Reductive degradation of perfluorinated compounds in water using Mg-aminoclay coated nanoscale zero valent iron

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...

Aqueous 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 *...

Reductive degradation of azo dyes in aqueous solution by zero-valent iron

Kinetics of zero-valent iron remediation of two azo dyes in aqueous solution were investigated. Both show pseudo first-order reaction kinetics. Typical apparent reaction rate constants (k) are 0.70 min"' at 33.3 revolutions per second, k decreases with both increased pH and initial dissolved oxygen content increased over 5 mg l", but increases with both increasing iron conc­ entration and mixin...
