...Ruta Ozola; Andrejs Krauklis; Juris Burlakovs; Maris Klavins; Zane Vincevica-Gaile; William Hogland Abstract Organic pollutants are widespread and a known problem for the environment. p -nitrophenol (PNP) is one such pollutant found in effluents from various industries involved with pesticides...

... (Mnt), the synthetic polyhydroxyl-Fe pillared montmorillonite (Fe-Mnt) was found to be somewhat similar to goethite in promoting the ability of specifically adsorbed Fe(II) to reductively transform 2-nitrophenol (2-NP). The 2-NP was efficiently removed within 30 min from solutions at the optimum...

Jovanović Abstract Phenol and its derivatives are regarded as ‘priority pollutants’ and p -nitrophenol ( p -NP), in particular, is of great interest due to its toxicity and frequent presence...

...-FeOOH, α-FeOOH, and α-Fe 2 O 3 ) for the reductive transformation of 2-nitrophenol (2-NP), using cyclic voltammetry (CV). Studies of Fe(II) adsorption and 2-NP reduction kinetics showed that an increase in pH gave rise to an elevated density of adsorbed Fe(II) on mineral surfaces, which further resulted...
