We investigated the ultrasound-assisted adsorption of Basic Blue 41 (BB41) dye from aqueous solutions using a green and low-cost adsorbent such as a Salda mud (SM) in our study. BET, FTIR, and SEM techniques were used to determine the morphology and the functional groups of SM before and after dye adsorption. Furthermore, we calculated different adsorption kinetic, isotherm, and error models (SSE, HYBRID, and ARE) parameters to evaluate the optimum experimental conditions such as the initial dye concentration of BB41 (6.25-50 ppm), SM dose (0.05–0.2 g), pH (3–10), and sonication time (400-3600 s). The value of uptake (%) of SM for BB41 was %94 at 50 ppm,25 °C at 3600 s. Following this, we found that the pseudo second-order (Type2) model of BB41 was the best fitted model with highest R2 (0.973-0.999) values. We developed a simple, low-cost, and fast to remove BM41 from water using natural and efficient SM adsorbent, which exhibited superior adsorption performance in wastewater treatment under ultrasonic irradiation.
