This research seeks to evaluate the efficacy of chitosan/OPT adsorbent (CSOPT) modified with imidazolium-based ionic liquid and acetic acid in eliminating the harmful malachite green (MG) dye through batch adsorption experiments. The CSOPT adsorbent was characterized using Scanning Electron Microscope with Energy Dispersive X-Ray (SEM/EDX) and Fourier Transform Infrared (FTIR) spectrophotometer. Key parameters, such as initial pH (3-8) and adsorbent dosage (0.02-0.10g), initial concentration (5, 10, 15 mg/L) and contact time (3-60 minutes) were investigated to determine the optimal conditions for maximal malachite green adsorption. The adsorption process adhered to the pseudosecond order kinetic model with a high regression correlation (R2 = 1.000) and a low chi-squared value (x2 = 0.05). The adsorption isotherm of MG on the CSOPT surface exhibited a multilayer stepwise pattern, denoted as type VI isotherms. CSOPT shows a high adsorption capacity of 1000 mg/g at pH 8 and room temperature (equivalent to 20 to 25°C). The desorption of MG using 0.01 HCl was only 5.7%, indicating the presence of electrostatic attraction, as well as other interactions like H-bonding and n-n interaction. These results suggest that the CSOPT adsorbent offers a practical and alternative solution for extracting MG from water. 2024 Thesis https://ir.uitm.edu.my/id/eprint/93880/ https://ir.uitm.edu.my/id/eprint/93880/1/93880.pdf text en public degree Universiti Teknologi MARA Pahang Faculty of Applied Sciences
