The advanced oxidation process based on persulfate has a broad application prospect in the remediation of organic pollutants. As an effective, low-cost and environmentally friendly material, nano-zero-valent iron (nZVI) can effectively activate (nZVI/PS) to generate strongly oxidizing sulfate radical for removing pollutants environment. In this review, we first clarify activation pathway nZVI a...
This paper investigates the potential of nano zero valent iron impregnated cashew nut shell nanoparticles (NZVI-CNS) as an effective adsorbent for the removal of phenol from aqueous solution. The effect of initial pH, adsorbent dosage, contact time and temperature were determined by batch adsorption experiments. Langmuir and Freundlich adsorption isotherm models were applied to the adsorption e...
Sludge bulking causes loss of biomass in the effluent and deterioration of effluent water quality. This study explored the use of nano zero-valent iron (NZVI with an average particle size of 55 ± 11 nm) for sludge bulking control. In two Modified Ludzack-Ettinger (MLE) activated sludge treatment systems, a single dose of NZVI at the final concentration of 100 mg Fe per L in the mixed liquor red...
The increasing industrial development of recent decades has lead to the production of increasing quantities of waste containing heavy metals, elements often harmful to the environment, which in the past were not properly disposed of, thus inducing soil and groundwater pollution. In particular, chromium (Cr) and its derivatives are largely used in industries such as textiles, electronics, metall...
Background and purpose: Copper is a trace element that is used in various industries. Copper nano-particles are being used in different skin care products, lubricants, oils, polymers, metal covers, plastics, inks, etc. Previous studies have shown that both copper sulfate and copper nano-particles can induce cellular genotoxicity and DNA damage. So, this study aimed at evaluating and comparing g...
