Reactive Black 5 dye degradation using filters of smuggled cigarette modified with Fe3+

Abstract

This study presents an attempt to solve two serious environmental problems: the generation of toxic effluents and solid waste disposal. The work proposes recycling cigarette filters with the purpose of degrading reactive dyes, which are used in the textile industry. Filters of smuggled cigarettes were recycled through Fe immobilization on their surface. The material obtained was characterized through Fourier transform infrared spectroscopy (FTIR), atomic absorption spectroscopy (AAS), scanning electron microscopy-energy-dispersive spectroscopy (SEM-EDS), and ultraviolet-visible spectroscopy (UV-vis). The factorial design revealed that the most suitable conditions for the degradation of Reactive Black 5 dye were obtained by using 1 g of material at pH 3.0 in a 100 mg L hydrogen peroxide solution. The material showed excellent performance in the Reactive Black 5 dye degradation process; in 60 min, 99.09 % dye was removed. At pH 7.0, the dye degradation was 72.67 %, indicating that the material prepared can be used at pH values greater than 3.0 without the occurrence of hydrated Fe oxide precipitation. Furthermore, the material showed no loss of catalytic activity after three degradation studies.

Upcycling of the Used Cigarette Butt Filters through Pyrolysis Process: Detailed Kinetic Mechanism with Bio-Char Characterization

“…The peak at 3468 cm −1 is attributed to the ν(O-H) stretching vibrations of hydroxyl groups in CAc. Namely, the range of wavenumbers between 3500 cm −1 and 3400 cm −1 can be attributed to the OH stretching present on the cellulose surface [ 39 ]. It can be noted that the mentioned region is important because OH groups may give information about the formation of a hydrogen-bond matrix inside the actual structure since OH groups can form hydrogen bonds with not only C=O (see later) but also with other groups, as, for example, another OH group or –O– group [ 40 ].…”

Investigating degradation metabolites and underlying pathway of azo dye “Reactive Black 5” in bioaugmented floating treatment wetlands

“…The presence of RB5 dye in water affects the performance of biological processes due to its toxicity or intrusion in the capability of enzymes (Iglesias et al 2013;Glugoski et al 2017;Lumbaque et al 2017;Bilal et al 2018). Therefore, the initial dye amount possesses a substantial role in the e ciency of the dye elimination process.…”

“…A number of scientific efforts have been applied to eradicate these hazardous chemicals from wastewater. 2,3 Various physicochemical techniques such as filtration, 4 adsorption, 5 precipitation, 6 and advanced oxidation processes (AOPs) have been reported. [7][8][9] AOPs are a set of chemical treatments designed to remove organic materials from wastewater by oxidation through reactions with reactive oxygen species.…”
