Removal of Acid Red 18 dye from Aqueous Solutions Using Nanoscale Zero-Valent Iron
Background and Purpose:Organic dyes with a complex structure are often toxic, carcinogenic, mutagenic, non-biodegradation and stable in the environment and if released to the environment without treatment can endanger the environment and human health. The aim was to evaluate the performance nanoscalezero-valent iron (NZVI) in the removal of dye acid red 18 (AR18) from aqueous solutions. Materia...
متن کاملAqueous phosphate removal using nanoscale zero-valent iron
Nanoscale zero-valent iron (NZVI) particles have been used for the remediation of a wide variety of contaminants. NZVI particles have high reactivity because of high reactive surface area. In this study, NZVI slurry was successfully used for phosphate removal and recovery. Batch studies conducted using different concentrations of phosphate (1, 5, and 10 mg PO4 -P/L with 400 mg NZVI/L) removed *...
متن کاملSonocatalytic degradation of p-chlorophenol by nanoscale zero-valent copper activated persulfate under US irradiation in aqueous solutions
In this study, nanoscale zero-valent copper (nZVC) as catalyst activated persulfate (PS) was used for the degradation of p-chlorophenol (p-CP) under ultrasonic (US) irradiation in aqueous solution. The effect of different operational parameters such as solution pH (3.5-10.5), PS concentration (1-7.5 mm/L), nZVC dosage (5-35 mg/L) and initial p-CP concentration (10-100 mg/L) were evaluated at di...

متن کاملEmission of Polycyclic Aromatic Hydrocarbons from Contaminated Sediments
Contaminated sediments contain a variety of volatile and semi-volatile hydrocarbons, which are released into the air, when these sediments are stored in confined disposal facilities (CDFs). Polycyclic aromatic hydrocarbons (PAHs) are one class of sediment contaminants that of great interest, since they are carcinogenic and pose a significant health hazard. Hence quantitative data and models are...
