“…The Fenton reaction was initiated by adding the hydrogen peroxide in various concentrations (1-11 mM). The mixture was kept at a constant stirring of 120 rpm at the temperature of 23 °C for 60 min (Kecić et al, 2018a). The initial, as well as residual dye concentrations in the reaction mixture were determined by measuring the absorbance of the aqueous solutions at 636 nm by using UV/VIS spectrophotometer (UV 1800, Shimadzu, Japan).…”

Starting from the assumption that wastewater treatments can have a significant impact on the interactions between microplastics (MPs) and various pollutants in different matrices, a focus must be directed on examination of classic and redesigned treatments to remove synthetic dyes in the presence of MPs from wastewater. This paper investigates the potential application of Fenton-like process for the removal of water-based printing dye (Cyan) from aqueous solution containing MPs in a form of granulated polyethylene (PEg). The influence of five quantitative parameters on decolorization efficiency was investigated: initial dye concentration (20-180 mgL-1), nano zero valent iron (nZVI) dosage (0.75-60 mgL-1), PEg concentration (1-10 gL-1), hydrogen-peroxide concentration (1-11 mM) and pH value (2-10). A novel statistical approach, definitive screening design, resulted with the optimization process which yielded highest removal efficiency of 92% under following conditions: initial dye concentration of 155 mgL-1, nZVI dosage of 55 mgL-1, PEg concentration of 2.35 gL-1, H2O2 concentration of 2 mM and pH value 2.5. Available data indicate that in the future, wastewater containing MPs will dictate ways to reuse this water in terms of closing the water material cycle and reducing environmental pollution. Therefore, the industrial wastewater reuse is an important component of sustainable wastewater management practices, namely, water resource augmentation and pollutant reduction.

“…Nakon podešavanja pH vrednosti (AD110 Adwa), dodatkom 0,1 M rastvora ccH 2 SO 4 ili NaOH, uzorci su mešani u vremenskom periodu od 180 minuta, sa brzinom mešanja 120 o/min i konstantnom temperaturom od 23 °C. Nakon isteka vremena reakcije izmerena je apsorbanca na talasnoj dužini od 437 nm [3]. Sva merenja vršena su na UV/VIS spektrofotometru Genesys 10S, Thermo Fisher.…”

Predmet istraživanja ovog rada obuhvata tretman otpadne vode obojene žutom bojom i generisane nakon procesa flekso štampe, primenom homogenog Fenton procesa. Uticaj procesnih parametara na efikasnost obezbojavanja sintetičkog rastvora žute boje i realnog efluenta, kao i optimizacija procesa izvršeni su primenom statističke analize: definitive screening design. Fizičko-hemijska karakterizacija efluenta pre i nakon Fenton tretmana je obuhvatila merenje pH vrednosti, električne provodljivosti, temperature i mutnoće. Ispitivanje efikasnosti obezbojavanja vodenog rastvora grafičke boje vršeno je serijom eksperimenata na aparaturi za JAR test.

“…The lab-scale of heterogenous Fenton process was performed by a series of experiments on a JAR test apparatus (FC6S Velp scientific, Italy). The experimental procedure is described in detail in the paper by Kecić et al (7), where iron molybdate was used instead of nano zero valent iron as a catalyst. The decolorization efficiency was calculated according to equation [1]: % * 100 [1] where: A 0 is the initial dye absorbance of aqueous solution or printing effluent; A t is dye absorbance of aqueous solution or printing effluent after heterogeneous Fenton process.…”

“…Four continuous factors were considered, each having three levels: the low (-1), central (0), and high (+1), presented in Table 1. The limit values of the investigated variables have been selected according to estimated dye concentration in the wastewater sample and literature data (7,11,12). JMP 13 software was used for statistical analysis.…”

Heterogeneous Fenton catalyst Fe 2 (MoO 4 ) 3 was prepared and the process efficiency was evaluated for oxidation of water-based Cyan flexo dye in synthetic aqueous solution and printing wastewater. The removal process of printing dye was analyzed by UV/VIS spectrophotometry, while dye mineralization was evaluated by the determination of total organic carbon content and chemical oxygen demand. Four determinants of the heterogeneous Fenton system, including initial dye concentration, iron concentration, pH and hydrogen peroxide concentration were investigated. Statistical method, definitive screening design was applied to generate optimal operational conditions of the four variables, which maximizes the process of dye removal. The initial dye concentration of 20 mgL -1 , catalyst dosage of 0.75 mgL -1 , pH of 2 and H 2 O 2 concentration of 11 mM were chosen as the best operational conditions, contributing to 82% of the process efficiency. The Fenton process efficiency of 79% was achieved within the treatment of printing wastewater under optimal conditions for a 90 minute reaction time. The maximum COD removal efficiency was 61.1%, while 67% mineralization was achieved. The obtained results confirmed synergistic effect of Fe 3+ and MoO 4 2− which contributed to high catalytic activity and high heterogeneous Fenton efficiency.
