The search for new technologies for wastewater treatment has focused on the use of biomass as biosorbent materials with a good performance. The objective was to use coconut fiber disposed in Belém-PA in the removal of organic matter. The coconut fibers were dried at 80 °C (biosorbent 1) and 60 oC (biosorbent 2) for 24 hours, crushed and sieved. 50 mg of the biosorbents was stirred for 24 h in 20 mL of the wastewater sample and filtered. Was used the reflux titrimetric method using block digester Q-325M in the analysis of chemical oxygen demand (COD). The biosorbent 1 showed better adsorption capacity, with efficiency of 66 % (1 point) and 23 % (point 2). The biosorbent 2 adsorbed only 33 % (1 point), and 23 % (point 2). It was concluded that the use of coconut fiber in the wastewater treatment can be a good alternative for the recovery of contaminated water bodies.
