Abstract Green-based materials represent a new promising class of ecofriendly and economic adsorbents. Herein, nano zero-valent iron supported-lemon derived biochar (NZVI-LBC) was prepared for the first time examined in adsorptive removal methylene blue as model pollutant. Different characterization tools were used to ensure successful fabrication NZVI-LBC composite including FTIR, XRD, TEM, XP...

conclusions changes of ph could remarkably affect the efficiency and oxidation rate of mtbe. in particular, the amount of kap in terms of oxidation declines substantially by moving away from the optimum ph range. in this study, ph 3.5 was considered as the optimal ph in h2o2/nzvi/ultrasonic oxidation process, with the elimination of about 89.56% of the high mtbe concentration. in general, we ca...

In this work, the synchronous removal of Cr(VI) and bisphenol A (BPA) in a heterogeneous Fenton process with sulfidated nanoscale zero-valent iron (S-nZVI) as reductant catalyst was systematically evaluated. Compared to other systems including S-nZVI or H2O2 alone, simultaneous BPA degradation could be achieved S-nZVI/H2O2 system at an optimum pH 3. It was, interestingly, found that 7.8% 98.2% ...

Abstract In this study, we prepared and characterized ceramsite-supported nanoscale zero-valent iron (nZVI). Malachite green (MG) dye removal from aqueous solutions using a fixed-bed reactor packed with the above composite material was investigated. This research carried out according to prophase study of preparation characterization ceramsite for water treatment sintering method solid wastes. ...

The co-contamination of soils with heavy metals and organic contaminants is a problem that requires different innovative approach to remediate these kinds sites. nature two contaminant groups makes the complicated. Recently, zero-valent iron nanoparticles (nZVI) application has been integrated bioremediation be used for remediation halogenated organics. However, use this process co-contaminated...

Nanoscale zero-valent iron particles (NZVI) produced by using green tea (GT) extract as a reductant can remove Cr(VI) from water effectively, which be utilized in groundwater remediation. In order to define the reaction mechanism and removal effect aquifer, this study, GT-NZVI were prepared measured some characterization methods their surface performance, then batch one-dimensional experiments ...

Supported nano zero-valent iron is receiving great attention nowadays due to its effectiveness in treating heavy metal pollutants. Therefore, this study aimed investigate the of granitic residual soil-supported (Gr-nZVI) for removal metals Pb2+, Cu2+, Co2+, Cd2+ Ni2+ and Zn2+ mixture solutions under different experimental conditions batch equilibrium tests. In study, Gr-nZVI was successfully sy...
