Kinetic Study of Degradation of Basic Turquise Blue X-GB and Basic Blue X-GRRL using Advanced Oxidation Process

Abstract

This study focuses on application of advanced oxidation (Photo-Fenton) processes to decolorize Basic Turquise Blue (BTB) X-GB 250% and Basic Blue (BB) X-GRRL 250% dyes. The percent decolorization was studied in terms of effect of variation in intensity of UV light at optimum conditions of all the parameters (pH = 3.0, H2O2 = 4.8 mM, FeSO4 = 1.6 mM, temperature = 50 °C, time = 80 min for BTB X-GB, and pH = 5.0, H2O2 = 5.6 mM, FeSO4 = 2.0 mM, temperature = 40 °C, time = 60 min for BB X-GRRL). Maximum decolorization was obtained at maximum intensity (15660 counts/min) of UV light as 96.17% for BTB X-GB and 88.48% for BB X-GRRL. First order, 2nd order and BMG kinetic models were used to analyze the data obtained for intensity of UV light. BMG model gives us the higher values of correlation coefficients for all data of both the dyes. The results have shown that Photo-Fenton oxidation process is the beneficial and effective for oxidation treatment of waste water effluents containing dyes as main pollutants.

A Study of Treatment of Reactive Red 45 Dye by Advanced Oxidation Processes and Toxicity Evaluation Using Bioassays

“…Dyes are chemically stable compounds and are a serious problem when dealing with textile waste effluent. Being highly soluble and environmentally problematic compounds, reactive dyes are the most discussed dyes in the literature [1]. Textile waste effluent reduces water transparency and sunlight penetration which affect aquatic life when mixed with ground and surface waters [2].…”

ZnO, CuO and Fe2O3 green synthesis for the adsorptive removal of direct golden yellow dye adsorption: kinetics, equilibrium and thermodynamics studies

“…Textile industry use huge amount of fresh water in the production and processing, which is discharged into the environment without treatment and is responsible for environmental degradation [7][8][9][10][11] Research has been progressed in the last two decades on advanced wastewater treatment techniques. The conventional techniques like oxidation, coagulationflocculation, membrane separation, electro-precipitation, ion exchange are insufficient to deal with the wastewater treatment due to cost and secondary pollution issues [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. The adsorption is a proficient to treat the wastewater versus other methods employed for wastewater treatment [28][29][30][31][32].…”

UV/H2O2, UV/H2O2/SnO2 and Fe/H2O2 based advanced oxidation processes for the degradation of disperse violet 63 in aqueous medium

“…Now a days, the release of industrial sewages that contain organic dyes causes water pollution such as lakes and rivers [1][2][3]. The degradation of organic contaminants and dyes in wastewater has become the problem of environmental concern [4].…”
