Catalytic Ozonation using Iron-Doped Water Treatment Sludge as a Catalyst for Treatment of Phenol in Synthetic Wastewater

Environment and Natural Resources Journal, 2019
In this study, iron (Fe)-doped water treatment sludge, designated as Fe/WTS, was prepared by a hydrothermal method using phosphoric acid and impregnation with ferric nitrate. The results from X-ray diffraction (XRD) confirmed the presence of Fe loaded on

Removal of Methylene Blue and Congo Red Dyes Using Sustainable and Eco‐Friendly Bioadsorbents: A Review

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The continuous increasing discharge of synthetic dyes into aquatic systems seems to be an important environmental and health risk due to their high toxicity and resistance to biodegradation. Among these dyes, methylene blue (MB) and Congo red (CR) are widely used in textile and industrial applications, necessitating sustainable and efficient ...

Performance Investigation of Eco‐Friendly Refrigerant Mixtures as an Alternative to R134a in Vapour‐Compression Refrigeration System

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The growing impacts of climate change and energy scarcity demand environmentally sustainable refrigeration solutions. This study investigates eco‐friendly refrigerants (R152a, R290 and R600a) and their optimized ternary mixture as alternatives to R134a. Four blend compositions were analysed using experimental testing and REFPROP 10.0 modelling

Kinetic studies of catalytic ozonation of atrazine

Croatica Chemica Acta, 2008
Cilj ovog rada bio je istražiti raspad atrazina ozoniranjem uzoraka modelne i izvorne pitke vode korištenjem Pt-katalizatora, te određivanje učinkovitosti tog katalizatora. Konstante brzine raspada atrazina katalitiziranim i nekataliziranim ozoniranjem su određene samo za uzorke modelne vode, a aktivacijska energija i red reakcije u odnosu na ozon su ...

Oxidation of clofibric acid in aqueous solution using a non-thermal plasma discharge or gamma radiation

, 2017
In this work, we study degradation of clofibric acid (CFA) in aqueous solution using either ionizing radiation from a $^{60}$Co source or a non-thermal plasma produced by discharges in the air above the solution.
