| Abstract | ||
| The discharge of wastewater containing synthetic dyes from industries, particularly the textile sector, poses significant environmental and health challenges. Waste coffee grounds were examined in this work as a low-cost, environmentally friendly, and sustainable reducing agent for the removal of dyes from aqueous solutions. Coffee waste was collected and pretreated before using. Two methods were used for treating simple treatment and ultrasonic treatment. The waste coffee samples were characterized using X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The sample catalytic activities were evaluated by reduction of Methylene blue (MB) and Remazol red (RR) dyes. According to the results, waste coffee showed excellent removal efficiency for both MB and RR dyes. The catalytic activity of waste coffee materials is improved by ultrasonic treatment. Ultrasonic treatment improves catalytic activity through raising active site dispersion, decreasing particle size, and improving surface characteristics. The potential of using spent coffee as a sustainable dye remediation method in wastewater treatment systems is highlighted by this study. | ||
