Abstract

The problem of treating methylene blue dye (MB) was considered using recycled waste tires. Treating waste by the application of other wastes is a resource-saving pollution treatment strategy. Previous MB treatment methods are either expensive or have high energy demands. In this study, two pollution treatments were connected via carbon pyrolysis. Waste tire pyrolysis by high-temperature microwaves produced pyrolytic carbon, which was then used to adsorb MB. This is because of its unique pore structure and large specific surface area. The results showed that recycled pyrolytic carbon benefits the MB adsorption reaction as a spontaneous endothermic reaction. Empirically, the maximum adsorption capacity of pyrolytic carbon for MB was found to be 71.6 mg g⁻¹ at pH 7 and 298 K. These recycling processes have low cost and low energy requirements, compared to previous studies.
