Abstract Nanoscale zero-valent iron-doped carbonized zeolitic imidazolate framework-8 (nZVI/CZIF-8) was prepared by carbonation of ferric nitrate and ZIF-8 at 800 °C used as an adsorbent to remove methylene blue (MB) from water. The synthesized nZVI/CZIF-8 has a specific surface area 806.9 m2/g, pore volume 0.86 cm 3 /g nZVI content 1.35%, respectively. Both the CZIF-8 have identical functional...

Nanoscale zero-valent iron (nZVI) has become a new and ecofriendly adsorbent material with promising applications. Herein, hydrotalcite-supported nanoscale (nZVI@H) is synthesized for the first time used testing removal of methylene blue (MB) in an aqueous solution. The successful fabrication nZVI@H characterized by SEM, BET, XRD, FTIR zeta-potential analyses. results showed that 99.6% MB remov...

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...

Nanoscale zero-valent iron NZVI particles were synthesized by the aqueous phase borohydride reduction method, and the synthesized NZVI particles were used for the degradation of Basic Yellow 28 BY28 dye in aqueous solution. The influence of experimental variables such as reaction time, NZVI particle dosage and pH were studied on the decolorization of BY28. Mixing an aqueous solution of 100 mg L...

The increasing production and broad application of engineered nanoparticles (ENPs) have led to a substantial release ENPs into natural systems. Despite their different utilization prospects, such as nanoscale zero-valent iron (NZVI) silver (AgNPs) been co-found in aquatic environments. This study comprehensively examined the effect AgNPs on reductive ability NZVI, which was probed through conve...

In situ immobilization of heavy metals in sediments has been considered as a low-cost and eco-friendly remediation method. this study, biochar (BC) BC-nanoscale zero-valent iron composite (nZVI/BC) treatments with different doses were conducted to immobilize Cd situ. The performance BC nZVI/BC changing mobility bacterial community sediment was investigated, their efficiencies at various pH valu...

In the process of water treatment, excessive nitrogen and phosphorus pollutants are great concern. Therefore, we prepared nanoscale zerovalent iron loaded on sediment-based biochar (nZVI-SBC) to conduct nitrate phosphate removal at same time. The characterization demonstrated that nZVI-SBC was successfully synthesized, which had obvious advantages for larger specific surface area better dispers...

BACKGROUND In recent years, pollution of soil and groundwater caused by fuel leakage from old underground storage tanks, oil extraction process, refineries, fuel distribution terminals, improper disposal and also spills during transferring has been reported. Diesel fuel has created many problems for water resources. The main objectives of this research were focused on assessing the feasibility ...
