. The XRD patterns showed that the crystallinity of the nZVI prepared using ultrasonic conditions was hi...

A new method for the synthesis of nano zero-valent iron (nZVI) was developed in the present study. Ultrasonic waves, as a novel method, were used to synthesize the nanoparticles. The morphology and surface compositions of the particles were characterized by using FESEM, XRD, BET, and particle size analyzer. The synthesized nanoparticles were then utilized as a Fenton-like catalyst to degrade of...

This study proposed a sequential redox process to partially degrade tetrabromobisphenol A (TBBPA) within reactor great extent. After 72 hours in an anoxic environment, 20 ppm of TBBPA could be effectively degraded by sulfurized zerovalent iron nanoparticles (S-nZVI) at concentrations 2 g L-1 and 4 L-1. Biphenol (BPA) together with tri-, di-, monobromobisphenol was detected high-performance liqu...

The subsurface injection of nanoscale zero-valent iron particles (nZVI) for the in situ reductive remediation contaminated aquifers has grown over last 25 years. However, several efforts are still being made to improve stability and delivery nZVI simplify procedure site-specific design. In this study, injectability mobility a commercial nZVI-based reactive gel was tested radial geometry laborat...

hexavalent chromium is mobile and hazardous in the environment. electrokinetic remediationof chromium (iv)-contaminated soils is intended either to remove or to reduce cr (vi) to cr (iii). this studyexamines the effectiveness of utilizing edta and acetic acid solutions as alternative electrolytes in theelectrokinetic (ek) process, with coupled nano-scale zero-valent iron (nzvi) as a barrier for...

Abstract Biochar (BC) has gained attention for removal of toxic elements (TEs) from aqueous media; however, pristine biochar often exhibits low adsorption capability. Thus, various modification strategies in BC have been developed to improve its capability against TEs. Nanoscale zero-valent iron (nZVI) and oxides (FeOx) used as sorbents TE removal. However, these materials are prone agglomerati...

Nanozero-valent iron (NZVI) shows great potential in the remediation of water pollution, but its application is limited by instability and tendency to aggregate. To enhance dispersibility antioxidant properties NZVI, we prepared composites (SN) wrapping NZVI with sodium alginate (SA) for removal Pb(II) from water. Various characterization methods such as SEM-EDS, BET, XPS, FT-IR were used study...

Nanoscale zero-value iron (nZVI) has a high specific surface area and significant abilities to reduce contaminants. In this study, the removal of color COD from real textile wastewater was studied by nZVI particles. A series experiments were conducted evaluate effect operational parameters such as solution pH, dosage temperature on removal. The results showed that removals mainly depend pH. eff...
