This paper reports on a systematic study of the degradation of anthracene and phenanthrene in sandy soil treated with an aqueous solution of KMnO 4. A kinetic model was developed based on the soil/solution ratio to predict the degradation rates of anthracene and phenanthrene. The degradation...

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...

The present paper discusses an integrated electrochemical decolorization/degradation treatment procedure of indigo carmine dye, which comprises electrocoagulation, electrooxidation and advanced electrochemical oxidation using the electro-Fenton process. The electrocoagulation process is performed by...

Tubular halloysite clay mineral and nanocrystalline TiO 2 were incorporated in the preparation of nanocomposite films on glass substrates via sol-gel method at 450ºC. The synthesis involves a simple chemical method employing nonionic surfactant molecule as pore directing agent along with the acetic...

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...

Trichloroethylene (TCE) is found in all mediums of environment in varying concentrations. Over the past 25 years, many engineered systems have been devised for its complete and sustainable degradation. This study reviews the environmental factors that influence the TCE pollution in environment and...

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...

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...

The aim of this study was to assess the feasibility of co-digesting lipids originated from domestic wastewater along with sewage sludge. Three lab-scale single stage mesophilic anaerobic digesters were operated under a constant hydraulic retention time (15 days). One system (C) was fed on a daily...

Olive oil mill solid residue (OMSR) is the solid waste generated during olive oil production process in three-phase olive mills. It consists of the remaining pulp of olive processing after the extraction of oil, as well as the cracked seeds of the olive fruits, containing thus mainly lignocellulose...

This study examined the toxicity potential of total suspended particulate in the airshed of a haulage vehicle park located in a major highway connecting Lagos, the commercial centre of Nigeria to its other parts. It has an approximate area of 0.6 km2. Ambient air total suspended particulates (TSP)...

The unintended release of hydrocarbons into the environment can negatively impact human and animal health, and could further change the characteristics of soils. The aim of the present work was to investigate the rate of biodegradation at 10 and 20% diesel fuel in contaminated soil amended with 10%...

The use of organic manures as amendments to improve soil organic matter level and long term soil fertility and productivity is gaining importance. The disposal of the great quantity of organic wastes produced by the municipal, agricultural and agroindustrial activities, is causing energetic...

Treatment of young landfill leachate, collected from municipal solid waste site of city of Konya, was investigated by using the Fenton process. The leachate itself showed the characteristics of pH 7.25, COD 38.2 g L-1 and BOD5 22 g L-1. Ratio of BOD5 to COD with 0.58 indicates that leachate can be...

Solar assisted Photo Fenton was compared with advanced oxidation processes for their color and COD removal efficiency and cost effectiveness. H2O2 alone appeared to be inefficient to reduce color and COD content of any effluent. The performance of Fenton process was slightly better, color and COD...

Urban stormwater runoff constitutes a non-point source pollution, which contributes in degradation of water bodies’ quality (USEPA, 2002). European Union’s environmental policy includes water environment protection and preservation by adopting a series of directives, 2000/60/EC (Water Framework...
