Background/Objectives: In this study, modification of Empty Fruit Bunch (EFB) fibers as a means to recover ammonia nitrogen from a synthetic solution was investigated. Methods: The EFB fiber was modified using sodium hydroxide. Adsorption-desorption studies of ammonia nitrogen into the modified EFB fiber were investigated Findings: The increase in adsorption capacity was found to be proportional with the increase of pH up to 7, temperature and ammonia concentration. The maximum adsorption capacity is 0.53-10.89 mg/g. The attachment of ammonia nitrogen involves ion exchange-chemisorption. The maximum desorption capacity of 0.0999 mg/g. Applications: This study can be used as a baseline for designing a low cost adsorbent system for ammonia nitrogen recovery drainage and industrial wastewater as well as EFBs-palm oil mill effluent composting.
