“…The reason for this situation can be explained by the active sites on the surface of biosorbents [4]. In all biosorbents, qe increased as the initial dye concentration increased, consistent with the literature [17]. It was observed that the 𝑞𝑒 values of sage tea and tarragon plant were very close to each other, and it was calculated that tarragon reached the highest 𝑞𝑒 as 49 mg/g.…”

“…It has been reported that the reason for this situation is that GO has a negatively charged surface [23]. In a study in which Momordica charantia L. leaves were used as biosorbent, it was determined that MO biosorption followed the Freundlich isotherm and PSO [17]. Compared to the literature, it is thought that efficient results are obtained from the biosorbents we use in MO removal.…”

In this study, sage, chamomile, and tarragon leaves, which are used as spices and consumed as beverages in daily life, were considered as different biosorbents for water purification by biosorption. At the same time, the biosorption processes were modeled using evolutionary computation-based automatic programming (AP) methods. The effects of initial dye concentration (10-200 mg/L), temperature (20-50 ⁰C), and contact time (0-120 min) on the biosorption processes were investigated. The highest biosorption capacity (49 mg/g) was obtained in tarragon biosorbent at a dye concentration of 200 mg/L after 120 min of contact time. The biosorption mechanism was found to follow Freundlich isotherm and pseudo-second order (PSO) reaction kinetics for all biosorbents. AP methods used the parameters of initial dye concentration, temperature, and contact time to model the biosorption capacity obtained from the experiments. According to the simulation results, the methods successfully modeled the biosorption capacities with R^2 values as high as 0.99 for each biosorbent. This study demonstrated that the effects of biosorption processes can be studied not only by experiments but also by simulations.
