Effect of system parameters and of inorganic salts on the decolorization and degradation of Procion H-exl dyes. Comparison of H2O2/UV, Fenton, UV/Fenton, TiO2/UV and TiO2/UV/H2O2 processes
A. Riga,A. Riga,K. Soutsas,K. Ntampegliotis,Vayos Karayannis,Vayos Karayannis,G. Papapolymerou +6 more
TL;DR: In this paper, the decolorization and degradation of commercial reactive azo dyes were studied using five advanced oxidation processes (AOPs): H2O2/UV, Fenton, UV/Fenton, TiO2 /UV and TiO 2/UV/H2O 2.
Journal ArticleDOI
Decolorization and degradation of reactive azo dyes via heterogeneous photocatalytic processes
K. Soutsas,Vayos Karayannis,Ioannis Poulios,A. Riga,K. Ntampegliotis,X. Spiliotis,G. Papapolymerou +6 more
TL;DR: In this paper, the decolorization and degradation of four commercial reactive azo dyes, namely Remazol Red RR, remazol Yellow RR, Procion Crimson H-exl and Procion Yellow Hexl, were studied using photocatalytic processes.
Journal ArticleDOI
Circular bio-economy via energy transition supported by Fuzzy Cognitive Map modeling towards sustainable low-carbon environment
TL;DR: A semi-quantitative assessment of the impacts of biowaste-based energy transition by engaging all relevant social stakeholders' evaluation in the strategic plan and using analytics and optimization algorithms to guide competent authorities and decision makers to sustainable energy transitioning towards decarbonization.
Journal ArticleDOI
Decolorization kinetics of Procion H-exl dyes from textile dyeing using Fenton-like reactions
TL;DR: The decolorization kinetics of three commercially used Procion H-exl dyes was studied using a Fenton-like reagent and the effect of the major system parameters (pH, concentration of H(2)O( 2) and Fe(3+) and initial dye concentration) on the kinetics was determined.
Journal ArticleDOI
Fuzzy Cognitive Map-Based Modeling of Social Acceptance to Overcome Uncertainties in Establishing Waste Biorefinery Facilities
Konstantinos Kokkinos,Evangelia Lakioti,Elpiniki I. Papageorgiou,Konstantinos Moustakas,Vayos Karayannis +4 more
TL;DR: A novel Fuzzy Cognitive Map (FCM) modeling approach is proposed in order to analyze the socio-economic implications and to overcome multiple uncertainties occurring in sustainable WBF development and implementation.
