Özet
In this study, magnetic iron-coated mint leaves based carbon adsorbent (MMC) was synthesized by the green synthesis method and the characterization of MMC was determined by SEM-EDX, FTIR and Raman analyses. In the study, to determine the adsorption capacities of MMC adsorbent for acid blue 193 and basic violet 7 dyes, studies were carried out at different pH, adsorbent dose, dye concentration and adsorption times, and the conditions for the best dye removal were determined. The highest acid blue 193 dye removal was achieved to 79.8% at pH 2 and 10 g/L MMC and the highest basic violet 7 dye removal was obtained as 98.6% at 5 g/L MMC and pH 11 using MMC adsorbent. The adsorption of dyes with MMC was by the pseudo second order kinetics and was more suitable for the Langmuir isotherm. In the adsorption of acid blue 193 and basic violet 7, the q(max) values with Langmuir isotherm were calculated as 15.55 and 27.55 mg/g, respectively. As a result, it has been thought that this MMC adsorbent, which is synthesized as a low-cost and environmentally friendly adsorbent, can be efficient in the acid and basic dyes removal from wastewater.
