Phenol removal from wastewater using eco‐friendly hybrid hydrogels

نویسندگان

چکیده

The intent of this study was to evaluate the ability low-cost polyacrylamide/starch hybrid hydrogels in removing organic pollutants from wastewater, using phenol as a model compound, besides investigating adsorption/desorption behavior function composition. results indicated that hydrogel with lowest amount starch and crosslinking agent exhibited maximum adsorption capacity, 21 mg g−1. isotherm data were described by Langmuir Freundlich models. According linear regression analysis, best fit among models for process. Furthermore, desorption revealed minimum about 60% release, indicating reusability wastewater treatment.

Effect of H2O2 Addition on Phenol Removal from Wastewater Using TiO2/Al2O3 as Photocatalyst

The photocatalytic oxidation of phenol in water in the band reactor with supported TiO2 catalysts was investigated. Modified anatase/Al2O3 catalysts were used as the photocatalysts. The main aim of these studies was to determine catalytic activity of TiO2/Al2O3 and V-TiO2/Al2O3 in the removal of phenol from water. The effectiveness was measured in the configurations: TiO2/UV/O2/H2O2, TiO2/O2/H2...

Optimization of peroxidase-catalyzed oxidative coupling process for phenol removal from wastewater using response surface methodology.

Hydroxylated aromatic compounds (HACs) are considered to be primary pollutants in a wide variety of industrial wastewaters. Horseradish peroxidase (HRP) is suitable for the removal of these toxic substances. However, development of a mathematical model and optimization of the HRP-based treatment considering the economical issues by novel methods is a necessity. In the present study, optimizatio...

Reactive nitrogen and phosphorus removal from aquaculture wastewater effluents using polymer hydrogels

We have developed poly(allyl amine hydrochloride) (PAA · HCl) polymer hydrogels, that efficiently remove nitrate (NO3 ), nitrite (NO2 ), and orthophosphate (PO4 ) nutrient anions from the aquaculture wastewater. The hydrogels were prepared by chemically crosslinking linear PAA · HCl chains with epichlorohydrin (EPI). The anion binding capacity of the pH sensitive polymer gels was measured in st...
