Modeling of heterogeneous Fenton process for dye degradation in a fluidized-bed reactor: Kinetics and mass transfer

Silkworm cocoon derived N, O-codoped hierarchical porous carbon with ultrahigh specific surface area for efficient capture of methylene blue with exceptionally high uptake: kinetics, isotherm, and thermodynamics

“…1 Water contamination caused by these industries has drawn more and more attention, since almost all dyes are poorly biodegradable or resistant to environmental conditions and, therefore, create major problems in the treatment of wastewater stemming from the dyeing industry. 2 Currently, various treatment methods including physical, chemical and biological schemes have been developed to remove dyes from wastewater, such as photocatalytic degradation, [3][4][5][6] electrochemical degradation, 7,8 photochemical degradation, 9,10 sonochemical degradation, [11][12][13] sonocatalytic degradation, 14,15 Fenton-like degradation, [16][17][18] photo-Fenton degradation, [19][20][21] advanced oxidation process, [22][23][24][25] electro-Fenton degradation 26,27 and adsorption. [28][29][30][31][32][33][34][35] Among those, adsorption is proven to be a potentially powerful technique for removing pollutants from contaminated aqueous media.…”

Removal of Patent Blue (V) Dye Using Indian Bael Shell Biochar: Characterization, Application and Kinetic Studies

“…Several methods are conventionally used in water treatment facilities for the treatment of wastewater containing the excess level of dyes, including oxidation (photochemical and electrochemical) [10,11], Fenton's process [12], membrane separation [13], ion-exchange [14], coagulation [15] and biodegradation [16]. These methodologies are nonetheless found to suffer from several shortcomings such as generation of sludge, applicability to a narrow range of dyes, production of toxic intermediates and low cost-efficiency [17,18].…”
