“…Dyes in textile industry are synthetic organic materials with complex structure and they are nonbiodegradable (2). In addition, dyes containing -N=N-azo group (azo dyes) are considered toxic and carcinogenic and may create serious effects on organisms in the water bodies and human health (3). There is a great variety in treatment of dye effluents in wastewater such as extraction via solvent, separation via membrane, advanced oxidation process, photodegradation, and adsorption (4)(5)(6).…”

Recently, utilization of biological adsorbents plays an important role in the removal of toxic dyes such as Eriochrome Black T (EBT) azo-dye as they are considered as being produced from natural renewable source, easy availability, low cost, and being environmentally friendly. In this study, vermicompost (VC) was utilized to remove Eriochrome Black T (EBT) azo-dye from aqueous solution along ultrasonic ultrasonic-assisted adsorption. The parameters such as pH, adsorbent amount, operating time, and initial EBT concentration were investigated. The highest adsorption capacity was obtained as 50.64 (mg-EBT g -1 -VC) at the pH of value of 2 after 2 minutes of ultrasonic adsorption. Pseudo first order kinetic model fitted very well with the experimental data (R 2 =0.9824). The determination coefficient of Temkin isotherm model (R 2 =0.8659) revealed that suggested model was compatible to experimental results. The results suggested that ultrasonic assisted adsorption of EBT onto VC could be cost-and time-efficient. Besides, the Scanning Electron Microscopy (SEM) analysis of adsorbent identified the surface structure morphology of VC. Moreover, functional groups of VC were detected after and before the ultrasonicassisted adsorption by using Fourier Transform Infrared Spectroscopy (FTIR). Thus, interaction mechanism between VC and EBT were determined.

“…About 70% of the dyeing wastewater utilized worldwide by dyeing industries is composed of azo dyes that have one or more azo bonds, which are toxic to many organisms and might cause the direct destruction of creatures in water [2,4]. Eriochrome Black T (EBT) dye belongs to the azo dyes, which have potential environmental hazards and constitute a direct threat to human health [5]. EBT is often used as an indicator in complexometric titrations; the application of EBT in industrial processes produces large amounts of waste effluent.…”

Sludge-derived activated carbon (SAC) was prepared by Fenton activation and calcination, and used as adsorbent to eliminate Eriochrome Black T (EBT) dye from aqueous media. The characterization results indicated that the produced SAC had a porous structure, high specific surface area, and abundant functional groups on its surface. The adsorption process was affected by pH, adsorbent dosage, time, and temperature. The adsorption capacity increased with temperature, and the highest adsorption capacity reached 178.2 mg·g−1 in 48 h at 318 K and pH 6. The results of the adsorption isotherm, kinetic, and thermodynamic analyses revealed that the adsorption of EBT onto SAC was naturally endothermic and spontaneous, involved both physical and chemical processes, and belonged mostly to the multilayer type of adsorption.
