Topic:
Heavy metals in the environment
The integrated effects of increased atmospheric CO2 and heavy metals pollution may have important implications for plant growth. Elevated atmospheric CO2 can affect plant defences through its significant effects on plant growth. Some studies have found that elevated CO2 can decrease oxidative...Read more
Hydrogen production from cotton wastes by mean of dark fermentation
(Corresponding) Sołowski G., Konkol I., Shalaby M., (Corresponding) Cenian A.
Topic:
Energy technologies and sustainability
Dark fermentation of textile wastes is discussed in the paper. In the experiment were used cotton wastes. Before fermentation the cotton was hydrolyzed using 0.1 M of HCl. The inoculum was pretreated using heat shocked for 0.5 h at temperature of 105°C. The fermentation was carried out under...Read more
US/H2O2 combined technology applied to the paracetamol oxidation
Villota N., (Corresponding) Jose L.
Topic:
Advanced oxidation processes
This study analyzes the colour acquired by oxidizing paracetamol aqueous samples through the combined US/H2O2 technology. When operating with only the action of the waves [US]=1.0 kWh/mmol C8H9NO2, the water acquires progressively hue according to a ratio of 0.0004 AU/min, with a degradation output...Read more
FENTON REAGENT IN COMBINATION WITH UV LIGHT AND ULTRASOUND WAVES APPLIED FOR CAFFEINE OXIDATION
Villota N., Lomas J., Lombraña J., Ferreiro C.
Topic:
Advanced oxidation processes
The oxidation of aqueous caffeine solutions ([Ca]0=100.0 mg L-1) was analyzed, operating at pH=3.0 and 25ºC using different AOPs, which combine the Fenton reagent ([H2O2]0=15.0 mM and [Fe2+]0=20.0 mg L-1) with low power UV light (15W,), medium (150W), and high (720 W). The Fenton reagent, combined...Read more

Topic:
Climate change mitigation and adaptation
Climate change is increasingly been called a ‘security’ problem, and there has been speculation that climate change may increase the risk of violent conflict. In this paper, the impact of climate change on the indicators such as war and insecurity, water and food resources, poverty development,...Read more

Application of some clay minerals to eliminate the hazards of heavy metals in contaminated soils
Topic:
Heavy metals in the environment
Soil pollution by heavy metals has serious hazards on microorganism plants, human being and ecological environment. Many approaches have been introduced to overcome the problem of contaminated soils by heavy metals as cadmium, copper and nickel.
A laboratory experiment conducted using zeolite and...Read more
