Abstract
ABSTRACT Within the scope of end-of-life tires (ELTs) management, recovery of tires considering circular economy approach is becoming increasingly important. This study aims to examine the sorptive behavior of methylene blue (MB) and Rhodamine B (RB) dyes from synthetic textile industry discharge with a carbon-based sorbent (CBM) recycled from ELTs as a novel patented method and used for the first time for organic dye removal in the literature. The CBM was characterized by using fourier transform infrared (FTIR) and scanning electron microscopy (SEM) for structural and morphological properties. XRD (X-ray diffraction) and XPS (X-ray photoelectron spectroscopy) analysis were used for phase composition and surface chemistry of CBM. The maximum adsorption capacity of MB and RB on CBM is 681.14 and 85.26 mg/g, respectively. For the reusability of the CBM, the regeneration experiment was carried out and MB and RB removal performance of CBM gradually decreased with increasing adsorption cycles. The results show that it is possible to utilize CBM which in terms of ensuring the reuse of wastes within the scope of industrial symbiosis, as an effective adsorbent in dye removal. This study reduces environmental pollution by converting the end-of-life tires into carbon-based material for water/wastewater treatment provides a “win-win” solution to improve waste management.
