Removal of Synthetic Dyes By Adsorption Using Treated Oil Palm Waste Biomass

The utilization of dyes such as Methylene Blue which is categorized as cationic dye and Acidic Orange as anionic dye in several industries are widespread and leads to environmental deteriorations and may affect the human and aquatic life. These dyes are toxic and the discharge of dyes into water is harmful to aquatic organism, human health and to the environment. Thus, the method of removing the dye is being proposed by the researcher since it at utmost importance to keep the sustainable development. The most effective method to remove the dye is adsorption by activated carbon but it is costly due to the usage of coal as the primary source. However, the alternative source is being introduced which is agricultural waste products. The oil palm mill currently have a massive number of biomass leftover and it is been thrown away to the landfill which lead to the pollution. For example, the Empty Fruit Bunch (EFB) and Mesocarp Fiber (MF) are one of the contributors of waste disposal. Thus, the EFB and MF will be tested as the agricultural activated carbon for the dye removal in this study. The parameters that will be studied are the initial concentration of adsorbents which range from 50 mg/L to 250 mg/L, contact time between 10 minutes to 120 minutes. Initial pH of solution ranging from pH 2 to pH 9 as well as the dosage of adsorbents varied from 0.1 g to 0.5 g.
