UV/H2O2 coupled with adsorption in the decolorization and phytotoxicity effects of dye mixtures
Ortega Tapia A., Alvarez Marroquin C., Cardona Rendón L., Arroyave Quiceno C., (Corresponding) Aristizábal Castrillón A.
Topic:
Advanced oxidation processes
UV/H2O2 is an effective process for the decolorization of dyes in water; However, after treatment if complete mineralization is not achieved the toxicity of the wastewater usually increases due to the generation of intermediated more toxic than the dye. Thus, a subsequent process to reduce toxicity...Read more

Topic:
Advanced oxidation processes
In the present work, the potentiality of the hydrodynamic cavitation (HC) for the degradation of organic pollutants from industrial effluents has been studied. Cavitation is a phenomenon of formation, growth, collapse of microbubbles or cavities, in a few milli- to microseconds and releases large...Read more
Coal fly ash zeolites as adsorbents for effective removal of heavy metals and dyes from contaminated waters
Zgureva D., (Corresponding) Boycheva S., Behunová D., Václavíková M.
Topic:
Wastewater treatment
Recently, the purification of enormous amounts contaminated industrial, agricultural and municipal waters increases the demands of low-cost and technologically feasible techniques. The application of natural zeolites in wastewater treatment is known from many years. A feasible approach for...Read more

Degradation of textile dyes in water by gas-liquid NSP-DBD plasma
MEROPOULIS S., (Corresponding) AGGELOPOULOS C.
Topic:
Advanced oxidation processes
Textile dyes represent some of the most complicated environmental pollutants due to their variety and complex structure. Cold atmospheric plasma (CAP) is regarded as a highly competitive advanced oxidation process towards the removal of organic pollutants from wastewater. In this study, a gas-...Read more
Removal of wood dyes from aqueous solutions by sorption on un-treated pine sawdust
Pimentel C., Freire S., Gómez-Díaz D., (Corresponding) González-Álvarez J.
Topic:
Wastewater treatment
Synthetic dyes are extensively used in industry for various applications among which is the preparation of dyed wood veneers. The discharge of effluents containing dyes is of great concern due to their toxicity, mutagenicity and carcinogenicity and causes serious environmental problems. In this...Read more
Photocatalytic degradation of magenta effluent from the printing industry with composite catalyst
(Corresponding) Kerkez D., Pucar Milidrag D., Bečelić-Tomin M., Gvoić V., Kulić Mandić A., Leovac Maćerak A., Tomašević Pilipović D.
Topic:
Wastewater treatment
Water pollution is one of the most current problems related to human life and survival. The high degree of pollution of the human environment is contributed, among other things, by the discharge of industrial wastewater into rivers, among which wastewater from the graphic industry is of great...Read more

Aqueous wastewater treatment with aluminum oxide, silica, and alginite
Bankole A., (Corresponding) Thiemann T.
Topic:
Wastewater treatment
The adsorption of different types of dyes and stains over inorganic adsorbent materials such as silica, and aluminum oxide (basic and acidic) as well as over a mineral with an organic component, alginite, has been studied, with the idea of treatment of remnant dye solutions and solution wastes from...Read more
Adsorption-desorption of methylene blue dye onto marine sediments: Kinetics and equilibrium studies
(Corresponding) Vagi M., Leventelli M., Petsas A.
Topic:
Environmental pollution
The present study concerns the investigation of the sorption and desorption phenomena of methylene blue (MB), which is an organic molecule used as a synthetic dye in several industries. For that purpose, the batch equilibrium technique was applied by using three marine sediments that were...Read more
