This study uses a completely randomized design (CRD) with 5 variations of contact time is namely 30, 60, 90, 120, 150 minutes. Each treatment was repeated twice. The results showed that the best contact time in adsorbing Fe was 120 minutes with an amount of adsorbed is much 94.97 %. Keyword : Biosorption, elephant grass, metal iron } }
