Oxidation of waters containing 100.0 mg L-1 of caffeine was conducted by a sono-Fenton treatment employing an ultrasound power of 720W at pH=3.0 and T=25°C. The catalytic action of ferrous ion was studied in a range of [Fe2+]0=0-100.0 mg L-1, using oxidant ratios of [H2O2]0=250.0 mM. The oxidation...Read more
Oxidation of waters containing 100.0 mg L-1 of caffeine was conducted by a sono-Fenton treatment employing an ultrasound power of 720W at pH=3.0 and T=25°C. The oxidizing action of hydrogen peroxide was studied in a range between [H2O2]0=0-250.0 mM, using iron ratios of 0.7 mol Fe2+/mol C8H10N4O2...Read more
This study analyses 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
Comparison of caffeine oxidation by Fenton reagent in combination with UV light and ultrasound waves
(Corresponding) Villota N., Lomas J., Ferreiro C., Lombraña J.
Topic:
Advanced oxidation processes
The oxidation of aqueous caffeine solutions ([Ca]0=100.0 mg L-1) was analysed, 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

(Corresponding) Žgajnar Gotvajn A., Carvalho A., Marinšek M., Kalčikova G.
Topic:
Wastewater treatment
Biochar can be produced usig variety of waste biomass to achieve goals of zero waste management and circular economy. It has been used as adsorbent in the past for water and wastewater treatment. Recetly, the application of natural porous materials for removal of emerging pollutants gained a lot of...Read more
Ozonation, advanced oxidation and hydrodynamic cavitation for removal of persistant pollutants
(Corresponding) Žgajnar Gotvajn A., Čehovin M.
Topic:
Advanced oxidation processes
Ozone is commonly used in advanced oxidation processes (AOPs) in combinations with hydrogen peroxide (H2O2) and UV radiation (UV). Hydrodynamic cavitation (HC) has been experimentally proven to result in effects, typical of AOPs. Combinations of AOPs with O3, H2O2 and UV, and HC (with cavitation...Read more
Catalytic Enhancement of Ozone-Based Processes for Removal of Selected Antibiotics from Wastewaters
(Corresponding) Žgajnar Gotvajn A., Derco J., Antončič T., Vrabel M.
Topic:
Advanced oxidation processes
The aim of our work was to use advanced oxidation processes based on formation of reactive hydroxyl radicals (OH·) due to ozonation and its combination with H2O2, Fe2+ as catalyst and UV light for removal of Amoxicillin and Levofloxacin from model wastewaters at different pHs. Removal efficiencies...Read more

Topic:
Microplastics in water treatment: fate, toxicity assessment and removal technologies
The aim of this study was to evaluate the inhibition on the biogas production caused by microplastics (MPs). Wastewater treatment plants (WWTPs) are receptors of MP. After wastewater treating, more than 90% of MP could be retained in the sludge. Anaerobic digestion of the excess sludge can help...Read more
