Optimasi Parameter Adsorpsi Rhodamine B Menggunakan Lempung Alam Maredan

---

Natural Maredan clay is an environmentally friendly and cost-effective adsorbent with significant adsorption efficiency. It is used as an adsorbent to remove Rhodamine B dye. This research aims to determine the optimal contact time, stirring speed, adsorbate concentration, and adsorbent dosage for Rhodamine B adsorption. The research method employed batch adsorption of Rhodamine B with optimized contact time (5, 10, 15, 20, and 25 minutes), stirring speed (100, 150, 200, 250, and 300 rpm), adsorbate concentration (40, 50, 60, 70, and 80 ppm), and adsorbent dosage (0.1; 0.3; 0.5; 0.7; and 0.9 grams). The natural Maredan clay was characterized before and after adsorption using Fourier Transform Infrared (FTIR) to identify the functional groups on the adsorbent. UV-Vis spectroscopy was used to analyze the final adsorbate concentration after the adsorption process. The optimal adsorption parameters were found to be a contact time of 10 minutes, stirring speed of 250 rpm, adsorbate concentration of 50 ppm, and adsorbent dosage of 0.9 grams, resulting in an adsorption efficiency of 94.11% and an adsorption capacity of 2.6396 mg/g. The adsorption kinetics followed the second-order pseudo-kinetic model with an R2 of 0.9979 and K2 of 0.2509 g/mg minute, while the adsorption isotherm followed the Langmuir isotherm with an R2 of 0.8309. Based on the second-order pseudo-kinetic and Langmuir isotherm models obtained in this study, the adsorption process occurs chemically and forms a monolayer.
