Strategies for hydrogen peroxide dosing based on dissolved oxygen concentration for solar photo-Fenton treatment of complex wastewater

by

Sixto Malato et al. View all

Hydrogen peroxide consumption is known to be one of the key parameters of the photo-Fenton process responsible for its high operating costs. The purpose of this study was to find out whether adding dissolved oxygen to the reaction medium in a continuous stream of pure oxygen or air with different H...

The effect of humic acids on the removal of atrazine from water in a continuous photocatalytic membrane reactor

by

Karabelas A.J. et al. View all

Advanced Oxidation Processes

This paper examines the effect of humic acids (HA) and other solution constituents (Ca 2+, Mg 2+, Na +), frequently encountered in potable water sources, on the removal of a well-known herbicide, atrazine (ATR), by a laboratory-scale pilot Photocatalytic Membrane Reactor (PMR) system. Experimental...

Effect of oxidants in the photocatalytic degradation of DEET under simulated solar irradiation in aqueous TiO2 suspensions

by

Ioannis Konstantinou et al. View all

Advanced Oxidation Processes

Recently, considerable efforts have been devoted to overcome a major limitation in semiconductor photocatalysis, the recombination of photogenerated e --h + pairs which leads to reduced quantum yields. Considering the impacts of various parameters on the photocatalytic degradation efficiency, our...

Hydrothermal synthesis of iron oxide photo-Fenton catalysts: the effect of parameters on morphology, particle size and catalytic efficiency

by

Adrián M.T. Silva et al. View all

Advanced Oxidation Processes

Iron oxide materials were synthesized by an easy and rapid hydrothermal method using different iron precursors (FeCl 3∙6H 2O, Fe(NO 3) 3∙9H 2O and K 4Fe(CN) 6∙3H 2O), solution pHs (acid and basic) and reaction times (3 h and 6 h). The synthesized materials were thoroughly characterized by...

TiO2 photocatalytic degradation of caffeine and ecotoxicological assessment of oxidation by-products

by

Giusy Lofrano et al. View all

Advanced Oxidation Processes

The photocatalytic degradation of caffeine has been investigated in aqueous suspensions of titanium dioxide (TiO 2) by monitoring process efficiency at varying TiO 2 (25 - 175 mg l -1) and initial drug concentrations (0.5 - 9.5 mg l -1). The use of the response surface methodology (RSM) allowed to...

Modelling micropollutant removal by solar photo-Fenton

by

José Antonio Sánchez Pérez et al. View all

Advanced Oxidation Processes

This paper is focused on modelling the degradation of micropollutants by solar photo-Fenton at pilot plan scale. To this aim, a three pesticide mixture (acetamiprid, thiabendazole and imazalil, 100 μg l -1 each) was treated by photo-Fenton in simulated secondary effluent. The model covered a wide...
