ABSTRACT
Rice husk is an abundant agricultural waste containing lignocellulosic compounds and silica, which have the potential to be used as a base material for adsorbents. This study aims to examine the effect of varying heating temperature and time on the physicochemical characteristics and adsorption capacity of rice husk as an adsorbent. Rice husk was heated at temperatures of 100°C, 125°C, 150°C, 175°C, and 200°C, for 60, 90, 120, 150, and 180 minutes. The best heating time and the best results were obtained, with the best heating time being 150°C and 150 minutes. FTIR characterization results showed changes in the intensity of the –OH, C–H, and Si–O functional groups after the heating process, which correlated with increased porosity and surface area. Adsorption tests on a 100 ml Methylene Blue solution with a concentration of 20 ppm using 1 gram of adsorbent showed that optimal conditions were obtained at a temperature of 150°C for 150 minutes, with an adsorption capacity of 1.12 mg/g and an adsorption effectiveness of 89%. Thus, temperature and heating duration play a crucial role in optimizing the performance of rice husk as an environmentally friendly adsorbent.
Keywords: rice husk, adsorbent, temperature, heating time, adsorption, methylene blue
